I purchased a set of the super fast (but insanely thin) 23mm Records back in 2020 - super fast but so terrifyingly thin I didn’t feel like they’re something I could run for more than a short TT. Additionally, 25mm is the ideal tire size for my race wheels.
I see now from Veloflex.it that they now have the tire available in both 23mm and 25mm versions, as well as clincher and tubeless ready versions.
Has anyone tried these new new versions? Wondering if they’re any more durable in the clincher, or if the TLR version makes it more durable?

BRR shows the 25mm TLR tread .2mm thicker than the regular 23mm, with better puncture resistance and yet lower rolling resistance. The TLR version is only available in 25mm, which IMO makes sense - I have had little success running tubeless 23mm tires.
It is probably too new for much real world experience, but personally, I’m not convinced that that the lower rolling resistance of 25mm outweighs the lower air resistance of 23mm for mere mortals like me (front tire), riding TT’s outside were there is usually some wind (assuming they are both matched to the correct width rim).
Granted I’m talking about asphalt velodromes, but I wore 3 original Records down to the casing without a failure. So while indeed thin, I feel they have a good amount of “durability” when not talking about puncture resistance. I have zero anxiety riding them.
Also I don’t mean longevity. A few hundred miles to get to the casing on a rear tire.
Using BRR, AeroCoach, and personal user experience, can we come to a consensus as to what currently is the absolute fastest tire combination that you can actually purchase?
The most recent TT I got my ass kicked, the guy who beat me was on a front 23mm Vittoria Corsa Speed G+ 2.0 TLR w/latex tube and a rear 25mm Vittoria Corsa Speed G+ 2.0 TLR, also with a latex tube. This was on relatively smooth asphalt.

Dan Brigham used to run a Michelin TT front and Corsa Speed rear with a staggered 23/25 size. That was the best compromise of aero and Crr and probably longevity on crappy UK roads I would guess it could be GP5000 on the front now, depending on rim width. I don’t know anything about the width of the TriSpoke he was using and it might not work with the 25 width of the GP5000.

Thank you!
I think another factor in the 23mm vs 25mm front tire debate is probably the shape of your frame. The frame’s downtube sits right behind the front tire. My bike is a Scott Plasma 3 with a real airfoil downtube, 27mm thick and a true “horizontal” chord of 115mm - a very smart design. A wider, truncated, kammtail downtube might work better with a 25mm front tire.
Yup, get some of those new hookless rims - you’ll be very comfortable with a 25mm @ MAX 73psi tire, but give me some room to come around around you with my 23mm @ 100psi *uncomfortable *tire - just ignore the smile on my face!

It really does depend on your wheel, but the absolute fastest will be some combination of 23mm/25mm Veloflex Record w/latex tube depending on what wheel you’re using. Personally I run a range of tyres/wheel combos depending on the road surface/conditions: Corsa Speed for most things, Michelins if it’s terribly wet, Conti 5000 TT if the surface is awful, VF Record for superfast courses, etc.
I do think that running the Veloflex TLR 25mm with a tube in is a decent option if you’re worried about how thin the standard Record is. The extra layer inside the casing for tubeless sealing is going to help general puncture protection even with a latex tube. Only comes in 25mm though (so putting a 25mm Record TLR on one of our Titan wheels will be slower than a 23mm for example).
