Description
The IIIPRO BR01 is a road bike cable-actuated hydraulic disc brake caliper developed for riders who want stronger braking power, smoother modulation, and a cleaner cable routing layout. This flat mount road caliper uses a dual-piston synchronous braking system, allowing both sides to push the rotor evenly at the same time for more balanced stopping power.
Unlike common brake calipers that route the cable on the outer side, the BR01 uses an inner-side cable routing design. This reduces one unnecessary bend in the cable path, which helps reduce cable resistance by approximately 30%. The result is a more direct cable pull, improved braking response, and a neater overall setup.
The caliper body is made from CNC-machined aluminum alloy for good strength, clean finishing, and lightweight performance. Based on the supplied product information, the brake pad compound uses a copper-based metallic lining, designed for strong braking force, high temperature resistance, and good durability.
The BR01 is also built around dual-piston synchronous braking. Compared with single-side braking designs, both sides of the caliper move together to keep the rotor centered more consistently, helping improve braking smoothness and reduce uneven friction feel.
This model supports 140mm and 160mm disc rotor setups with the correct mounting seat configuration. It is suitable for road bike flat mount applications and is offered here in black only.
For riders who want to get the best out of this braking system, S2HCYCLE strongly recommends pairing it with a 1.5mm polished inner cable such as OTR14. A smoother inner cable helps further reduce drag and improves overall braking feel.

Why Choose BR01
Many cable disc brake setups suffer from extra friction caused by unnecessary cable bending. The BR01 improves this by placing the cable routing on the inner side, helping reduce cable drag and delivering a more efficient lever feel. Combined with dual-side braking action and a hydraulic caliper structure, this makes BR01 a strong upgrade choice for riders looking for more confident stopping control.
