In addition to the advantages of the ST-R8000, the ST-R8020 combined with the hydraulic disc brake offers an additional bonus: a higher level of control for the rider, regardless of the conditions. The small size of the mount feels great in the palms and improves ergonomics. The hydraulic disc brake caliper BR-R8070 provides an even higher level of control, allowing riders to benefit from maximum braking performance under all conditions. Its sleek design ensures seamless integration into the profile of your bike.
