Shimano Dura-Ace BR-R9100 Rim Brake Caliper

With Shimano’s SLR-EV dual symmetric pivot design, the short-arm Dura-Ace R9100 series caliper brakes employ twin
bearings and a roller to realize greater efficiency and deliver superior modulation and stopping power. They are
offered in traditional and direct mount options.

Technology

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).

Dual-Pivot caliper

The dual-pivot design realized a lightweight, compact and durable braking system. Dual-pivot caliper brake have
made considerable progress in reduction of tolerance and deflection as well as in durability. They have achieved
firm and instantaneous braking response while assuring longer service life. Moreover, the brake pads have an
improved durability of 100% to help enjoy high-response braking over longer periods.
