I run the Pirelli with a 700 x 28 on my front wheel. This is my first time using this tire but I am happy with it. I have it on my road bike, carbon wheels, and run it tubeless. I have about 1500 miles on it so far and I think the grip is really good and no flats or issues. I feel it must have good flat protection because I ride over the occasional crud on the road and no flats. I pump it up to about 85 and add air about once every 3 rides but it doesn't need much air, it holds it's air pretty good - better than my bontrager R3's. I would buy this tire again.
I have 5-600 miles on the tires with no issues. They roll fast and I have been using them on my Ti gravel bike riding on group rides. No problems staying with the faster groups and they handle the rough roads out here great. Been running about 60 psi in the tires and they still roll fast.
They were relatively easy to install on my set of Zipp 303 Firecrest wheels. (My previous experience with road tubeless were with Schwalbe Pro Ones and Conti 5000 which were significantly more difficult to install.) The tires are expensive but so far I am impressed.
I changed to these hoping they would be easier to mount tubeless on my Campy Boro WTO 45s. They went on very easy. Popped in place and sealed up nice with just a floor pump. Only been out 1 time for about 40 miles, but they felt nice and smooth at 80 PSI. My weight is 195lbs.
In light of the lack of continental availability had to try a different option. This Pirelli is doing the trick. Holding air well and mated well as a tubeless option on Reynolds carbon wheels. No flats to date! (hopefully I didnï¿½t jinx myself)
I ordered these earlier this year, when the Continental 5000 TL was on back order. I run 28 x 700 at 60psi, on Enve SES and found the installation easy. I replaced only my back tire, and it was hassle free for more than 2000 miles. I ride on roads that have a lot of pot holes and debris. Although I prefer the Contis to the Pirelli, the Pirelli is now my go to when the Contis arenï¿½t in stock.
