The Mavic Speed Release axle stays on the wheel when removed from the bike and the indexed system allows a faster wheel change

The controlled torque enables the design of the right axle strength at only 40 grams in 12x100 (front), 45 grams in 12x142 (rear) and 47 grams in 12x148 (rear Boost)

The integrated torque control system ensures consistent tightening force during each use and the indexed system keeps the axle/wheel in the fork/frame when unscrewed.
Only compatible with Speed Release frame and fork
