Shimano Deore XT front derailer - 17160
Given the simple task a front derailer has to perform---pushing the chain from ring to ring, something you can do with a skilled foot or a stick in your hand-- it would seem that ANY front derailer would do just fine. Not so. When the bike is designed right and has gearing that makes sense, a shocking number of otherwise seemingly fine front derailers fail the test. This model is our current favorite, the winner. The clamp is chunky; forgive it and move on. It's the best-shifting triple-compatible front derailer in production, and we are thrilled to offer it. It shifts as well as a Campy model that is twice the price and you will love it (this xt).
