Derailleur and shifter kit TR12 - 12v

The TR12 drivetrain consists only of a shifter and a rear derailleur. All the work done around noise reduction is found on this derailleur. This derailleur has many technologies; like the HALL LOCK, CHAIN LENGTH INDICATOR and ergonomics. HALL LOCK technology: This function locks the B-Knuckle (the part that connects the derailleur to the frame) once the derailleur is mounted and adjusted. CHAIN LENGTH INDICATOR technology: A marking that makes it easy to determine the optimal chain length.The new TRP TR12 derailleur brings new functionality to racing.TRP was able to work with Aaron Gwin and his mechanic John Hall to improve this derailleur and its shifter.The shifter was designed by Aaron Gwin to give you more precise thumb contact and better grip. The shifting will be much more efficient.
