Are you wanting disc brake or rim brake?

I'm not really sure either rim or disc brakes would be the deciding factor. Disc brakes would be nice as it seems thats the way things are headed but they aren't a requirement for me. Ultimately, its about ride quality and fit for me with a little bit of aesthetics. I was recently fitted and those were the bikes that best fit me. I like the P5 but have read that you cannot have electronic shifters on the bull horns with the Magura brakes so that could be an issue.

I would not get a P5. I've heard of issues with people trying to replace the Magura brakes and Magura not making them anymore. Could be wrong on that but a friend of mine is having that issue.

Disc brakes are where everything is going. If you want to stay with rim brakes, that's fine. If you want to future proof a bit, go disc. You could use eTap with the P5 but Di2 would only be on the aerobar shifters.

---

That is part of my concern with the P5 and why I was wondering if they have a new or updated P5 coming in 2019. It seems that BMC, Argon, and Trek have recently updated their tri bikes and my assumption is that Felt and Cervelo (unless they are phasing out the P5 for the P5x) would be making some changes (probably disc brakes and hopefully aerobars that tilt) in the near future. If the P5 doesn't get an update I probably go with Argon 18, BMC, or Felt

Felt IA with disc brakes is rumored to be coming soon. Cervelo, who knows? The P5-X may have been the replacement for the P5 but I highly doubt it has been successful for Cervelo. I would bet they are designing a regular frame with disc brakes to come after the P5-X.

Trek...no idea on what they are doing or if they will add discs to the Speed Concept. I think they will but the anti-disc brake crusaders here will argue about that.

---

I think Cervelo would be well served by updating the P5. If they added disc brakes and tweaked the front fork and cockpit to a fully integrated system similar to Felt and Argon 18 I think it would be a big hit for them. It would probably seal the deal for me.

Then it's up to you to decide to wait for disc brakes or not. Personally, I think you should. However, you will face a lot of criticism on here for that decision.

---

Make Inside Out Sports your next online tri shop! http://www.insideoutsports.com/

 Only downside of disc brakes for me is I would have to replace my Zipp wheels which have my power meter which is an added expense. If I manage to sell my current tri bike and wheels I wouldn’t think twice about switching to disc brakes.

Well, decide on what path you want to take first. If it's disc brakes, sit back and wait. Then sell everything when you find what you want. I look forward to seeing the new IAs with disc brakes.

Are you in the market now or waiting for next years models to come out?

---

"see the world as it is not as you want it to be"

They will probably look a lot like the previous IA except...with disc brakes.

I expect disc to trickle down to P5 or P3 this year or next.

Definitely same IA frame with disc brakes.

---

Make Inside Out Sports your next online tri shop! http://www.insideoutsports.com/

I'm in no rush so I am essentially waiting to see what is available after the 2019 models come out and can decide. I suppose worst case scenario is I wait until the 2019's are out and if I like the 18's I get a better deal. If nothing changes with the Cervelo or Felt (I've seen the 19 Argon 18 and I like the 18's better) I probably go with the Argon 18, Felt or BMC.

I think its a great move.....maybe a 2019 or a good deal on a 2018. I have a Felt IA-10. If I had to do it all again and the Argon was available at reasonable price I would get that.

---

"see the world as it is not as you want it to be"

Most companies (Cervelo isn’t right now) are charging a premium for discs which is a potential deterrent for would-be purchasers

I don’t think people criticize those that want disc brakes. I think the criticism comes when you act like discs are somehow superior to rim brakes and are the better choice. It’s completely personal preference. That’s all.

Disc brakes on my next tri bike aren't really an issue for me. If it has them great (probably the future, better stopping) but if it doesn't (I keep my wheels and power meter for now and save some $$) that is fine. I would definitely want them on my next road bike for sure (better for inclement weather and hill repeats on the downhills that end on a busy road).

I just wish they would come out with the new models already. haha

Agreed and the prices quoted for the new Cannondale superslice are hardly seductive. Currently it seems like the QR PR5 disc is the most affordable and it has a silly premium compared to the rim brake version. Maybe when the open mould frames hit the market (from the likes of Planet-X and such) disc brakes will begin to become the norm, but I doubt the new Felt will be anything but top end.

A well designed Cervelo P2 and P3 with disc brakes would keep them dominating transition zones. I don't see the need for a new disc P5 once the rim brakes are removed from a P3 and a tidy front end is installed.

