Shimano's Alivio Rear Derailleur is built to withstand the rigors of off-road riding, with a lightweight aluminum body and low-friction pivots for incredibly easy and smooth shifting. And, the Alivio features 11-tooth pulleys, which alternate chain-link contact reducing wear and smoothing pedaling.
