Magura MT5 Next Disc Brake. If it's stopping power you want, it's stopping power you'll get with the Magura MT5 Next Disc Brake. Magura has taken motorcycle racing's proven four piston technology provider of maximum braking force and adapted it for mountain bike use. The disc brake's four piston caliper and new ergonomics in the brake lever will instill a remarkable sense of confidence when you head out on the trails. The aluminum, two finger brake levers enable you to easily and accurately apply the braking power you need, even during long braking actions on extended downhills. Additionally, Magura's use of Carbotecture technology in the brake handle housing keeps the MT5's weight down to a minimum for optimal braking performance.
