I use these tires on Zipp 303S Rims for all road riding and very light gravel. I mount them without using a lever but it takes patience. I also have to use an air accumulator tank to get them to seat. The first set of tires only lasted 1,000 miles even though the tread indicators were still visible. I swapped them out because of cuts on the front tire and tread damage to the back tire even though they never went flat during a ride. Road and bike path conditions where I ride are horrible and encounters with broken glass, tree debris and cracked and bumpy pavement are frequent.
I used this tire on Enve 7.8 wheels setup tubeless with Stanz sealant. Raced at IM Arizona with a 25 mile practice ride (PR 449 bike split) same set of tires at St. George 70.3 25 m practice (PR 226 bike split), Washington oly. cut the sidewall on the rear tire first ever DNF. Used the front tire for a 100 mile Time Trial in the mountains of Idaho (PR 445) Replaced both tires (front tire 400 plus miles, 120ish on the rear) brand new tires for Ironman Ireland cut the rear tire 50 miles in. Sealant would hold and then leak off, re-inflated the tire 5 times to finish, riding the tire underinflatednear flat for most of the second half of the course. I would recommend this tire for shorter, clean courses and only for racing. I will not be using this tire for ironman going forward. This tire is thin, flexible, light, and fast, however prone to damage in rougher conditions.