SteveMc

Yes. The Cervelo folks in Europe said that an updated P5 would be released this fall. The hint was disk brakes and storage. I LOVE my current P5 and I believe I'll be up for this new one. I would expect to pipeline to be flowing until spring.

Storage on a Cervelo? It's about time.

I would wait till after Kona.

Okay, i have just about seen most new dealerbooks. Felt IAx stay the same, just colour updates, the IA series, with the integrated front brake all go disc brake.
Cervelo lists P2 2 colours, P3 2 colours same frames as previous, P5 same as this year and P5X in a great new colourscheme. Looks really awesome. Have pictures from the dealershow right now, but won’t post them yet Rumours are a P3X disc, but nothing so far of a P5 disc. There is going some stuff released by september as they said which is not at the dealershow.

How long do you keep bikes? I think discs are still many years away from being universal. So you could easily get a new rim bike now and in several years see what the market is doing.

Wow. That would be really tempting for me. Don’t think I would be able to pass that up if they made those changes. If they added storage,disc brakes, and integrated the front end that would be the best case scenario for me. Haha

Although they did work well...I never liked the Magura brakes anyways...they were not easy to get set up on wider rims...even when you removed spacers...then the pads were hard to get flush.

I finally decided to go back to the p5 three...and glad I did. When I had my LBS check on a frame set...there was only one 56 left. Really happy with the build, I like the Aduro bars...I like the ‘18 paint-job...we put an ee cycleworks brake up front. I plan on staying on it for a while...

Not opposed to this idea as it saves me some money (dont need new wheels and power meter) and really disc brakes aren't a huge issue for me. Cervelo was one of the better fits for me so if they did update the P5 it would make it my choice a little easier.

How were the color updates on the Felt? Honestly, the colorways of the Felt are the biggest drawback personally. I know that is kind of silly but I'm not crazy for them.

It’s here. Only way to get single number IAs now.

Couldn't you just replace the brakes on the P5-6?

hi,
after a lot back and for I also consider going back to Cervelo. Initially I had something different in mind but after some excitement (and still lots of open questions but no feedback) I think I stick to what I have and know. If I get a good deal on a P5x and a good fit I'll jump on it.

Not really...as I had sold my p5 six a long time ago...😊

I was riding a P3 again...waiting to see what changes were coming...heard that there reallly wouldn’t be any...so that’s when we thought to look for the P5 three. My LBS sold the P3 for what I had in it...the same day I brought it in...they kept 20%, so it worked out pretty well for me...

And sorry to get off topic...

But one thing I always think about when I see these threads...why doesn’t the OP consider premier Tactical or Quintana Roo? I personally would buy either of those before I put money into a FELT

I don’t think adding storage and disk brakes to the P5 would make a ton of business sense for Cervelo. Given the similarity in aero and price, it and the P5x would eat too much into each other’s sales.

---

Matt

I’m not in the market, but good to hear. Not a fan of the P5x color scheme. Now the Lamborghini version, that’s a looker.

Do you happen to look at the R series? I really like the bright yellow color scheme of the current R3, so I’m hoping new ones come out so I can get it on sale. Also wondering if the will keep the R2 as rim only

---

Matt

I need to take issue with this talk of future proofing with disc brakes. Rim brakes have been around for what, 100 years? What parts would become rare or unavailable in ten years? TriRig calipers? Cables? Aero brake levers? Traditional race wheels? I’ll go out on a limb here and just say highly, highly unlikely.

So would a 'P3X' be a beam bike, or just a P3 with discs?

I can't promise whether TriRig will be around in 100 years, and I most likely won't be alive in 2118, but I would bet that rim brakes will still be here.

You should check out QR PR6 Disc. I am completely satisfied

I hadn’t really considered a Felt before but I was fitted and it was on the list that fits me which is the biggest factor in my decision. The QR wasn’t a great for and the Tactical was something we didn’t consider. I haven’t ridden a Felt yet but I wouldn’t buy one unless I had a chance to get one out for a test ride.

I’m really looking for a tri specific bike. I was hoping for a good update on the Argon 18 e 119 but I’m not a huge fan of the new color scheme. If I go that route I’d go with the 2018 look.

There are other bike releases still to come before that project.
I think that timeframe is excessively optimistic.

You can. I put the SW-R9150 satellite shifter to the bull horns, works perfectly. There is a dedicated thread here on ST regarding this topic.

