Thru-Axle Hub Dummy

Hub-Dummy for (road) bikes with 12x142mm thru-axles. I had some 6003 bearings left over from another project, so I put them to use on this hub dummy, but you could just use a printed one as well.

Use the shims to align the position of the dummy-sprocket (11 teeth) with your rear derailleur. For the 142mm hub width, nominally five shims are intended, but you can vary the amount to compensate for minor dimensional inaccuracies.

I've attached the .stp-file for you to modify, in case you need a different width.

Disclaimer: While I provide all data and information to the best of my knowledge, I take no responsibility for any damage - whether to your accessories, bike or body! If you choose to install printed parts to your bike, that's entirely on you!


~~**EDIT:** Somehow, part #2 (with the external thread) is left-handed for reasons only Creo could ever explain :( Mirror this part in Cura to get a right-handed thread that fits part #1! I'll try to fix this "feature" sometime.
