Axle to fit standard (ie not singlespeed) DT Swiss 240 hubs.
Interchangeable end caps allow DT 240 hubs to be used with quick release, 10x135mm bolt through, 12x135mm bolt through and 12x142mm (X12) systems.
Some older DT axles are visually similar to this axle, but the inner diameter is slightly too small to allow 12mm axles to pass through. Fitting this axle and the appropriate end caps will solve this problem.
