Description and materials
- New version of the popular Echo TR 108.9 freewheel, now available in a splined version.
- As a novelty in this version, this is a splined freewheel, which means it’s not threaded onto the crank/hub, but pressed onto the crank/hub’s splines.
- This freewheel is regarded as the most reliable by most riders, and that’s why it usually lasts for a very short time in stock!
- The composition of the Cr-Moly steel of the outer teeth and base has been revised, in order to increase their strength to be able to cope with chain stress much more efficiently.
- Its unique spring design ensures it almost never skips, while also being much louder than most freewheels.
- 9 heat treated steel pawls are offset into groups of 3, with 36 teeth, resulting in 108 engagement points per revolution.
- Features Echo’s own splines, only suitable for Echo Splined cranks and hubs.
- Echo’s own 4 large removal pockets are also compatible with the standard 4-pocket freewheel remover.
- Available in 18 teeth (18T), in black with grey Echo graphics.

- This freewheel can be installed on cranks and hubs with Echo-type splines.
- Not compatible with BB30 or BB24 cranks.
- Can be used with 1/8” and 3/32” wide chains.

- Available with 18 teeth (18T)
- 9 pawls and 108 engagement points (108.9)
- Tooth thickness: 2.2mm
- Thickness: 17mm

- Black, with grey laser etched Echo graphics

- 181.10g

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.
