Long fast descents demand confidence. Dura-Ace R9100 brakes deliver with a new symmetrical dual pivot design and twin bearings reducing pivot friction and improving efficiency and controllability. 10% more power than BR-9000. Smooth and light operation with increased modulation. Along with new low-friction BC-R9100 cables Dura-Ace brakes give smooth light operation with excellent modulation. The all-new 2016 Dura-Ace group is the result of 40 years of development and innovation tested to the limit at the highest level of competition in road racing time trials and cyclo-cross.

Dura-Ace delivers concentration control and confidence with slick fast accurate performance that you can depend upon without distraction. Dura-Ace now has an 11 speed cassette with numerous gearing options to cover all situations.
Leading edge design materials and construction reduce weight improve stiffness and enhance control.. Front and Rear Calipers are included. 290 grams / pair.
Rim brakes for bikes use the sidewall of the rim to reduce speed this is done by a pad on either side applying friction against the rim which reduces your momentum. Road brake calipers have been redesigned over the years and now use a system called 'dual pivot' which means the brake arms pivot off center to apply a higher amount of pressure on the rim to increase your stopping power. Most manufacturers use dual pivot calipers on the front and rear but some Campagnolo brakes use a traditional single pivot on the rear to 'balance' the braking power the logic behind this is that as you brake your weight shifts on to the front of the bike and as much as 75% of the braking force is applied to the front.
Shimano are the makers of the world's most well known cycle component brand. Established in 1921 when the first cycle freewheel was forged. Shimano produce drivetrains wheels pedals shoes cycling apparel and pretty much every Shimano cycle accessory.
