Safety is the biggest advantage of disc brake road bikes. However, disc brakes do not only improve the safety. Sure speed and performance can come from aerodynamics, but it should be noted that efficient braking can also lead to an increase in speed. Therefore it was no surprise to see Romain Kreuziger win Ötztaler 5500, the professional race with the most altitude meters on a disc brake bike (Addict RC disc).
We think it is important to improve the safety of cyclists and this is possible with disc brakes without a compromise on the overall performance of a bike. Better brakes, better acceleration, improved aerodynamic wheels out weights the minimal extra weight of disc brakes.
