Mountain Bike Action Product Test: TRP TR12 12-Speed Drivetrain
Field test results:
We set up our drivetrain using a Shimano 10-45-tooth cassette and chain, along with a Hope components crankset. Setup was straightforward, and the printed indicators offered needed assistance. Getting the system shifting smoothly in the stand required little effort and allowed us to quickly hit the trails. With both the Hall lock and Ratchet clutch engaged, the system is nearly silent and offers crisp shifts between each gear. The shifter shape felt ergonomic but took a little time to get used to after years spent riding Shimano and SRAM drivetrains. Shifting to an easier gear felt great, while finding harder gears required us to search for the lever.

The TR12 system seems ideal for enduro racers or trail riders looking to take on challenging terrain with a drivetrain they can trust. With technologies derived straight from the downhill DH7 system, the TR12 drivetrain is built to handle the roughest trails.
The ability to tune the derailleur is a feature racers will find most appealing. Since different types of bike suspensions can affect chain growth and shifting quality, TRP’s new system allows experienced riders to tune their drivetrains for the best possible feel. While the TRP12 drivetrain may benefit most riders, it’s gravity racers and hardcore trail riders who will see the greatest benefits from this all-new system.
