Clean 135.9 Cassette Freewheel

Description and materials
- New 135.9 edition of Spanish brand Clean’s cassette freewheel.
- This is an improved version, with more engagement points and a more reliable inner mechanism.
- Since this is a cassette-type freewheel, it isn’t threaded onto the crack, but it sits on the crank or BB axle splines.
- The splines on the freewheel are Shimano Splined HG standard, which is compatible with Clean BB30, Bonz BB24, Crewkerz AS30 and those cranksets that use that same interface.
- Both the main body and outer ring are made of high-strength machined steel.
- Features 9 high-strength treated steel pawls, with 3 offset groups of 3 pawls into a 45 teeth ratchet, providing a total of 135 engagement points per revolution.
- Reinforced springs are able to deal with higher tension to ensure maximum wear resistance and amplified sound.
- Includes a 1mm thick spacer, which can be useful to obtain the desired alignment.

Compatibility
- This freewheel only fits cranksets with Shimano-type splines on the freewheel base, like Clean’s BB30, Crewkerz’s AS30, the new Bonz BB24 cranks, and those with the same interface.
- Not compatible with Hashtagg and Try-All BB30 cranks, nor Echo cassette cranks.
- Compatible with both 1/8” and 3/32” chains.

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.
