Description and materials
- New high quality freewheel designed by French Biketrial brand Bonz.
- Now, it features 135 engagement points, so it’s a considerable improvement in respect to current freewheel with 72, 108 or 120 engagement points.
- This is achieved by using 9 high-strength, heat treated steel pawls, offset into 3 groups of 45 engagement points each, providing 135 engagement points per revolution.
- The traditional 4-removal pockets have been replaced by a multi-pocket pattern, as in most bottom brackets, so it can be removed with a common ISIS BB tool.
- Standard 1.37”x24tpi thread, so it’s suitable for most threaded hubs and cranks.
- Oversized springs increase reliability and durability.
- Rubber seals on each side of the freewheel keep all the mud and dirt out of the inner mechanism.
- Available in 18t only.
- Anodized black finish, with white laser etched Bonz 135 9.3.45 graphics .

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.
