This is the Hope Tech 3 X2 Rear Brake Set. Hope have kept the key features of the Tech Evo master cylinder and worked to improve the ergonomics and integration on the handlebars. The Tech 3 master cylinder can operate all the calipers from the range and offers a slight increase of power of about 5% over the Tech Evo. Popular design features of Tech Evo remain the same, such as the reach and bite point control (BPC)adjustability. The piston is actuated by a cam and a roller system to eliminate any free play and initial friction. The classic split clamp design makes the master cylinder easy to install on the handlebars without having to remove anything else.
