Need to convert your 100mm spacing Mavic mountain wheels with a 15mm thru-axle to a quick release set-up. This is the kit you need. You get two machined Mavic 15mm to QR adapters and a Mavic BR101 QR lever for a full conversion.

The change process is simple, and tool free. You may need an axle vise to remove the existing end caps, but often you remove them by hand. We recommend you clean them to be free of grease, dirt, etc., then grasp the cap and pull off. Do not use a bare tool or plier, as you may mar and damage the aluminum.
