TR12 DERAILLEUR
One key drivetrain feature that separates the new TR12 derailleur from the cycling industries existing products is the Hall Lock, named after Aaron Gwin’s mechanic, John Hall. The Hall Lock is a lever integrated into the derailleur mount, which locks the movement of the B-knuckle around the mounting bolt when closed. The Hall Lock can be opened to easily remove the rear wheel. When closed, it provides additional stability and less noise to the shifting perfomance.
The new TR12 rear derailleur is able to provide a quiet and accurate ride over the roughest trails. The key feature to this pursuit is the Hall Lock. During the Race season, lead mechanic for Intense Factory Racing, John Hall, noticed excessive movement around the b-knuckle when riding over rough rock gardens and in tracked out corners. This was leading to more chain skipping and slapping creating possible variances in shifting. This inspired John’s idea to lock the B-knuckle to the bike’s derailleur hanger. TRP engineers worked closely with Hall to create this feature, The Hall Lock.

- Hall Lock
- G-Spec Ratchet Clutch

TR12 SHIFTER
Sequential Shifting – like a ralley car. Speed of shifting is key, which is why we developed something a little different. As a result, TRP engineers looked at the cable release lever and devised a system to move it in a linear path to mimic the motion of a rider’s thumb, rather than rotating it away. This unique positioning allows for a more consistent contact patch providing overall better grip and shifting performance when the trail gets rowdy.
Ergonomics are key to Aaron, which is why he wanted something a little different. As a result, TRP engineers looked at the cable release lever’s ergonomics and devised a system to move it in a linear path to mimic the motion of a rider’s thumb, rather than rotating it away. This unique positioning allows for a more consistent contact patch providing overall better grip and shifting performance when the trail gets rowdy.
Features:
- Shift levers designed and located for optimum performance by Aaron Gwin
- New linear actuation for improved ergonomics and consistent thumb contact
- Enhanced grip & tactile feel built into lever paddles: embossed grooves on advance and release lever
- Carbon fiber upper housing & advance lever position with brake lever
- Ball bearing equipped
- 12 speed groupset
- Tool-free straight lace cable changes
- Rider adjustable home position of lower lever with a 40-degree range
