Sprung chain tensioner, fits to rear mech hanger.

For use with Speedhubs on non-adjustable vertical dropouts, or with rear suspension.

Note: Chainline is set for Speedhub use, and therefore not ideal for non-speedhub chainline uses.

Note: DH version is very short, and for Extreme DH use.

Note: If you intend to use a chain tensioner with the new splined sprockets, then a longer mounting bolt (HURO8255) and more distancing washers (HURO8256) may be necessary to make this fit with the wider 58mm chainline that the splined sprockets use.
