Our thru axle conversion kit can replace the original thru axle on most mountain bikes, to allow for trainer usage. This kit will also allow the installation of a Copilot trainer hitch for most thru axle bikes as well. Works on bikes with 1.0 OR 1.75 thread pitches, and hub widths from 135-148mm.

142 or 148mm). Next, choose the correct thread pitch by
either comparing your thread spacing to the thread scale
