SHIMANO BR-R451 Bicycle Brake Calipers

The Shimano BR-R451 mid-reach road brake calipers offer a versatile rim brake solution for cyclists who require extra clearance for larger tires or fenders. Available in a sleek black finish, these calipers provide a perfect balance of light action and accurate braking power. They are an ideal choice for road, touring, or urban bikes where standard short-reach brakes do not provide enough vertical height.
