Campagnolo Der RD20 S Record 12s 34t (SKU 250450)

Built for wide-range gearing, the Campagnolo Super Record 12-speed long cage rear derailleur handles cassettes up to 11-34t. A 12-tooth jockey wheel keeps chain tension constant across the range, and an optimized spring return absorbs vibration on rough roads so the chain stays seated on the sprockets. The removable pivot works with both hanger mount and direct mount frames, and it's compatible with the spacing and axle types common on hydraulic road disc bikes. Finished in black.
