The Simson V-brake guide pipe with Power Modulator connects to the brake cable and the V-brake system at an angle of 90⁰ to each other. The power modulator ensures a good dosing of the braking force so the wheel is less likely to slip when the braking force is too high. Connect the outer cable to the brake pipe. Pull the inner cable of the brake through the brake pipe, and connect the inner cable to the V-brake braking system with an Allen key. The Simson V-brake guide pipe 90° is supplied with rubber.
