Speed trap ahead.

Designed to provide the perfect blend of traction, comfort, and race-winning speed, these 25mm and 28mm wide tires take what Zipp learned in their Tangente Speed R28, and added in a tubeless casing that allows you to benefit from more grip and less rolling resistance. Double down on traction and cut out excess rolling resistance, and make those long races more comfortable. When paired with today's modern wider rims like the new Zipp 303 Firecrest, these tires provide a smoother rim/tire interface for improved aerodynamics.


Features:

  • Tires measure 700 x 25mm and 700 x 28mm wide respectively..
  • 127 TPI Nylon Casing.
  • Tubeless-ready.
  • 292 grams (RT25) and 302 grams (RT28).
  • Water-siping tread pattern improves wet weather handling.
  • Supple over rough roads, eating up cobbles and gravel just the same.

Fast with good traction but very poor durability
rating

Bought a total of 6 of these tires to mount on my new Zipp 303 Firecrest wheels. Very low rolling resistance with reliable gripping on corners. However, all of these tires consistently wore out after 800-1,000 miles of use on paved roads. Once you hit that mileage, just expect to get a flat tire. I am still searching for a reliable alternative tire that can be mounted on hookless rims. Hopefully Continental will develop a new tire soon (Continental GP5000 cannot be mounted on hookless rims).

I purchased the 700x25 size and mounted them very easily on my Campagnolo 2 Way Fit wheels with only my hands and a floor pump. So far, so good. However, once mounted they had the profile of a narrower 23c tire. I was surprised, but it didn't seem to affect ride quality that much, and I was still able to run 85ish psi in the rear and 80 front. Traction was very good, wet or dry. Had zero punctures.

This is where the review goes downhill.

With only 1100 miles on the pair, the rear tire tread surface is worn through to the cords. I was very surprised, as even the crappy 1st-gen Hutchinson Fusion 3s gave me more miles before wearing through. I got a good deal on these tires, but was hoping they would last for a couple thousand miles anyway.

So, I will rate these Zipp tubeless tires as disappointing.

These tubeless tires are the real deal. Installed easily. Very smooth and grippy. Have only ridden them on wet roads once but they performed great. On my 2nd set and will definitely continue. A little pricey but worth it.

I have questions about why tubeless tires need to be heavier then my former clincher and tube combinations. When you add 2 oz of sealant it gets even worse. However, I have have been running this tire on the front for a few weeks, without sealant. It is holding air pressure better then my Kenda with sealant on the back. Two rides ago I ran over large pieces of broken glass that shattered more under my tires. The rear Kenda did fine, possibly because of the sealant. The odd thing was that the front Zipp without sealant, came out perfectly and that was the tire that hit the most glass. That one still holds air better then the Kenda.

Its before ride review, little advice for installation process. It goes on a rim pretty easy, 19mm inside 27mm outside VENN REV 35 TCC tubeless ready. Tires are pretty much impossible to set without compressor dont even bother with floor pump or CO2, need quick air supply. Let them spent day on whell first, use no sealant at first, add it after initial tire set up, this will save you lots of spills. Have fun and ride on.

Maybe only for Zipp tubeless rims

Tried these on my new TCR Advanced carbon tubeless rims, they just dont pair. These may mesh with Zipp tubeless but they dont fit the Giant rims. Went back to the Gavia tires and fit perfectly. Also no issues running Continental GP (with tubes) the Giant rims.

Ive tried a lot of different tubeless tires with varying results. So far, after just a few hundred miles on these, the Zipps (25) seem a great combo of handling, forgiving ride, low rolling resistance and durability. One glass puncture on the rear so far but no tire would have prevented it and overall wear and puncture resistance seem good.
