Reviews over the

Rotor Direct Mount Oval Sram

No installation problems, except for a not very precise offset (I had to add a washer to the chain guide on my Scott so it wouldn't rub). More seriously, a lot of noise when pedalling with a new 12v X01 chain (well lubricated with 'rock n Roll' before fitting), with a sensation of resistance when pedalling. There's a problem with the machining or design of the longitudinal profile of the teeth. I'll try another rando, but if it doesn't improve, it'll be taken off the bike.
