The new wireless brake shift lever has been redesigned in collaboration with professional riders and impresses with its raised horn and lighter lever operation, providing outstanding ergonomics. The adjustable grip width mechanism allows customization for various hand sizes and riding styles. Additionally, the braking area has been expanded for improved control. The new hydraulic brake caliper features a 10% wider pad spacing than the mechanical 105 model, resulting in reduced brake drag and consequently less noise. Furthermore, maintenance efforts are lower due to the bleeding process.
