Ran these on the 2025 Unbound 100 with absolutely no problems. Would buy again when these wear out.
YUP, these tire are indeed all that. Running the 48mm Thundero HD on Zipp 303S. Though come to think of it, don't use these tires if you're racing against me in men 60+...
Great tires! Was using Pathfinder pro 42's before and never were in love with them, never felt like I had good traction in a turn. Got the Thundero HD 44's for Unbound and they were great! I felt much more stable in turns and felt they were still a fast rolling tire. Performed great at Unbound, I did have one tiny puncture but it sealed itself very quickly and didn't need to add air.
Great on gravel, great on tarmac.
Not for weight wienies, if that's yr bag.
I bought these to replace a pair of worn out Gravel King SKs. These tires are more supple, roll faster, and are more fun to ride! Highly recommend.
I do a mix of paved trails, forest roads, single track and gravel. These tires perform great on all surfaces, good grip and smooth rolling.
Great rolling resistance without compromising grip and durability.
After trying many other tires in the market, I think that this will be my go to for a while.
