Tech Talk: Rohloff's "Through-Axle" A12 Hubs
In 2016, Rohloff introduced a new version of their renowned SPEEDHUB 500/14 14-speed internal gear hub that works with through axle frames. Dubbed the SPEEDHUB A12, Rohloff offers versions to fit frames with 12x142, 12x148, 12x177, and 12x197mm spacing. The SPEEDHUB A12 is nearly identical to the standard Rohloff SPEEDHUB 500/14, with the exception of how the hub connects to the frame.