Update: here it is:

Can't tell since I haven't seen anything, it is so far just a rumour that there will be a P3X. The P3 as in the previous year will still exist, but there seem to be just only 1 P5X so they might bring a cheaper version and call it P3X but like I said, it is so far just a rumour and I haven't seen anything in pics right now. And if I did/do I don't show them until Cervelo gives the green light for that.

How about a Canyon?

Hopefully a P3 with a clean front end, disc brakes and internal electronics. Having to have an external Di2 battery in 2018 in an expensive bicycle sounds...stupid.

Buy a $40 bento and put in there. Done nice looking and cheaper than what a manufacturer will charge for integrated version

There will be a S5 Disc, a new S3 Disc, and also P5 Disc.

I didn't understand if R5 would get an update as well (which would be weird since it was released just a year ago), but there are some hints of it or maybe the person I talked to didn't understand things properly.

They might all not come this fall, but likely still be available before next season begins.

---

----------------------------
Need more W/CdA.

Waste the bento area to hide the battery? Then store the gels/bars under the downtube?

Come on, no excuses, an external battery mount on the bottom bracket shouldn't be a thing in 2018 on a Cervelo bike.

I would say the same thing about using bars/gels in 2018.

Nice whataboutism. What about Cervelo having TT/Tri models which still attach their Di2 batteries externally, anything?

I’m being serious. I use my bento for blip box and tubes etc. I don’t understand in 2018 why you would use bars/gels and I think placing them ina bento is a waste of storage space but that’s just me. Personally I think integration is overrated but I understand what you are saying and I’m sure it is coming.

They built the P5x for people like you that use gels/bars. Maybe it will trickle down.

Can anyone confirm if the internal Battery Mount method on the S5 also works with the P3 & P5? See the S5 Manual, page 11.

---

---

Canyon was on my wish list but the fit/geometry doesn’t really suit me well. I’m still intrigued (but don’t think I would given the fit)but I’ve heard they have also had some issues launching in the US. A canyon road bike is something I would really look at though.

I have seen their new dealer catalog...there is no p3x...no P3 disc. The only change I saw was there also is no more p5 three...

True, but at the ongoing dealershow there is the blackbox where there are 'supposed' to be pictures in from some new models that are not in the dealerbook yet to prevend them from an 'early' introduction and these models will be revealed in September. Interesting thing I found in the dealerbook was that there mentioned P-X series and that most models were specified as 'rim' or 'disc' brake models in their names/series. Might suggesting that could be a P3 rim and for example a P3 disc.

Anyway, we will see in the weeks before Kona if there is anything tri specific new that they don't want to introduce yet :-)

---

Owner at TRIPRO, The Netherlands

Well...being truly secretive about it is one way to do it. Or they could have started some countdown...like 144 day count to ....wait, we need a do-over.

What do you use instead?

Lol what? Have you ever raced an Ironman?

---

Make Inside Out Sports your next online tri shop! http://www.insideoutsports.com/

What's wrong with bars and gels?

No. Is your question directed at repair aspects of my suggested set up or calories? What problem can I help you solve today? :)

This is personal....for me...(1) storage; (2) potentially messy; (3) having to deal with trash; (4) not personal to your nutrition needs (like infinit is); and (5) having to grab, open, mix with water etc while riding (as opposed to grab drink and go with calories bottle or just drink from straw if you use that type of bottle)

OK, yeah, I agree. Roadie now, but never ate on the bike on my two long-course tris.

I was just thinking as a roadie, I do cram a few gels/bars in my jersey on long rides. But that's a whole other deal, not racing, storage not an issue, etc.

I use bottles in calorie for long rides but often carry “back up” gels in jersey pockets. No aero penalty and save bento space for things I would prefer not to have/can’t have in a jersey like blip box, repair kit etc

Interesting, I expected a more TT orientated bike for Sunwebs use as they already have the P5x with lots of storage. I thought maybe a cheaper P5x might come out at some point as well.

As I just TT these days I was hoping for a rim braked P5 update along the lines of the British/cervelo Track bike.

I think the problem you’re going to run into is them making it any faster so should they really build new molds.

I love my p5 and I’m not expecting anything drastic beyond that anytime soon. I’ll just be pissed if the the brakes break as I love the hydraulic ones and don’t want to not have those as an option in the future

Am I missing something, I have built many of these bikes with Di2 including older generation and all with internal battery in seatpost?

