Shimano BR-R451 Road Brake Calipers
  • Light action and accurate brake power
  • Adjustable toe-in brake shoes
  • Compatible with STI and brake levers that are Super SLR enabled (e.g. Dura Ace Di2 7970, Dura Ace 7900, Ultegra Di2 6770, Ultegra 6700, 105 5700, Tiagra 4600)
  • Use of these calipers with standard SLR enabled STI and brake levers results in a "mushy" brake response
