Ultegra R8100 - Leave Time Behind

When developing the Ultegra R8100 series, Shimano took a holistic and 100 % performance-oriented approach, because great speed means great responsibility. Faster than ever before, the 12-speed road groupset scores with unparalleled control and comfort anytime and anywhere - whether in an everyman race, on the hunt for a personal best time or on a companionable ride.

Shimano Ultegra BR-R8100 rim brake

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.
