TRP EVO12 Rear Mech

The Power of Choice Introducing EVO12 and EVO7. The embodiment of EVO and the culmination of TRP's extensive engineering and development history integrated with the world's top riders and teams. EVO means we have made advances to our first-generation features such the Hall Lock, silent clutch and cage release to improve performance and usability. The Hall Lock all but mitigates drivetrain noise to help riders stay focused and undistracted. EVO12 and EVO7’s instant, silent clutch tames unwanted chain slap and further quiets the entire shifting system. The cage release makes wheel removal a pleasant task. Couple these innovations with the all-new shifter design featuring improved ergonomics and a shift mode switch to allow riders the choice between one upshift per click or a sweep of up to five upshifts per click and you have a shifting system that is quiet, precise and efficient. Finally, carbon or forged alloy crank arms are mated to 1 x chainrings with Wave™ tooth profiles to hold the chain securely over the roughest terrain. Explore EVO12 and EVO7 and feel the power of choice.
