Additional Information
It is highly recommended to bed in the freewheel for a few hours before trials use to make sure any excess grease works away from the freewheel and the pawls work correctly.
If you want to speed up the process, just apply some oil between the outer teeth and the centre of the freewheel.
If you don’t bed in the freewheel before trials use, it won’t work correctly and will skip, therefore damaging the pawls and ratchet.
Damage occurred to the freewheel because of inappropriate use will void the guarantee.
