The Shimano Ultegra BR-R8100 side-pull brake impresses with a clear contact feeling and a well-balanced ratio between braking power, stiffness and low weight.

The brake caliper owes this to a sophisticated Dual Pivot construction as well as SLR-EV technology. Despite increased 28C tyre clearance, the rim brake features a decidedly slim design.


SLR-EV - The SLR-EV technology extends the Shimano Linear Response concept which aims for improved response and optimal dosing.

Symmetrical Dual Pivot side-pull brakes with SLR-EV system use two bearings and a roller to achieve greater efficiency in the joint area. However, SLR-EV also has a positive effect on the modulation of Direct Mount calipers, so that current models can boast a 36 % increase in braking force.
