The Shimano BL-R400 brake levers have an ergonomic and aerodynamic design that will adapt perfectly to the shape of your hands to prevent them from getting numb. These brake levers are specifically designed for road or drop bar handlebars and are compatible with all double-pivot caliper brakes. Thanks to their SLR technology, which keeps the brake cable under greater tension in order to avoid possible friction, they will guarantee easy and effective braking so that you can fully trust in your bike\'s braking performance.