Because science? Seriously, not all of our guts are the same, so not all of us can pack a bottle with 800 calories in it. Also, most of us don't truly have the time to care for making a custom formulation on infinit when we'd like to just gob down a gel of Gu Roctane Caramel Macchiato...also...let's talk about people who saran wrap home made bars to their bike instead, that has to be non-aero and just weird.

---

Washed up footy player turned Triathlete.

At risk of derailing the thread about P5, it’s custom so you can pack as many or as few as you want—you can “pack” the same number number of calories as you would take in from gels/bars. Custom process took me less than 5’. Infinit will do it for you.

Still prefer gels? Premix. Save time, storage, messsiness, trash etc.

Saran Wrap home made bars? Yeah that’s weird. I always thought sticking any bar/food to a bike to be weird and kinda gross.

Not everyone does liquid only nutrition. Storage is very important for long distance racing. Yes, I can fit some of my repair kit behind saddle and some in my bento with nutrition. But to say that storage is not important on triathlon bikes is just wrong.

---

Make Inside Out Sports your next online tri shop! http://www.insideoutsports.com/

when did I say storage isn’t important??? I said integration is overrated. Storage is very important. I just think that aftermarket storage often makes more sense.

My mistake. I guess I prefer all in one designed solutions instead of bolting on aftermarket things. But, that gives more choice so whatever works.

Don't cube use the Mugura's on the bike they old released this year?

I guess there are two ways of thinking about it going totally integrated with proprietary parts such as built in bottles or trying to best integrated standard options (e.g round bottles or after market aero bottles.

I think the Ventum and the Shiv did it right with integrated hydration. Combine that with an integrated bento and you have something awesome. Then you can carry a BTA bottle as well.

source?

why would you ever, ever use an external battery on a p series bike? i don't care what it comes with, why would you leave it like that?

I've tried a number of aftermarket bottle setups with straws and was underwhelmed by all of them. Chief among my complaints was the PITA of cleaning out the whole system after Gatorade baked in it for hours. Being a bit of a germophobe, complicated hydration systems like that just sort of creep me out. I'll take a regular bottle BTA and another behind the seat any day. Now, integrated storage - yes, please!

Are you able to install an internal Di2 battery on a P3? If so, why doesn't Cervelo?

Looking at a lot of their patents [specifically Specialized], that would be like saying Giant can't make a dual suspension mountain bike. There's a way for other companies to integrate hydration within the fuselage, they just have to figure it out.

1. yes, easily
2. you'd have to ask them

(although ktm is wrong the p series should have the internal battery in the seat tube, not seat post)

I have 3 friends with SHIV and all stopped using their integrated fuel systems.They may use it for that one day in their live, the long distance IM. And still than, you can carry up to 1.5l around..you still have to refuel somewhere. My issue is that due to my short arms there never fits a bottle system in the front. But integrated like Shiv is a no go for me. Reminds me on my first camelback. This thing looked ugly as hell after some months.
Ventum's system instead looks way more practical! But you loose all the storage capacities for that. I've seen people putting bentos on top of the water tank. Not sure if I would like that. there is always something..

If Ventum added a bento behind the stem and in front of the bottle, that would be super cool.

---

Make Inside Out Sports your next online tri shop! http://www.insideoutsports.com/

It has screw holes to add a bento...I'm guessing though that this is the same frustration with the p5 and p3...just put a bento and sell it that way in the first place?

Ventum has screw holes on the bottle, not behind the stem.

---

So you want holes behind the stem and under the bottle? You'll just make the bike slower by removing the bottle. It's literally designed so you have to have the bottle in place or that's the way they make it seem when they pitch: "It's the only bike out there where it's faster with the bottle than not".

I am very familiar with the Ventum. I played with it at the A2 tunnel and my shop carries Ventum. I said take the bolt holes off the bottle and put the bento behind the stem.

No worries and understand the point yet still prefer the seatpost even with travel. I am likely not the best resource for the other posters protest as I do not necessarily expect the manufacturers to come up with ever solution for every client, I just do not want barriers or major limitations for customizing.

The P5X is the update from P5. The whole concept was built about creating a disk brake, faster, stiffer and a full solution for carry stuff with it.

I came from Felt IA to the P5X and couldn be happier, bike is agile confortable and climbs way better than the IA.

Regarding having the di2 changers on the base bar with the P5, your local bike shop may be able to adapt it, seen a lot of it around.

No it isn't. P5 is ITU legal p5x is not. Cervelo has to keep the p5 in the line or update it.

