Extention Rise Chain Tensioner

Extention Rise Chain Tensioner

New double sheave chain tensioner for Extention Rise trials bike, fitted as standard on the Extention Rise 20" trials bike range.

- It has two 8-tooth sheaves, CNC machined from 7075 T6 aluminium, to withstand the wear and stresses associated with the chain.
- Sealed bearings ensure the sheave turns freely and smoothly in all conditions.
- The tensioner arm is 10 mm, which allows it to adapt to Extention Rise 20” trials bikes.
- The tensioner body is made of high quality aluminium alloy.
- The chain tension is adjusted by means of a 6 mm Allen key, by means of which the relative position of the two sheaves is adjusted by turning the spring clip.
- Thanks to its compact design, this tensioner is protected inside the right chainstay of the frame, so that it is hardly exposed to impacts.
- Supplied individually.
