**Warning: Not compatible with pre 2015 groupsets.**The Chorus front derailleur excels in shifting performance and is comparable to its siblings Record and Super Record. This mech operation is fast, responsive, and precise with the chain moving between the rings with no hesitations.With the new Super Record, Record, and Chorus groupsets, shifting is extremely easy thanks to the long front plate of the front mech body, meaning greater leverage and therefore truly reduced movement when shifting. Shifting precision is achieved thanks to the design of the new narrower cages. The semi-inner cage, in aluminium, has features that improve shifting speed.NEW CAGE IN LIGHT MOLDED ALLOY: Enabling crisp, rapid, precise and above all silent shifting thanks to the plate on the tip of the outer semi-cage.S2 System (Secure Shifting System): The special support system built into the derailleur safeguards working of the drivetrain, strengthening the points of contact and guaranteeing maximum compatibility with all frames.**Technical Specifications:*** Special inner cage design* CSD (Chain Security Device), optional add-on* Derailleur cable deviator insert* Derailleur clip clamp, optional add-on* Weight: 76g
