You might want to look at the actual rates of acceleration that occur in the systems under consideration. They’re… Not very significant. Small enough that on a bicycle, mass is, essentially, just mass.
Agreed. Compared to a 150lb+ bike and rider its almost non zero. Almost. Can’t help but wonder when you lose those sprints on bike throws if a lighter wheel would’ve helped.
They really easy to mount (with inner type). I tried to get it tubeless and don’t get it pop and seal. So I use it with latex inner tyre
Just replying to last to comment we have a new player! The Goodyear Eagle F1 Superport R TLC is a dead even match with the GP5000S TR at the 28mm level according to BRR. So another great option for a fast tire with some flat protection.
I am using the Corsa speed for 2 years now. Never punctured and do 2500 miles with a set of tires. Very fast tires
Are Vit corsas easy to mount ? I find Michelin power TT and power cup easy to mount but GP5000 is just brutal to mount on my 2014 zip and head alloy wheels.
With all tires it entirely depends on the wheel. Warming up all tires helps. On Firecrest Zipp 404 and 808, a 10yr old can install them blindfold with one hand. They go on like butter.

Huh. Interesting edge case.
I haven’t seen any data at all on rate of acceleration during a bike throw, but could be!
I love the Michelin Power TTs. Available in 23 or 25mm. Very fast. Surprisingly durable in my experience (been my race tire of choice for 3 years now).
Hey gang, back off of an extended hiatus.
Rather than start a new thread, I’ll tag on w/ my Q’s here.
Thanks in advance to any and all tire gurus who chime in!!
I’m in the market for tires for my TT bike - Cervelo P53, with 23’s,
and also for my aero road steed - Spesh Venge Pro Disc, which has 26’s on it currently.
On the P5 - I have been running Conti 5000’s (and prior iterations) for a decade now.
(Have had 1 flat during that time, which I doubt any tire woulda survived intact.)
Use latex tubes, was always Michelin, then Vittoria, now Silca.
Do I just keep on keeping on?
Or would the Michelin Power TT’s be an upgrade in terms of speed?
For the Venge - it came with Spesh Turbo (NOT Cotton) 26’s on it.
They’re… fine.
Have been pretty durable, but have a bunch of nicks and gouges, so it’s time to replace them.
Have run them with the Specialized light butyl tubes, because I’m lazy.
So - I’m thinking to switch those over to Conti 5000’s in 25, which IIRC in real life are actually pretty similar in circumference to the Turbo in 26.
And switch to latex tubes, because - duh.
I’m about 97% sure I don’t want to try going tubeless on this bike.
Not sure if the ROVAL 64’s that it came with are easily convertible to tubeless, or not.
Anyway - appreciate any and all input and feedback on these options, or any others I may have missed.
Ride on-
ML
I agree with the desire not to go tubeless. Easy to change tires with latex tubes. I just put on a set of power TTs and they were so easy to put on. They are really light to put on too. I have butyl on them now but with how easy they were to mount, switching to latex will be easy.
I just put on a set of power TTs and they were so easy to put on.
Though to be fair, while there were issues in the past, most latest-gen tubeless tires seem easy to put on too.
I’ve been using Conti 5K TRs and V. Corsa Pros recently, and they pop on with easy thumb pressure. This could be modern rims as much as the tires (I’ve been using latest-gen Hunt). The deep middle channel in tubeless wheels, if used properly, makes installation pretty darn easy.
I have not yet tried the latest generation of Corsa Speeds…those used to take some effort to get on.

I just installed a set of those. I was dreading it because of how hard they’ve been in prior versions, especially v1, but they went on fine.
I’m following this because I am probably highly overdue to reevaluate my TT tire setup.
Currently running 25mm/23mm Continental GP 5000 tires with latex tubesWheels are rim brake HED Jet Black that I could convert to tubeless, but I probably won’tI put very few road miles on the bike outside of a race (usually just 3-4 shakeout rides in the weeks leading up to the race)I love the idea of the GP5K’s reputation for durability alongside its speed, but I’m not sure I have ever even put that to a test
I’m super curious if there is a modern tire combo that is materially faster with also some durability reputation points.

This is me too, exactly. The Power TT seems to be about the only true contender.
Conti’s have been so “set it and forget it” for me for sooooo long.
But, I am willing to swap IF there’s a tangible improvement in speed, without a ridiculous giveup in terms of durability / fl_t protection.
The roadie should be an easy decision.
The Spec Turbo (not cotton) rate pretty ‘meh’ in terms of RR and aero.
The other Q I have is - my Venge can take a 28 in R, but it won’t fit up front - so that will need to be 25 or 26 (brand dependent).
Is there any benefit to running a bit of a ‘mullet’ and running a 28 R, 25 F?

Potentially a little better rolling resistance from the rear and better aero in the front. I run a 25/28 combo and this my general recommendation unless the wheels are specifically designed for 28’s. Parcours is one that is for instance and is marginally faster with a 28 v 25.

I ended up going w 25 F 28 R.
The Conti GP5K 25 is noticeably slimmer than the Spec Turbo 26 it replaced. That’s… a mild bummer.
And oddly, the 28 R tire doesn’t seem appreciably larger than the Turbo 26. < shrug emoji here >
In retrospect, I think I maybe coulda run a 28F tire after all, but what’s done is done.
Took it out for a spin last night, and I do think the latex tubes (yay Silca!! LOVE their extenders w/ the valve moved to the outside) make a difference.
Weird looking down and seeing a skinnier tire up F, but I’d imagine it’s maybe a little more aero that way.
Wonder if that offsets any gain in CRR due to the tire being a little less wide now?
Thx all for the help.

Honestly as long as the roads are not some sort of cracked chipseal hell, the 25 will be essentially tied with the 28. Your setup should be plenty fast!
(…) if you aren’t going to run tubeless, I would go with the Corsa Speed. It is the only fast tire with a puncture belt (that I know of), though I am not sure how effective these actually are.
I’ve been training and racing with a mix of Vittoria Zaffiro Pro and Corsa for ~4 years, and let me tell you that’s been close to one year and a half that I haven’t had a puncture. Since I switched to them, I think I’ve had 3 or 4 punctures, and I regularly cross short gravel tracks and very bad roads on them, these tires are really reliable.
I agree with the desire not to go tubeless. Easy to change tires with latex tubes. I just put on a set of power TTs and they were so easy to put on. They are really light to put on too. I have butyl on them now but with how easy they were to mount, switching to latex will be easy.
For those with experience using both: Power TTs or Power Cups? I’m guessing the former offers a bit lower rolling resistance and the latter offers a bit more resiliency?

Ran Power TTs in 2022 at, cough, cough, Kona. Lol. And then at Choo last September, which was good for 3rd in AG.
They feel great, haven’t had issues with them regarding durability… and, well, they were fast enough for me.
