All around with latex is this still the go to don’t overthink tire? Or is it the 5000/corsa 2.0?

All around with latex is this still the go to don’t overthink tire? Or is it the 5000/corsa 2.0?People I know that have switched to the 5000 seem to really love it. I’m guessing that’s mostly based off of handling / cornering and ‘feel’ but not durability since the tire is just too new to really know. (All are bike racers who use it for racing).
The 5000 has relegated the 4000 to just being a great all around fast training/B race tire. The 5000 is slightly less aero, but is better in about every other metric. I have been training and racing on a set on my road bike all year and they give you the tubeless option as well.
Corsa Speed 2.0 is pretty much reserved for racing. Other than having a super low Crr that generally makes up for being a bit of an aero turd, it has few redeeming qualities. Still aLmost impossible to beat in a straight line.
Nothing to add besides that I ran 5000s tonight at the Pterodactyl. Looks like you and I both dropped some time from June. I also ran 5000s in June, so I guess nothing pertains. Nice job though!
I don’t get why the tubeless version is only 25 mm and lager, No 23 mm. Does anyone know If I can run those 25 mm tires on my hed jet blacks and not ruin the aerodynamics of the wheel?? I usually hear on slowtwitch that you should not go more than 1 mm wider with my tire than my wheel or i start to ruin the aerodynamics of the wheel. I put the 25 mm on my Flo disk and the measured just less than a mm bigger so I think I am o.k. on the Flo disc, but I am sure it will be more than a mm wider on the hed 80s with the internal width of 21.
For what it’s worth, the 23mm GP4000 was a BIG tire. I forget my measurements but the difference between a 23mm GP4000 and a 25mm GP5000 is <1mm on Jet+ rims.
Just a side note but the gp4000 “RS†I believe was the predecessor to the 5k.
It measures truer to size like the 5k, and also rolls better than the 4K.
25mm 4K is right at 30mm on enve at 100psi. The 4krs and 5k both measured about 3mm lower.
Haven’t mic’ed out a set of 23s yet. I think that if the 23 4K is the standard for the front then the 23 4K RS might be better??

GP4000 in 28mm couldn’t fit on my Roubaix! Switched to Victoria Corsa G+ and there are no fit net issues.
Depends on usage, price sensitivity and whether you’re running tubeless I think. 4000s are a fair bit cheaper than the other 2 at the moment, still a great tire, only give up a few watts to the 5000 and may be slightly more aero and puncture resistant. So for everyday use they’re still a great tire that is fast enough to race on, resilient enough to train on, and won’t break the bank. I run them on my road bike for these reasons and will likely do so for the foreseeable future.
If you want a tire mainly for racing, then a few extra watts are likely more important to you, and a few extra $$ less of an issue as the tire will last a lot longer anyway with lower mileage. In which case the Corsa is the fastest but the most fragile and most expensive, 5000s are a happy medium. I have 5000s on my TT bike.
If you’re on tubeless (I’m not) then the puncture resistance may be less of an issue as sealant helps on that front.
Movistar were using the GP5000 tubeless in the tour
I think that gives you your answer.
With all the variables weighed up I can’t see past the 5000 for long course triathlon
As long as it’s cheaper than the 5000, it will be THE tire for me. I have no desire to spend more money on a pair of 5000’s. They seem to be quite a bit more expensive? Convince me otherwise slowtwitchers!

I’m still on GP4000 but I’ll probably switch to GP5000 next. Cheapest I can typically find GP4000IIs is ABOUT €36. And these guys have GP5000 for €40.61
When the delta is only about 10%, I won’t decide based on price. If it was a much bigger extra cost… then I might.
IMHO, it is the Continental GP 5000 now. I am already running 25mm GP5K tires on my road bike, and I love them. Maybe it is psychological, but they feel more comfortable than the GP4K2 tires I had on my road bike before. No clue if they are faster. My next tire purchase will be a set of 23mm & 25mm GP5K tires for my TT bike.

Team sponsorships are a terrible way to decide on equipment choices.
Just my 2¢.
Except when they choose it over other continental tyres.
In that case it’s valid.
Congrats on a faster time. I’m Surprised I even raced. Had the runs mon/tue and had a slight fever Tuesday night. didn’t feel good at all pre race but once I swam a few minutes I felt great! Was thinking about getting a pair of 5000’s for the last race of the series. I love this series and have really started to focus on it more that I have a one year old.

Fair enough.
But we won’t know whether that tire shape just (aero) pairs better with the Campy wheels they run or for other reasons.
Looks like the Conti 5000 in theory is one of the best all around racing tire now.
However, for some reason, the 4000’s “feel faster” to me than the 5000; Hard to explain, the 4k’s feel more “supple” and that have a “hissing” sound when rolling that I got accustomed to in the years racing on them. This is missing on the 5000;
But nothing I can actually measure. So based on published results, I am going with 5000’s current and on future racing tire purchases for improved rolling resistance, running them w latex tubes. Upsized to 25mm on the 5k’s compared to the 23mm I was getting on the 4k’s.
I did have one of each yesterday (5000 in back, 4000 out front) at Pterodactyl, but just happened to be what was on these race wheels.
For the power I put out, my time did not compare extremely well with several past results (2nd highest power, 8th or 9th best time) but there was a lot of other factors at play including a different frame (still an SC with same aero position)…
p.s. I raced for a while on turbo cottons and a season or 2 on CorsaSpeed… felt fast (and had good splits) but felt too fragile and not lasting at all. After a few races, they were done.
I feel like the conti’s I last very long in comparison, then when done racing them I can re-purpose them as training tires or even for my trainer in the winter (still a computrainer user). So I get a lot of value out of them and it makes up (in my book) for the fact there might be slightly faster option out there.
How much slower was your bike? You averaged over 26.5mph, right? At that crazy speed I wonder how much could be cornering, mount/ dismount, etc. Very impressive riding!
Thanks! Here’s my time history for the strava segment of the bike course (clipped in sections); So 19 seconds slower than my best last August despite very similar power. Of course, weather and traffic conditions are a big factor.

So this was only my 9th or 10th best time despite being 2nd highest power.
Looking at the comparison between my PB and yesterday, looks like the wind direction was different: loosing time on the way out, gaining on the way back, but I did hit a rough patch after passing the front group of 3 (“X”) and started to lose time again; Then at the corner of the park entrance, line of cars waiting at the stop, had to brake a lot to squeeze in the 1.5 foot wide space left and lost another 5-6 seconds compared to taking the turn at high speed.
