TBH my Zipp Tangente Speed RT25 tubeless feel amazing at lower to medium pressures. They're manufactured by Hutchinson also, along with the new Mavic tubeless. My only complaint about Hutchinson manufactured tires in general is their tread longevity.

Has anyone measured the 28mm installed yet?

my 0.02c worth:

Just fitted a set of 28mm Velo's (standards) to the SLR 2018 Emonda. 17C wheels. measures 29mm wide, BUT 27mm tall. So these are not as wide as the GP4000SII 28mm, which come to 31mm, but are a touch taller. Something to think about. I am using R8000 direct mount calipers and there's heaps of room. The GP4K28's rubbed on the calipers before hitting the brake blocks.

I am very, very impressed with the road holding, cornering and smoothness of the tyre. These beat the GP4000SII for cornering stability, feedback and handling due to their shape when installed and braking grip is far superior.

So to anyone considering these in 25 or 28mm for a fast road or racing tyre, don't hesitate. give them a go. Very happy. I'll consider a set of 4S for the training wheelset.

Thanks for the review and comparison to the GP 4000 S II, it's on my wishlist for the year.

I’ve ridden on the Velo 4S 28c’s. Soft and supple with excellent grip. Could only do 1 ride though due to caliper rub as they are a tad too tall for my frame.

Again "opinion" instead of experience.... Did you rode them, had in hand at least ? No ? So stop trolling.

I'm gonna chime in with my experience with the Pirelli Pzeros,sorry if I'm late to the party.

I've been using them for 5 months on my recently sold TCR and I yet have to decide if they were worthy tires. The main issues I've had was getting the right operational pressure, at that point gripping was excellent but supplessness not that so. I've always found them to be the french cousins of Continental GP 4000s,tires I do dislike a lot. Durability is top notch,after 5 months on bad roads and with a big and heavy rider like I am they still looked brand new. All in all I'm not a fan of "round" tires and the Pzeros are very round. I'll most likely test them again on my 40mm Fulcrums and see how they perform,price is worth to give them another shot before going back to my beloved Sworks Turbos.

Data point: My first Pzero outright failure this morning. I probably have 10-12k+ miles of Pzero Velo experience between multiple bikes (of course I have changed them perhaps every 3k miles or so).

Today, I had a wee bit of a power-slide rounding a corner @ 20mph and damaged the tire. I pushed much too hard for the next 5 miles @ about 25mph and finally decided it was time to pull the plug and limp home. Fresh Pzero rubber will go back on the bike tonight, and I'll continue to run this brand/tire for the foreseeable future.

Anyone with p zeros 4s who can measure them on 17 c rims? I had problems with wheel clearance on my bike with contis 4000s2. I need something softer for winter rides. I use vittoria corsa g+ now because they get to 26 mm and provide me enough clearance. On https://www.bicyclerollingresistance.com/ they measured they are 27 mm wide. What I found with contis is that they get wider with use. I measured 29 after 4k. Thank you !

Not what you asked for, but my Pzero velo 25 (not 4s) measure 27.18 (both f+r) on velocity A23 (18mm) rims after about 2500km.

Thanks for reply ! Yes now I have to transform 18mm into 17c rims :D Can't find any reference for rim inner diameter of my fulcrum racing quattro lg :D :evil: I need some winter training tires. Last year I had crash because of vittoria corsa g+ 25. Not handling very well in wet icy weather.
