TRP TR12 Rear Derailleur and Shifter Kit

Get World Cup downhill shifting technology on the trail with the TRP TR12 Rear Derailleur and Shifter kit. The 12-speed derailleur and shifter provide smooth, accurate shifting through rough terrain.

• Derailleur has a Hall Lock—a lever integrated into the B-knuckle mount that locks out the main pivot bolt to prevent the derailleur from lifting, slapping and making noise
• Hall Lock can be turned on or off, and the clamping force can be adjusted to balance stability and security with the derailleur's ability to deflect on impact
• G-Spec ratchet-style clutch keeps tension on the chain through the movement of a bike's travel
• The clutch has integrated adjustability, effectively providing the individual balance between pedal feedback and chain retention for your bike's chain growth
• Derailleur features a carbon fiber cage and upper link, extra-wide parallelogram pivot, and sealed cartridge bearing pulleys
• Shifter features linear actuation for improved ergonomics and consistent thumb contact
• This unique positioning allows for a more consistent contact patch, providing overall better grip and shifting performance when the trail gets rowdy
• Enhanced grip and tactile feel built into lever paddles with embossed grooves on advance and release lever
• Carbon fiber upper housing and advance lever position with brake lever
• Shifter is equipped with ball bearings
• Rider-adjustable home position of lower lever with a 40° range
