12 mm Speed Release Rear Trainer Thru Axle

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. The goal is to fit the thru axle to your bike perfectly, so to 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.

• 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.
• Weight: 0.3125 lbs
• This axle is compatible with BKool, Blackburn, Cyclops, Kinetic, Tacx, Wahoo and many other on-wheel resistance trainers.
• The true length of the axle shaft is 165 mm. Please note: Thru-axle lengths do not equal hub standards. An axle has to be longer than the hub to fit in the frame. A 12×142 hub does not equal a 142 mm long axle.
• This axle has a proprietary “double lead-in” thread found only on Mavic Speed Release bikes.
• The axle shaft and axle ends are precision CNC machined from 7075 aluminum, and hard anodized for rugged durability.
