Component Deals & Selection / Re: ZTTO MTB M1 Boost hubs 28H 54T Ratchet
« on: February 10, 2024, 05:15:35 PM »
I just received a set of M1 and R2 hubs and built them up on btlos carbon rims.
I've discovered though that the tolerances of the new hubs are different to the older ones I have used. They no longer fit DT Swiss ratchets, nor do they fit the older ZTTO ratchets. I contacted ZTTO and they send me a new freehub and it has the same problem. The new ZTTO 54t ratchets have a different spring design with a red cap.
Has anyone else had this experience?
This is a bit annoying as now I need to spare different ratchets for these hubs. Might look at goldix or arc hubs next.
