SLR-EV
SLR-EV is SLR with a dual symmetric pivot brake caliper. The short-arm brake design employs two bearings and a roller to realize greater efficiency in the pivot area and deliver superior modulation and power for braking. Together with the BC-9000 brake cable, the latest calipers deliver 36 % more braking power than SHIMANO’s previous brake model.

DUAL CONTROL LEVER
