Rippin`trails like there is no tomorrow. The new TR12 drivetrain system brings World Cup downhill shifting technologies to the trails. TRP is expanding its product line with a new 12 speed shifter and derailleur.

The two TRP drivetrain systems, TR12 and DH7 are the result of an intimate development relationship with 5 x DH World Cup Overall Champion Aaron Gwin and his personal mechanic John Hall. Along with the input given from Team Intense, Scott DH, Commencal 100% and YT Mob. In 2019, the TRP DH7 had over 300 racing days. This extensive first season was crucial for providing additional development input for the new TR12.

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 or closed to balance the stability and security of the system while deflecting impacts.

This key feature was born from an ongoing competition amongst the best mechanics on the Downhill World Cup circus to build the quietest bike on the track. John Hall identified the movement of the derailleur around the B-knuckle as a key point of improvement for several reasons, which are punctuated by removing the noise caused by chain slap and increasing shifting accuracy. Features well appreciated for rough trail riding.

A second key TR12 derailleur feature is an adjustable ratchet-style clutch. Depending on the suspension layout of the bike, there can be different amounts of chain growth. This is why the team designed adjustability into TRP‘s ratchet style clutch. If a rider wants to free up the system, they can back off the clutch to balance pedal feedback with chain retention. This provides the ultimate personalized feel as the drivetrain works in unison with the suspension set-up and riding style.

“Take a chance on it, it is pretty cool how the product grows and becomes yours – you’ll be blown away.” John Hall.
