Sora R3000 brifters with the M4000 rear derailleur

Bicycles Asked by HC Tang on June 27, 2021

Is the pull ratio still the same ? I can only find info on the older gen sora shifters not the most updated ones..

One Answer

Yes, the rear derailleur cable pull ratio, unlike the front one, is still the same. You can use any (7-)8-9 speed RD.
