Road Bike Brakes are specifically designed to fit carbon, alloy, steel and titanium frames of road bikes with standard mounting points or the new direct mount points. Shimano brakes are specially designed to work with shimano brake levers and offer plenty of stopping power in both dry and wet conditions.
With Dura Ace BR-9000, Shimano introduced the new Real Dual Pivot road brake calliper. That technology has now made it's way to Ultegra BR-6800 and 105 BR-5800 series.
Most recently, some manufacturers have added direct mount points to their frames. Shimano Dura Ace BR-9010 are specifically design to fit those frames.
