TRP-12

TRP. 12 Speed. I thought they just did brakes...

It’s safe to say TRP are best known for its brakes, but the cycling component specialist has now entered the 12-speed mountain bike drivetrain market aimed at the Enduro and Trail market. 

This new TRP12 shifter and derailleur follows the design trends first seen last year, when TRP debuted the DH7 downhill drivetrain.

But no Cassette and Chainring I hear you ask. Well, it has been produced to be compatible with a diversity of SRAM, Shimano, SunRace and e*thirteen cassettes, chains and chainrings. They have designed the new TRP12 to be silent while smashing the trails.

Damn it’s light!! Featuring a carbon-fibre cage and upper structure, with the remaining bits being forged aluminium, TRP claims a 282g weight rating for its new 12-speed derailleur  

The TRP derailleur will work with cassettes sized 9 to 50t in size and isn’t just a pretty face. TRP’s engineers Know that chain slap is so frustrating when speeding over technical terrain. But worse... dropping a chain!!! 

How did they stop this? The drivetrain’s noise factor, and keeping the chain securely in place, is TRP’s Hall Lock. This is a tightening lever adjusting the TRP12’s mounting tension by pressuring the B-knuckle, preventing the derailleur from bouncing around its own pivot point. This was a feature named after the mechanic that designed this tasty little leaver! 

Beyond the Hall Lock, TRP’s 12-speed derailleur features a clutch system, similar to SRAM and Shimano’s drivetrains, to optimise chain tension. TRP’s clutch has a ratchet mechanism, instead of using a friction plate.

The shifter has been designed with ergonomics in mind and has 40-degrees of lever adjustability, So you can really choose the perfect placement for you fast shifting thumb!  TRP’s 12-speed shifter is claimed to weigh only 120g.

Want it!? Well it’s not the cheapest, but I guess not the most expensive. In my eyes I would say yes and maybe a future purchase. They can be purchased individually or together. Together £330 (no brainer as you would want both) or £120 for the shifter and £240 for the Derailleur.
