One 12mm to 16mm inclusive collet with M6 thread for Oberon Mirrors. Will grip the internal hole of handlebars that fall within this range. For handlebar bores smaller than 14 mm the collet will need to be pushed into the handlebar without the Oberon Performance bar end, then re-assemble onto the bar end prior to adjustment and tightening. The brass collet and stainless steel expander bolt can be tightened with quite excessive force, usually you will hear an audible groaning sound as the brass collet tightens to the required torque. For handlebars with an internal bore of between 16.5 and 20mm you will also need to choose one of the aluminium adaptors.
Fits the following model(s):
