Parts & Maintenance Shimano Derailler-RR 11S 105-5800 Black

The Shimano 105 5800 Rear Derailleur offers excellent shifting under all conditions. Increase rigidity and reliable long term quality with this 11 speed wide link medium cage rear derailleur. A few grams heavier than the higher-end and lighter weight Dura ace and Ultegra models, but many of the same features make this an excellent bang-for-buck choice for the budget racer.

This is a short-cage derailleur; chain wrap capacity allows for use with double drive trains (not for triple ring crank-sets).
