Shimano 105 R7120 Mechanical 2x12 Speed Shifter Set

Function and technologies inherited from Dura-Ace and Ultegra, Shimano 105 is the culmination of years of research and development. Shimano 105-optimized gear combinations, and an exceptional brake system, the new Shimano 105 marks a new era of affordable performance.

A compact R7100 series shifter that keeps you in control in any situation. The difference is made over the course of a ride, saving you energy with every gear change, allowing you to focus on the scenery, your effort, and your friends.

The all-new lever shape brings comfort and control in every riding position. Raised hood peak improves ergonomics, while a longer hood body increases hand support. Compact, ergonomic performance, custom button function and adjustable ergonomics cascaded from Dura-Ace.

With a new piston design, race-ready braking is now available for even more riders. The new Shimano 105 BR-R7170 brake caliper allow riders to progress in their cycling journey by learning the joys of braking and pushing their limits with better sensitive braking control in a wider control zone and 10% wider pad clearance.
