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 aluminum rim linings.
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 for a more comfortable ride on rough surfaces.
TECHNOLOGY:Dual-Pivot Clipper:

The design makes the brake system lightweight, compact and durable. The Dual-Pivot Clipper Brake significantly reduces warpage, increasing tolerance and durability. It reacts strongly and instantly, while maintaining a longer service life. In addition, brake lining life has been extended by 100%, so users can enjoy high braking performance for a longer period of time.

SLR-EV:

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 braking 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.
