Hi Damon; have three questions:
Like many others i have to choose between different sizes :
- is the difference between Low and High V just additional part? ie can i convert HIgh V to Low if i need to. (If its molded carbon there can be a problem with packing the bike for travel)
- did you wind tunnel test the fork spacers - i know u say aeromatched - however what would be a aero penalty for using those vs using High V (read High V tested
- never used hydraulic brakes - is the system sealed enough for it to travel well? Ie for an average luggage handler
appreciate the insight

Hi R2,
Yes, just a different part. There is one base bar. Either you bolt on the "Low" piece to hold the arm pads and extensions, or the "High-V" piece. Some 4 bolts either way. Arm pads and extensions attach to the additional piece, be it Low or High-V, not to the base bar. Both Low and High-V parts are included.
Yes, we wind tunnel tested the spacers. No difference.
The hydraulic brakes use the same hoses and connections as Magura's other hydraulic rim brakes. These have proven reliable for decades on city bikes. I think they'll survive air travel - none of the brakes on the P5s we've flown to various Brain Bike events have been damage in shipping.

Hi Damon,
Have you guys started shipping the P5 already? I will be in Florida (I live in Argentina) early May and I have contacted one of your authorised dealers who told me that there could be delay until late May. Is this true?
Kind regards and thanks,
Jorge.

Hi Jorge,
Thanks for considering a P5. We haven't started shipping them yet. Your Cervelo dealer and their rep have the best information on delivery times.

My LBS mech might have something to say about that statement.
In his comprehensive experience - he sees them every day - the Magura brakes as fitted to city bikes in Germany are most definitely not reliable.
I sincerely hope the Magura technology on the P5 lives up to your high expectations. Although, going by the rear brake reputation of the outgoing P4, stopping the things doesn't sometimes seem to be top of Cervelo's priorities.
That last sentence need a pinkish font.

So then why have all orders that were placed for them at booking time in Canada been pushed from what was originally May, then June now September? I've read the letter the president of Cervelo sent out to the dealers and he states that because of the purchase of Cervelo by PON that Cervelo could not buy any materials. I even saw it somewhere that any orders not in the system by booking time will be considered priority for 2013, talk about missing the season. I had one on order and am questioning if I want to leave my order standing or go back to the big S. I even have a S5 team with Ultegra Di2 that I'm still waiting on, guess I shouldn't have sold my other bikes early but I thought Cervelo had the best distribution network going and I would have them quicker than this. That's what made Cervelo number 1 in all the bike counts, people could get them. it'll be interesting to see if the bike counts numbers change this season or next with this.

And remind me again what the point of bitching at a senior engineer of r&d is about availability?
If the time necessary to input on their products on these forums gets too mundane and too time consuming its unlikely in the future that we'll get the chance to hear from these high up guys in development. Instead, at some point ST will receive responses by "John Doe" from customer service.

I wasn't bitching, I was wondering why everybody is still waiting. Beleive it or not I'm not even really that mad about it, I'm more concerned with getting my S5 right now and I'll use that for tri if I need to.
But if he will answer questions about anything Cervelo people feel they can ask him questions. Sorry of my post came off as "bitching", it was never meant to be.
There are a lot of people who are really pissed about the P5, shops included I'm sure. They placed orders last fall and won't receive them till after the season is over this year. Kinda tough to sell a $10000 when the season is over and fall is almost here. When mine was ordered it had a ship date of June, now September.

I was in the market for an S5 and had a bike order placed with Cervelo and they kept pushing back the delivery date. Ultimately i ended up getting the white S5 frameset and built it up to my specs Di-2 etc...But from the day i ordered till the day i got it was 3 months. they kept telling me and the lbs something different every day. although i was pissed that it took so long to get the bike they came through and still honored the buy 2 get $2k off even though it was past the date.

You ordered a bike that isn't yet available, from a company that is known for slipping deadlines, without having a backup. You gambled and lost. Switch your order to P2, or ask for your deposit back and buy a used P3 or P4 from the classifieds.
ADMINS:
I think we should split out the posts complaining about the delays into a separate thread (not censor them), and leave this one for technical questions about the P5. It's great to have Damon here answering questions and it's foolish to waste that opportunity by allowing this thread to spiral into a bitch fest.

Hey Krau, I'd suggest deleting your post.
First, there are rules to this forum; one of which is: "Do not register to post on this forum only to have your first post be a complaint against a company doing business in the sport of triathlon."
Second, ALL major triathlon companies have had some delays with a new model in the last 4-5 years. You were ignorant to think that this wasn't a possibility.

