In an unexpected road situation, riders often can’t react fast enough to decide which brake lever to pull. The DOUBLE CBS system allows you to stop the bicycle by pulling hard on just one lever. The rider only has to use a single level to brake the rear wheel first, then the front wheel. Through extensive experimentation, our research and development team has found the perfect ratio of energy for front-braking (70%) to rear-braking (30%) with a single lever. This allows the cyclist to brake both wheels easily in an unexpected event.
