R451 Mid-Reach Road Caliper

Even Super SLR brakes have a value line. These Shimano R451 road calipers are sure to have you stopping on a dime but not spending much more than a night out at a fancy restaurant. They're designed to work with Super SLR like Dura Ace Di2 7970, Dura Ace 7900, Ultegra Di2 6770, Ultegra 6700, 105 5700, and Tiagra 4600. They brakes have easily adjustable toe-in pads that are also replaceable, letting you get the perfect braking set up for your bike.

• Choose Front or Rear Brakes
• 47-57mm brake arm reach
• Use of these calipers with standard SLR enabled STI and brake levers results in a "mushy" brake response
