Freewheel width: 17.7mm

This freewheel must be bedded in before trials use, to ensure any excess grease used when assembling the freewheel works away from the mechanism. You can do this by riding the freewheel around 'normally' for a few hours, both freewheeling and engaging the mechanism gently. 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. Failure to bed the freewheel in correctly will void the warranty.
