TEKTRO, the parent company of TRP, has published a patent detailing a new rear derailleur design that is a Direct-Mount Derailleur, mounting onto the dropout co-axially with the hub axle. The patent aims to improve the stability of the bicycle rear derailleur to resist an impact or a shock. The design has similarities with SRAM's T-Type Eagle Derailleur and Shimano's Patented Direct-Mount Derailleur. TRP's Direct-Mount Derailleur has a single arm that sits outboard of the dropout and can be removed from the frame without removing the rear axle. The patent document makes no reference as to whether or not this derailleur would be electronically or mechanically actuated.
TRP has released its first full groupset, the EVO, which includes a new crankset and cassette. The groupset is available in 7-speed or 12-speed options and is designed for enduro, trail riding, and downhill racing. The shifter and derailleur have been updated for improved ergonomics and shift accuracy. The Hall Lock feature prevents derailleur movement in rough terrain. The groupset will cost $1,343 for its cheapest spec and is expected to launch in April.
Taiwanese brand TRP has released its new EVO12 and EVO7 complete drivetrains, which include two new derailleurs, two shifters, carbon and aluminum cranks, and two cassettes, all of which are intended to compete against the best mechanical options from Shimano and SRAM. The EVO12 derailleur features a Hall Lock to prevent floppy derailleur syndrome, while the matching shifters have a hidden switch to choose between single or multi-shift modes. The new cassette is a two-piece design, with the first ten cogs being machined from a single piece of forged steel and the two largest cogs in aluminum.
TRP is launching its new EVO7 and EVO12 mountain bike drivetrains in April, with the EVO12 aimed at the XO/XTR Trail level. The drivetrain features a complete group, including cranks, chainring, and cassette, and is designed to work with TRP's brakes. The EVO12 derailleur has a stiffer body, linear parallelogram actuation, and a Hall Lock to steady the derailleur body. The shifter has a more compact design and reduced small parts, while the cassette is a two-piece construction that comes in 1g lighter than XX1 and 2g lighter than XTR.