A person I happen to know, who recently visited Cervelo European HQ

That said, as far as I understood from that person, while S5 Disc is sitting in a special room already, waiting to be released for the public, that can't be said about the P5 Disc, so it is still possible that regarding the P5, something was lost in translation.

It may have been ready as early as the Tour of California from what I understand. Unclear what the reason for not unveiling yet is. I’ve got a few theories as to why:

First is current S5 inventory, lots still available, and very slow to move. Maybe this bit of time will let that dwindle down a bit.

2nd is ending partnership with Dimension Data, they probably would have owned those bikes and they wouldn’t have been of use beyond this year.

3rd is Cavendish, maybe he didn’t like the bike, maybe Cervelo didn’t want someone who wasn’t likely to contest sprints at the tour giving it its first bit of exposure.

4th is that there were lots of other bikes unveiled, which maybe means there wasn't a way to put together one of these media weekends for journos to test ride the bike and write about it.

Looks like Cervelo just released the 2019 bike lineup. Updated P5x, P2, and P3 but no changes to the P5. Too bad. (for me i guess). I was hoping to see some changes to the P5 (replace the magura brakes for anything and maybe some storage, and a new colorway) for my next bike. I'll have to take a closer look at the Trek,BMC, Felt, and Argon 18.

yep. I wish Specialized would hurry up

---

Make Inside Out Sports your next online tri shop! http://www.insideoutsports.com/

I'm waiting on Felt. I hope they do something with the colorways of the IA. Almost time to go test ride some bikes.

BryanD--I checked out insideoutsports.com and noticed you carry Felt, Cervelo, and BMC--if you dont mind me asking how would you compare the ride of the Felt IA and the BMC Timemachine, and P5?--I had intended to purchase a Cervelo when I bought my road and tri bikes but both times after riding a different bike I ended up not getting the Cervelo. I went with a Pinarello for the road bike and a Parlee TTi for the tri-bike after test rides. I've recently been on the speed concept and it was good and comfortable but didn't strike me as overly comfortable or overly quick.

Never ridden any of them. I have a 2011 P2. The shop owner has a P5 and an IA and likes both.

---

Make Inside Out Sports your next online tri shop! http://www.insideoutsports.com/

I would question the idea that the frame has any perceivable impact on comfort or that there's any value in a test ride. Test rides don't typically test the frame, they test the exact setup of the specific bike you took out on that specific day, in the specific location and weather you rode it in, and also tests how you're feeling at the time and perhaps your preconceptions about the bike.
Seriously, minor fit adjustments, choice of tubes and tyres, choice of saddle, type of bar tape, even things like brake and gear selection and adjustment, almost certainly have a far greater impact on how you judge the "comfort" or handling of a bike. Since most of these are dictated by someone else and not as they will end up if you buy the bike, it seems ridiculous to me to even do a test ride. Incidentally, I put my money where my mouth is and bought a Canyon road bike 4 years ago without ever riding one, or even having even seen one in the flesh and would happily do so again.

I really would like to know the rationale of test rides except if the bike is in some way novel.

I find the value in a test ride allows me to see how a bike handles, the stiffness, how it handles vibrations from road and the overall comfort as it relates to the bikes "ride". The position as determined by my (or anyone's) bike fit is one thing but how the bike handles the road can be different as a result of different factors including the type and quality of the carbon fiber used in manufacturing along with the placement of seat stays etc. For example, most cars "ride" and handle differently so people take them for a test drive. It is was only about "position" all you need to do is sit in the drivers seat to see if it was comfortable.

I admit a test ride isn't necessarily needed but if the option is available I try and do it. Not to mention--it's fun to go for a ride on a really nice bike.

I don't agree for the reasons I previously stated.
I would be astounded if the frame properties can be differentiated from the other factors I described for any well designed and built bike. The noise massively outweighs the signal. I believe it's purely a psychological thing and has no objective merit. Do you check the tyre type, size and pressures, bring along your own saddle and use the same bar and bar tape for every test ride? Do you test them on the same roads in the same weather conditions. Each of those will almost certainly have more effect on your physical perception of the ride and handling than the frame. The car comparison is not particularly comparable. However, I would say that for cars, you're really testing the interior environment, the feel of the gearbox (if manual), the power curve of the engine, the gearing of the steering, the tuning of the suspension, the visibility, the fit, function and familiarity of the instruments. Most of these do not apply to bikes where you are the power source, the contact points are commonly changed for personal preference and not a purchase factor (saddle, bar tape, pedals), the suspension is almost entirely dictated by a consumable and easily adjusted part (tyres), and steering, visibility and instrumentation does not really change by bike.