Oh I don't know...the "official [brand/model] thread" concept is pretty helpful IME.
Sure, there will be folks who see what they want to see (
this one was funny
), but on the whole the positives really far outweigh the negatives...both in the tenor of posts and the convenience of one-stop-shopping for Q&A. I mine the SC thread for answers myself sometimes :-)
As for spiraling, the depth of the spiral is directly proportional to the speed-accuracy-helpfulness of the response. Between Phil, Gerard, Damon, and a couple others who've made appearances in this thread I think they've got nothing to worry about on that score.

Long time reader, first time poster and I think this is a good time to introduce myself. My name is David and I work in Customer Service for Cervélo.
I am fortunate to work with guys like Damon and it is great that he shares his wealth of knowledge on this forum. While I am sure he will continue to share his insights, I am happy to make myself available to anyone with a service or availability type of question. Feel free to PM me. Please keep in mind that I will not be able to track down all individual bike orders or exact ship dates.
As far as delayed deliveries; we are in full production on all models. We have started to deliver albeit in smaller quantities than what has been ordered. The demand for our 2012 models has greatly exceeded our initial forecast for the season. Increased production means longer lead times. In some cases, we may have pushed it too far to get the bike under the rider in enough time. I apologize to anyone who is in this situation.
We are making some key changes to our supply chain to avoid these delays in the future. Cervélo is in a stronger position than ever to deliver our bikes to more people. However, we will not see the effect of these improvements until later this year.
Sorry Runless, but John no longer works for us....

first, we didn't delete the post. the person who wrote the post deleted his own post.
second, i saw the post, and didn't delete it because it was so silly on its face and it seemed to me instructive to those who are naive enough to expect, and rely upon, spot-on-time delivery of a highly technical product that hasn't been produced yet at all. not just because the company in question may experience delays because of its own miscalculations, but because so many things can go wrong. heck, once i had a container fall off the ship. it's on the bottom of the ocean right now. that product you were waiting for.
cervelo is a gift to triathletes. if god came down and gave this sport a gift, it would be in the form of that company, for everything it has been and everything that flowed from it, in the form of bike designs by other companies that have had to hustle to match what cervelo has offered over the years.
cervelo has made one mistake. it decided to own its own pro tour, or euro continental, team, banking on landing a non-endemic title sponsor, immediately before an economic crash that was very difficult to predict. it gambled. it was a shrewd gamble. it was a swashbuckling gamble. and in the end it was a good gamble that didn't pay off. anything bad that has flowed since that time is because of that gamble.
otherwise, from 1996 'til today that company has done nothing but over-perform, and the s5 and p5 are the most recent examples of that.
i could write the same thing about trek/bontrager, and specialized, and some other companies, because we're in this perfect storm of great companies engineering from a position of strength. when one contrasts that to construction, banking, automotive, we have a lot to be thankful for.
that's the landscape, and it's through that prism i read the petty complaints. what damon started on at trek, and has continued at cervelo, and what carl has continued on with at trek, are really extraordinary. likewise what mark cote has accomplished at specialized. and dave koesel at felt. and they're all on this forum board explaining their designs to you, and helping make their bikes work for you. it's a pretty good time to be looking for bike product that works for you in triathlon. if you can't find what you want, at the time you want it, it's probably the mechanics of your search process that are flawed.

Damon, my question applies only to 48 [650] size. I own both a P4 and P3C and they fit me perfect, both are 650. I am ordering a P5 in 4 weeks when I get back to MIchigan. I known they will not have a 48 or 51. So I would like your input. My concern is the top tube lenght P5 476 to my P4 490. I want the same set up on the P5 as my P4 .With all the stack and reach questions I am a little lost on the actual top tube lenght. How much real diffence is there between the 2 bikes pertainning to the top tube. My concern the is P5 top tube is to short. I have always been on 650 bikes being 5'5 with a 29 inseam. Right now on my P4 my elbows are on the rear of the pads on the 3t. bar. Any Input will help... thanks

David,
your participation is a sign of excellent customer service. Thank you very much for it! I particularly appreciate that you give a detailed view of the current status. I can certainly understand the unexpected issues you describe. A somewhat positive problem from your perspective, I suppose. :)
My P5-tri was ordered in December 2011 so I'm hoping I'll be fairly high in the delivery list. However, my dealer told me that (at least as of now) Cervelo is unable to deliver a complete bike and offered to "downgrade" my order to framekit (which I did).

December!?! But we didn't launch it until January! You must 'know a guy'.
All kidding aside, this does touch on one of the biggest challenges for us in the development stage. We would love to have our warehouse full of the new model before we launch it so there is not wait for our customers. But, our approach has been to model, test, test again, test some more and then go test it 100 more times. A big part of that testing process is actually riding the bike. Naturally, there will be 'leaks' or spy photos and plenty of speculation and the clock starts ticking.... Even our own employees start anticipating new models, looking at the race calender and hoping that we might get a 'leg up' but riding something faster. As much as it might cause some frustration, this anticipation comes from the root of why we do what we do - the desire to get ahead and stay ahead.
And yes, in the early stages of delivery, getting a frame set might eliminate some of the supply chain complexity and possible causes for delay.

