Brake and gearshift function for easier system operation. The internal components of the lever are robust and operate so smoothly and lightly that it is possible to change the front and rear gears with just one finger.

The SLR-EV is an SLR with a double symmetrical pivot caliper. The short arm brake design has two bearings and a pulley to increase the lever ratio and provide control and braking power. The short arm reduces friction in the pivot, promoting quick response and high performance. The double bearing and single roller design improves performance at the pivot point.
