This rear thru axle is specific for using your Mavic Speed Release bike on a wheel-on trainer. The thread, a "double lead-in thread", is proprietary to the Mavic Speed Release system only.
Purpose built to adapt your thru axle equipped bike with your wheel-on trainer, such as a 1up, Blackburn, Cyclops, Kinetic, Tacx, Wahoo and many other trainers. Our goal is to fit the thru axle to your bike perfectly, so we minimize spacers and extra parts, providing a clean, high performance axle for your bike. Train, warm up and be race ready and fit for the season.
