Replacement 142 x 12mm Axle Kit for the MT Supadrive SS hub. This Axle Kit is made from a tubular Cr-Mo steel core with CNC alloy end cones. This allows the MT SS Supadrive rear hub to be run with 142 x 12mm thru-axle system frames. Our optional MT Supadrive Boost Disc Adaptor allows you to further convert the hub (using this axle) to run in a 148 x 12mm thru-axle boost fitment frame.
