Upgrade your road bike braking performance with the IIIPRO BR01 cable-actuated hydraulic disc brake caliper. Designed with dual-piston synchronous braking, flat mount road compatibility, and support for 140mm / 160mm rotors, this caliper delivers stronger and smoother braking performance.

One of the key advantages of BR01 is its inner-side cable routing design. Compared with common outer-side routing, the cable path has one less bending arc, helping reduce cable resistance by about 30% for a cleaner pull and more efficient braking feel. For best results, S2HCYCLE recommends using a 1.5mm polished inner cable such as model OTR14.
