Dura-Ace delivers concentration control and confidence with slick fast accurate performance that you can depend upon without distraction. Dura-Ace now has an 12 speed cassette with numerous gearing options to cover all situations. Leading edge design materials and construction reduce weight improve stiffness and enhance control.
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.
