Does anyone know what the mount spacing is between the mounting stud for a Shimano Altus M310 short cage rear derailleur and the rear wheel axle? What about the geometry for the mounting and the flat for adjusting derailleur angle? Is there a spec sheet for putting those features into a frame and I’ve missed it or is all this information proprietary? I found this, but it doesn’t give anything useful.
Thanks!
If I interpret the question correctly, it looks like you’re after Shimano’s standard rear derailleur hanger spec, which is largely the same across essentially all derailleurs with a standard mounting configuration.
Thanks! Is this document available from Shimano or only something bike shops have under agreement with Shimano? I can’t find it hunting through the documents on https://si.shimano.com/en/.
Have a look here:
(I just Googled “shimano technical information pdf”)
