The Shimano Dura-Ace R9100 is a completely redesigned road groupset aimed at professionals. Every component has been designed from the ground up to create the most innovative drivetrain of all time.

Dura-Ace BR-R9100 road brake

• 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.
• Standard equipped with R55C4 pads with replaceable linings.
• Adjustment screw makes it easier to accurately position the pads relative to the rim.
• More space between the arms and the tire.
• Despite its 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:

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.
