System engineering at its peak. Each of the components magnifies the qualities of the others for an unparalleled level of performance. Optimizing input to maximize output. That's how it achieves supremacy.

Features 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. And we offer 2 axle symmetric brake caliper and fork mount and chain stay mount type (BR-R9100/6810/5810).
