• Improved SLR-EV dual-pin design, for maximum precision and better control in a race.
• Made of durable and strong aluminum.
• Provides the perfect compromise between stiffness, braking power and weight.
• Dual SLR-EV stem.
• More predictable, linear braking force.
• Equal distribution of forces to both arms.
• R55C4 pads with linings for aluminum rims.
• Adjustment screw makes it easier to accurately position the pads relative to the rim.
• More space between the arms and the tire.
• Despite the slim and aerodynamic design, the spacing between the spokes allows a wide 28mm tire to be mounted, allowing a more comfortable ride on rough surfaces.

TECHNOLOGY:

The SLR-EV is an all-new SLR with a symmetrical Dual Pivot caliper brake. The short-arm brake design incorporates two bearings and a roller to increase the lever ratio and provide extraordinary control and stopping power. Together with the brake cable, the new pinch clamps increase braking power by 36% compared to previous brake models. The 2-axis symmetrical brake caliper and mounts to the fork and rear fork.
