Additional information



We recommend to follow freewheel Break-in procedure , Ride gently for a few hours before it is subjected to trials use. This way we ensure:

- any excess grease used when assempling the freewheel works away from the mechanism

- pawls will engage correctly


If the freewheel is subjected to trials use without having been bedded in, the pawls will not engage correctly and this causes the freewheel to skip, damaging the pawls and ratchet.


Freewheel must be broke in before heavy use.  To do so, just ride the bike around town for a couple hours to seat everything in.
