Description
The Dura-Ace 7900 front derailleur by Shimano has pushed the limits of optimal shifting once again. This season's version of the popular Dura-Ace line's front derailleur has been engineered so that no trim is necessary on the outer front chain ring, making up shifts simple, quick and allowing the rider to concentrate on the road ahead. It has also enhanced spring tension for the smoothest shifts possible from any drive train. A must if you demand the best front shifting system possible.
