Product Description
Shimano Dura Ace RD-7900 Rear Derailleur: Sports & Outdoors. The RD-7900 has an expanded chain-wrap capacity so you can use it with any combination of Dura-Ace cranks and cassettes (including a combo of 50/34 and 11/28). Some rear derailleurs snort, snicker, and flat-out refuse to comply when you think about choosing a 50/34 crankset and a 12/27 cassette. Not the Shimano America Dura-Ace RD-7900 Rear Derailleur. What else is rad about this piece? Shimano America made the pulley cage and P-body with carbon fiber so this derailleur weighs in at a modest 166g.
Shipping Weight: 12 ounces
