  • TRP’s new DH7 rear derailleur brings a new feature to racing. TRP R&D worked closely with Aaron Gwin and his mechanic John Hall to build an advanced DH derailleur. The derailleur is true G-Spec, utilizing carbon fiber for the outer parallelogram link and pulley cage; offering an adjustable Ratchet Clutch; and adding features born from competition—the Hall Lock, a B-Knuckle lock that reduces noise and increases shifting stability.
    The ongoing competition amongst the best mechanics in the world during a World Cup season is to build the quietest bike on the track. John Hall identified the movement of the derailleur around the B-knuckle as one of the points for improvement. This inspired John‘s idea to lock the B-knuckle to the bike‘s derailleur hanger.

    • Hall Lock
    • G-Spec Ratchet Clutch
    • G-Spec finishing touches:
    • Carbon fiber cage & Upper link
    • Extra wide parallelogram pivot
    • Sealed cartridge bearings pulleys

    Hall Lock
    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

    Ratchet Clutch
    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

    Chain lenght indicator
    • 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
