Shifting just got a whole lot easier with the Shimano 105 RD-5701 GS rear derailleur. Shimano's 105 rear derailleur has benefitted from a steady flow of trickle down technology from their superlative Dura-Ace and Ultegra groups. The wide link design enables you to shift quickly between the gears, and also enhances pivot durability, so you'll get many years of use. The shifting is crisp, accurate and precise. It's ideal for riders looking for top-level performance without emptying their wallets to save a few extra grams. It is cross-compatible with all 10-speed Ultegra and Dura-Ace components.
