Shimano BL-RS600 is a group-free brake handle (no change function!) designed to be used with the Road Flat Mount brakes. Your 3-finger brake lever provides a lot of comfort in daily use. It also contributes to a stable braking function with its optimized braking force curve. The I-Spec II fixation for the integration into space of a suitable change handle (e.g. SL-RS700-I) will make you as much as simple installation and simple purge by means of funnel.
