This lightweight model is a perfect solution for riders who want to take advance of some of the best Shimano technologies at an affordable price. Technologies: Dual-Pivot Caliper: A lightweight, compact and durable braking system. Dual-pivot caliper brakes have made considerable progress in the reduction of tolerance and deflection as well as in durability. They have achieved a firm and instantaneous braking response while assuring longer service life. Moreover, the brake pads have improved the durability of 100% to help enjoy high-response braking over longer periods. 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 Servo Wave mechanism is adapted to provide quick contact of your shoe to the rim and longer stroke from the initial braking effect for better control. SLR is the essential factor in the Shimano dual-pivot caliper that delivers more braking power than conventional side-pulls. Click here to view the Shimano Brake Reference Guide.