Hi rhudson,
Glad you like the fit of your P3 and P4 (and thank you for paying my salary! :-). You're right about not having a 48 or 51, those are among the last sizes produced. Of course it would be ideal for you, but madness for any bike company, to start with sizes other than the ones in the middle of the bell curve.
Anyway, to transfer your fit coordinates from your current Cervelos to a P5, just measure the arm pad stack & reach of your current bikes, then find the P5 frame size and aero bar configuration that matches those fit coordinates. This is all explained in the PDF linked at the bottom of the geometry tab of the P5's web page on cervelo.com. Here's a direct link:
http://cervelo.com/files/stackreach.pdf
Let me explain it below. Forgive me if you've already done the following, I'm not trying to be condescending assuming you haven't, but others are also reading so it's still worthwhile for me to write it. If you have done it, and just want to know about top tubes, then skip ahead.
What size P5?
The two-page PDF has illustrated instructions about how to measure your current bike's arm pad stack & reach on page one, and a handy look up table on page two. Follow the instructions on page one to measure your old bike and calculate your current APS & APR (note: we measure APR from the center of the BB to the center of the arm pad; some others use the nose of the saddle or the back edge of the arm pad). Once you have APS & R, then look at the table on page two. Page two takes your APS & APR as inputs, and gives recommended P5 sizes as outputs.
Follow these instructions when using the table on page two:
Step 1. Look for your APS in the left column (vertical column for the vertical coordinate, arm pad stack). Find the row that most closely matches your APS. For Team Garmin-Barracuda pros, I often print out the PDF and highlight the row.
Step 2. In that row, look horizontally to the right for the range(s) that include your APR (horizontal coordinates, APR, are listed horizontally). There are usually several size P5s that include your APR. The numbers in each range represent the minimum and maximum arm pad reach for each frame size and handlebar. The arm pad reach is adjustable in three positions: aft, middle and forward. Each one is a 25mm step, so you get three choices: the smallest APR (listed), the middle one (not listed, but it's in between), or the largest APR (listed).
From your description of your elbows on the back edge of the pad, you might find you'll use a longer APR setting, to move the pad forward a bit. If you measure APR directly, then you'll see in the table the range of APR you can get on a P5, and have the choice to put your arm pads where you like them. Then things like stem length & top tube length become less important.
Step 3. Look upward to find the recommended combination of P5 frame size and aerobar configuration (X-Low, Low, or High-V). On Team garmin-Barracuda I circle the frame size and bar.
Step 4. Determine the number of fork spacers. In the cell corresponding to your APS & APR, count the number of entries below yours. Each is a 5 millimeter step in fork spacers. The bottom entry has no spacers, the next one has 5mm, the next one 10mm, etc. Just count by 5s from zero up to your row. If you've measured carefully and used the table correctly you could literally install precisely the number of spacers indicated and know exactly what your APS & APR will be.
What about top tube length?
The P5's frame geometry is derived from the P4 & P3 geometry. Here's how we did it: We added 25mm to the head tube, driving frame stack up by 24mm and frame reach back by 8mm. (This is where stack & reach don't tell the whole story: the P5 top tube is not functionally shorter. Adding head tube length is the same as adding fork spacers: They both move the top of the head tube up the steering axis which is inclined, not vertical, so they both have the direct effect of decreasing reach ... but not top tube length. Just like adding fork spacers on an existing bike doesn't change the top tube length.)
That's the only change that affects rider fit, and if you use the Aduro bar and follow the steps above you don't need to adjust for any of this: the aero bar has a wider range of adjustment than most typical bars and can usually absorb the P5s higher frame stack. If you use a standard stem and bar, just take out 25mm of stack somewhere and you're good (Fork spacers? Stem angle? Arm pad spacers?)).
Then, keeping frame stack & reach fixed, we lowered the bottom bracket (compare BB drop in the
geometry table
) and designed a new seat post with wider range of seat tube angle adjustment. But BB drop doesn't affect rider fit, and obviously a wider range of seat post adjustability means your current position can easily be achieved.
Hope this helps, again sorry if it's too much info for your situation. Let me know what other questions you might have.
Cheers,

David, a long delay from announcement to shipping is not so much the issue. When it was announced:
http://www.cyclingnews.com/...-the-time-trial-bike
it said, on 18th Jan, "Cervélo have also confirmed the prices of the P5, which
will begin shipping next month
"
It's just hard for people to understand how "next month" turns into "in 8 months", though I think perhaps things look worse here in the UK, because it may never have been planned to send any bikes in this direction in the first few months of shipping.
