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.
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.
DERAILLEUR: 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
• G-Spec finishing touches:
• Carbon fiber cage & Upper link
• Extra wide parallelogram pivot
• Sealed cartridge bearings pulleys
SHIFTER: 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.
• Shift levers designed and located for optimum performance by Aaron Gwin

“RIPPIN TRAILS LIKE THERE NO TOMORROW.”
The TR12 and DH7 drivetrain systems are the result of an intimate development relationship with
5x DH World Cup Overall Champion Aaron Gwin and his personal mechanic John Hall. From start to finish, this project has spanned more than two full years of conceptualizing this high-performance design.
“There are a wide range of bikes, riding styles and riders today. TRP has focused on specific segments to launch its new product. After the first two years working successfully with Aaron and John on brakes, we showed them our ideas for a new TRP shifter and derailleur. When we asked them if they wanted to become part of the development team, they immediately were open to shift their focus to drivetrain. Since then, they have been pushing and challenging us – which is why we like working with Aaron and John.” -Lance Larrabee, TRP Managing Director
“IT PREVENTS YOUR DERAILLEUR FROM LIFTING, SLAPPING AND MAKING A TON OF NOISE”
TRP engineers worked closely with John Hall to create the Hall Lock. A Lever integrated into the B-knuckle mount, which can be opened or closed, as needed. For working on the derailleur or changing the wheel, the Hall Lock is opened. When locked, the derailleur is stabilized for the roughest conditions. This feature helps maintain the utmost accuracy in shifting and superb chain retention. Its clamping force can be adjusted to balance stability and security with the derailleur’s ability to deflect on impact.
• Hall Lock is an on/off feature with adjustable force that brings TRP’s derailleurs the utmost stability, accuracy, chain retention and quietness in operation for mountain biking’s roughest conditions
• It can lock-out the main pivot bolt to prevent your derailleur from lifting, slapping and making noise
• You can set it up however you like – if you want maximum stability you can lock it; if you like it to move like a standard derailleur you can adjust it to do so
The second derailleur feature is a ratchet style clutch, which is adjustable. Depending on a full suspension bike’s design, there can be enough chain growth to feel resistance from the clutch. If a rider wants to free up the system up, he or she can back off the clutch to balance pedal feedback with the clutch’s chain retaining properties.
• Large diameter clutch surfaces for wear resistance and predictable force generation
• Oversized friction surface area for consistent force output
• Adjustable clutch force provides a wide range of customizable ride tuning and compensation for wear
• Quick and easy on/off switch removes all clutch force when needed for wheel changes
• Robust pawl engagement
• Indicators printed on the knuckle and the cage for easy viewing
• This marking helps ensure a quick and accurate measure of the system’s required chain length
Shop mechanics and home wrenches both will appreciate when components can be set up quickly and smart. Saving time for set-up and providing an easy check for assurance.
• Marking aids help mechanics and riders in setting up the B-Adjustment gap and ensures that an accurate adjustment can be made quickly and without special tools
