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 assembling 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.