So what is the purpose of the test ride? IMO it has none, since ride and comfort are not primarily determined by the frame and cannot be usefully compared by a rider, especially when riding differently configured builds, at different times, on different roads, in different weather.

They have only released the 2019 carryover models; those that aren't materially changed from last year. It has been leaked that they have 3 "new product" announcements to come later this year. Wouldn't be surprised to see at least one new tri-bike announcement at Kona, and maybe two. They've left a huge hint on their website that some sort of disc brake P-series (non-X) is coming by labeling the 2019 carryover p2/3/5 as "Rim" models. There have also been rumors of P3X.

---

"They're made of latex, not nitroglycerin"

Amongst TT frames you won't be able to perceive a difference in ride quality. They are all incredibly stiff in the vertical plane. Any differences you feel riding one are down to the tires, air pressure, quality of the road, and padding on the saddle and armrests.

As an FYI, the Speed Concept and P5 are basically the benchmark frames. You're not going to find a bike faster than either (at least not meaningfully and certainly not from their piers of the same vintage).

I wish everyone understood this... may copy and paste this, with permission :)

With regard to the 'comfort' of a bike, I agree with you 100%. However, there are still certain things that I'd want to validate in a test ride. Here are just a couple of examples:

1) Let's say I'm debating between a P5 and a P5x. We've already heard how some of the top pro's chose the P5 over the P5x for IM France due to the hilly course and the fact that the P5 ls lighter. I'd want to ride both bikes on a hilly course to get a feel for the acceleration and climbing differences between the two bikes.

2) Last year I was looking for a new 'training-only' road bike. I was looking at the Cervelo C5, Trek Domane, and Specialized Roubaix. The Roubaix has the 'future shock' thing going on, and the Domane has the Isospeed decoupler. The C5 is a much more 'traiditionally' built bike with very thin seatstays but no other 'gimmicks'. I wanted to see what effect these things had on the bikes. Long story short, I was not a fan of either the Isospeed decoupler or the future shock - both made the bikes feel more 'sloppy' (yes, that's my technical term for it). The C5 had all the comfort of the other two (due almost entirely to the 28c tires) with better handling and without the gimmickery.

There may well be differences between bikes, such as weight as you mention here, that are worth considering. But I still maintain that a pre-purchase test ride is not a useful way to make judgements between bikes. I'm very sceptical that there's anything useful to be learned in your example. You're not going to be able to discover anything about the impact of one or two kg of frame weight on performance simply by riding up a hill "to get a feel for the acceleration". Indeed, I'd say acceleration isn't much of an issue anyway for climbing, it's the effect on average speed that matters and that's probably best determined mathematically - do a simulation on Bestbikesplit for the lighter bike and then increase the weight to the match the heavier one and run it again. That'll tell you what you want to know surely?

Hello guys !
Be patient, and enjoy ;)

You should have been to Germany last weekend. Cervelo belongs to the DerbyCycle Group (Pon Holdings). They presented their latest bikes in Cloppenburg at their very own exhibition were they were also showing three updated bikes featuring disc brake and new designs. In your case I would be patient until Kona this year. There "might" be a classic shaped diamond triathlon bike with disc brakes together with a very unique cockpit solution (mono-stem). :)
They "tried" to make it as top secret as possible but for sure some people were able to take some pictures. I hope someone will post them here.

I have pictures, but sorry i won't post it here.

They only seem to sell the non UCI legal version for the P5 now. Some big names riders on dimension data wete riding P3's at the Tour as that's the highest model UCI bike they now sell. Big shame as the P5 /3 is arguably still the quickest uci bike.

Given the P5 seems to be the only bike rocking 2018 colours I guess it's days are numbered. As they stopped producing the P5/3, I am guess the current world TT champ will be on a new cervelo TT bike next year. I looks like it will be disc bike from all the rumours. So for those not wanting to make the move to disc brakes yet the P3 will likely be there top option.

Have yet to see a disc brake bike at a UK CTT event (most course only have the odd roundabout to manoeuvre!), so not sure this will get huge buy in here over current popular bikes among the fast guys & girls: Giant Trinitys, Trek Speed Concepts, Scott Plasma 5's, Cervelo P5's.

Thanks for the value added post!

P5X is ITU non-drafting legal, as the P3X. It's listed on the Non traditional or unusual bikes approved to be used in ITU draft illegal competitions:
