Secure rear wheel fixing for disc-brake bikes

Shimano's E-THRU axles hold the wheel securely and come out again without a fight. The SM-AX720 uses an internal cam mechanism for consistent clamping force, and the lever position can be adjusted so it sits where you want it when the axle is tight.

  • Rear E-THRU axle, 142 mm width, 12 mm diameter
  • Internal cam mechanism for stable fixing force

Clean and simple

The cam lever keeps the axle tidy against the frame and makes wheel removal a tool-free job, which matters when you are packing a bike or fixing a flat away from the workshop.

Compatibility and fit

Rear axle for frames with 142 x 12 mm thru-axle dropouts. Thread pitch and required axle length vary between frames, so check your frame manufacturer's specification before ordering. Tune Cycles can confirm the right axle for your bike.
