BLACKBEARING Rear Thru-Axle 12x135 mm (12mm-159-M12x1-15mm)

The BLACK BEARING AX-R12.9 rear thru-axle is made of black anodised aluminium and is CNC machined, providing a reliable alternative to the original axles fitted on most road, mountain, and gravel bikes. It features a 12 mm diameter with a total length of 159 mm, ensuring precise wheel retention in the frame.

The 1 mm pitch thread locks with an Allen key or dedicated tool, ensuring secure and durable wheel clamping. A conical head interface also optimises wheel centering during installation. Lightweight and corrosion-resistant, it simplifies routine bike maintenance thanks to its tooled tightening, for regular use on both road and off-road.
