Record 12x Rear Mech Dramatically different & elegant design for the rear derailleur produced in an ultra-light technopolymer with reinforced long strand UD carbon fibre. 3D Embrace technology is huge step forward from current derailleurs function. When you see how the derailleur shifts, youll notice that the jockey wheels are incredibly close to every single sprocket giving smooth, instant shifts & maximum efficiency. The derailleur also weighs less but maintains the same rigidity & durability. The trajectory curve has been optimized for 11-29 & 11-32 cassettes. A new upper body return spring has been redesigned to absorb road vibration & protects the derailleur from violent movement on the road. It can also fit direct mount & and standard systems making it easier to remove the wheel during the maintenence..
