Shimano Tiagra BR-4700 Rim Brake Caliper

The Shimano Tiagra Dual-Pivot brake caliper provides consistent all-around control. Compatible with 28mm tires, the caliper uses a thrust bearing pivot to reduce friction while new, toe-in adjustable brake shoes improve braking.

Technology

New Super SLR

SLR stands for Shimano Linear Response. The new super SLR design makes use of a friction-reducing mechanism in the caliper, lever and cable that improve response and modulation.

Also for the lever, the Serowave mechanism is adopted to provide quick contact of shoe to rim and longer stroke from the initial braking effect for better control.

SLR is the essential factor in the Shimano dual-pivot caliper that deliver more braking power than conventional side-pulls.

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.
