Hi, don’t mean to hijack this thread but wanted to share my experience of the One tubeless, 25. Been running this tyre for a month now and completed about 500km on it. It’s fast rolling and certainly more durable than the Ultremo tubeless 23s I had previously. Prior to that, I ran the Bonty R3 25s which was more durable than the Ultremos but feels less so compared to the Ones, so far, IMO.
FWIW, I will always run with 25s for comfort and added confidence when cornering. Weight is 87kg and its 90-95 psi for the rear and 85-90 psi for the front, depending on conditions. No problem encountered descending at 80kmh from Tourmalet, Aubisque or MV2 at that pressure.
XX Cycles just notified me of stock of the 25s. I’ve managed to stock up on 4 spare sets ordered from Starbike given how difficult it was to locate stock anywhere else…
Puncture experience so far in 20 months of tubeless riding – 2 fizzy slow blow outs. Pumped it up ONLY during the ride and completed the rides. Added more sealant when I got home and it was fine. Both times were with the Ultremos only.
Happy riding.
