Shimano 6700G Brake Front/Rear Set
The Ultegra BR-6700 dual-pivot brake calipers feature enhanced arch proportions and a super SLR design for quick linear response and increased rigidity. A cam in the brake lever provides mechanical advantage and modulation to further enhance braking power. With new pad compounds, braking power is increased by 20% under dry conditions and doubled in wet conditions. Low-profile outer cable stop position improves cable routing for reduced friction, while spring tension adjuster allows a precise set-up.
These breaks are strong, they are pure quality breaks and function as good as dura ace, they are just a bit heavier. They are smooth and you always have the right feeling of the break. You can adjust them very easily with the barrels, they have the ratchet thing to open the calipers when needed and also have the centering screw with is perfect. It doesnt get much better than this. Five stars.
