Thru-axle mount, rear brake caliper
Braking should be progressive, powerful and smooth. Shimano brings all these features to the BR8100 caliper.
David G.
Former professional team mechanic
The Shimano caliper incorporates the latest braking technologies from the leading bicycle equipment manufacturer. It features SLR-EV technology with a symmetrical dual pivot. This increases braking power and efficiency by approximately 36% compared to the previous generation of Shimano brakes. The shape of the caliper and its dimensions allow for the use of tyres up to 28mm wide. It retains a smoothness, power and precision rarely achieved in this Ultegra range.

Very good product that I have been using for over ten years without any problems. This chain is mounted on a Super Record Campa group and I complete a full year with each chain (between 7 and 10,000 km). The transmissions are smooth and maintenance is facilitated thanks to the quick link. I recommend. (Translated review)
