I am currently designing a custom direct mount rear mech hanger for my bike (as one doesn't currently exist). I've successfully designed and built a standard mount using PVD's Framebuilder Wiki. However I've not had any success finding the same information to allow me to design a direct mount version. Can anyone point me in the right direction?

  • Same question here.. I know I can measure but why isn't the standard (or something approaching it) anywhere online? Jan 9 at 2:14

If you've got a design for a regular hanger, then you can measure a B-link and integrate it into your existing design. 3D printing helps greatly for testing the fit. I know that's not much to go with, but that's basically how I designed my DM hanger (had to reverse-engineer the stock one first too). Email me at [email protected] and I'll send you all the CAD files, maybe this will help.

If you didn't already, you might want to check Velofrezer, they have a good hanger library and I even donated my design to them. Not sure if they ship out of Russia at the moment, with the war going on and whatnot.
