Magura MT8 Next Disc Brake. When every gram counts, the Magura MT8 Next disc brake is the ultimate choice for that featherweight cross country bike. The MT8 is Magura's lightest disc brake yet still delivers their renowned uncompromising braking power. The full carbon fiber, two finger brake lever combined with the Carbolay handlebar clamp are a marvel of ergonomics and high performance. Tool less adjustment of lever reach and bite point makes it a simple process to dial in your personal preference while the forged aluminum, two piston caliper is exceptionally tough and light.
