Description
13T rear derailleur jockey wheel for Shimano 12 speed RD (XTR, XT). Printed using PETG, so far so good. You will just need to use the old jockey's bearing or a replacement bearing and bearing side covers
Teeth are intetionally slightly over-sized to make chain seat on initial use to ensure proper fit.
