Shimano Ultegra BR-6800/6810 Road Brake Calipers

• Compatible with STI and brake levers that are SLR-EVO or Super SLR enabled (e.g. Dura-Ace 9000, 7900, Ultegra 6800, 6700, 105 5700, Tiagra 4600)
• Enhanced brake arch proportion for quick & predictable linear response
• Spring tension adjustment for custom brake feel
• Adjustable toe-in shoes with R55C4 pads
• SLR-EVO dual symmetric pivot brake caliper
• Short arms and dual bearings reduce friction at the pivot area
• Use of these calipers with standard SLR enabled STI and brake levers results in a “mushy” brake response
