105 RD-5701-L 10sp Rear Derailleur

The 10 speed SIS 105 rear derailleur integrates the wide link design prominently featured in both Dura-Ace and Ultegra derailleurs to not only promote quick shifting, but to preserve the pivots for greater durability and long term crisp shifting performance. Shimano's 105 group is perfect for riders who are looking for performance components, but don't have a race-level budget.
