TRP EVO is a new mechanical 1x mountain bike drivetrain pitched as a premium option, going toe-to-toe with the likes of SRAM XO and Shimano XTR.
The outgoing TRP TR12 groupset only comprised a shifter and derailleur.
The groupset is available in either 7-speed (EVO7) or 12-speed (EVO12) options.
The 12-speed groupset is designed as an all-rounder option for enduro or trail riding. Like SRAM’s similar XO1 DH drivetrain, the 7-speed groupset is designed specifically for downhill racing.
The groupset will cost $1,343 for its cheapest spec and is expected to launch in April.
TRP’s first full groupset
Previously, TRP focused solely on brakes and limited drivetrain components. But the new cassette and crankset see the brand release its first full groupset.
The crankset uses a 30mm spindle and is available in either forged alloy or carbon options.
TRP has licensed MRP’s Wave tooth profile for the 1x chainrings used with the crankset. The drivetrain is also designed to use a third-party KMC X12 chain.
A single 10-52t cassette is available. The 10 lower cogs are machined from steel. The two largest are made from aluminium. This mounts onto a Shimano Micro Spline freehub.
Updated shifter ergonomics and a stiffer derailleur
TRP says the rear derailleur body and pivots have been strengthened. This is claimed to improve shift accuracy compared to the outgoing TR12 derailleur.
The Hall Lock is a feature unique to TRP drivetrains. Activating this locks a band clamp around the main mounting bolt of the derailleur. This prevents the derailleur from pivoting in rough terrain, which can exacerbate chain slap.
Deactivating it enables the derailleur to move freely, making for easier wheel swaps.
TRP has also updated the ergonomics of its shifter. The downshift lever can be adjusted to shift between one to five gears, depending on user preference.
The groupset will be on show at Sea Otter 2023, where further details will be announced.
