The Box Three V-Brake are made from cold forged aluminum for high-strength and low-weight. The two compound pads have a finned design for better airflow to keep the heat down under hard braking. The tension screws take a simple Philips head driver to make pad adjustments nice-n-easy. These are the brakes to get if you're looking to break into the realm of high-quality brakes that won't totally break the bank.
