TRP TR12 RD-M850 Rear Derailleur

TRP's TR12 rear derailleur has its origins in the collaboration with Aaron Gwin and his mechanic John Hall and is a trail and enduro bike made with gears. In true racing spirit, the lower parallelogram and cage are made of carbon and the functionality is limited to 12 speeds with a maximum number of teeth of 50.

The reverse gear has features such as Hall effect locking and ratchet clutch that optimize the transmission with a single drive configuration and minimize chain movement and provide effective noise reduction. A clever symbol on the sprocket makes it easy to fit the right length of chain.
