Just saw the newly tested Vittoria Corsa Tubeless G2.0 by bicyclerollingresistance.com (https://www.bicyclerollingresistance.co ... rsa-g2-tlr)

And I was a bit surprised to see that rolling-resistance numbers are not that low versus the clincher version. In fact, if you look at the preceding tests from bicyclerollingresistance.com on Vittoria Latex versus Conti Race 28, you can assume that the clincher version is about 1W per wheel faster at (18mph/29kph), that's 2w for the whole system at a fairly low speed, not so marginal gains...

20 ml sealant is very low amount for cotton wall tires too. A lot of those sealant will simply absorbed by the tire and therefore users are likely fill 30-40ml instead of 20ml.

If you like tubless cotton tires Veloflex might be a better option. See aerocoach and cyclesetforme for data.

23mm and higher presure -> no thank you

?? tubeless Veloflexes come in 25 and 28mm, no?

Veloflexe 25mm are not very impressive in RR vs GP5k.

Anyways, point was not to talk about the best tyres, rather to have a comparison of Latex vs Tubeless on a similar tire

Now let's compare puncture resistance!

It's not just rolling resistance that's pushing tubeless, it's better puncture protection with no losses when it comes to rolling resistance.

Yeah that's weird the TLR is slower than the clincher. It's 37 grams heavier but still. If you stick a latex tube in the TLR then the difference is even bigger.

What's even more amazing is that the TLR is 4 watts slower than GP5K TL.

If you're chasing Crr, there's a handful of TT tires and the GP5K clincher and TL. All else is fungible.

If you want a durable, grippy, self-sealing tire that feels great to ride, go with the Goodyear Eagle F1 TLC.

Again, the point is not really to look for the fastest tire around, I would have mentioned the Corsa speed otherwise...

Just surprised that for a similar tire, when we had similar RR on GP5K (GP5k-TL vs GP5k-clincher with latex Vitoria), we have a difference of almost 2w per wheelset with Vottorias

Just shows tubeless is a silly as dork discs on a road bike. A road bike isn't meant to be a mountain bike, even is Trek and Specialized and others are trying to make it so.
So tubeless is faster/lighter/more puncture resistant? Do you still rent videos at blockbuster and lookup businesses on yellow pages?

You made a typo I believe, or didn't read the first post...

Jokes aside, I runntubeless, they have their advantages, but speed is not necessarily one of them.

Oops I guess I did. Anyhow, tubeless is faster than butyl tubes by more than latex is faster than tubeless. Like you, I'd trade puncture resistance over 1w any day.
