Shimano's Deore XT Rear Derailleur is ready for the rigors of off-road riding and racing with a lightweight aluminum body and low-friction pivots for incredibly easy and smooth shifting. And the XT features 11-tooth pulleys, which alternate chain-link contact reducing wear and smoothing pedaling.
Great price, I bought 2 of them. Its something you don't think about, when the deraileur goes out or gets tired replace it with another XT. It shifts great right out of the box (or bag as these guys sell them). Wheelworld sells these OEM XT's and thats why theyre so cheap. It doesnt come with any box, insructions or anything. But its like a toothbrush, something you already know, unless youre a newbie.
Bottom LineYes, I would recommend this to a friend
