Now that we have learned more about braking with BrakeAce, there are a number of things we can do to improve the performance of our brakes.
One of the best things we can do to get better performance from our brakes is to have larger rotors.
The reason for this is that every time we use our brakes, we are removing energy from the combined kinetic energy of ourselves, our bike and our speed.
This energy is transformed *mostly* to heat, which builds up in our rotors and pads. Too much heat and we lose performance of our brakes, since beyond a certain point, the coefficient of friction between the pads and rotors will reduce. Beyond this, we get a boiling of the pad material or even brake fluid. These are obviously not ideal!
Larger rotors have a greater mass and allow for greater storage of heat. This is good because if there is a greater capacity for heat in the rotors, your brake pads and hose fluid can stay at operation temperatures. We have tested rotors from 180mm all the way up to 246mm and 2.3mm thick!
Furthermore, the larger rotors have a greater area, which means that heat can also dissipate more quickly.
Listen in now FIVE reasons to try larger diameter rotors.
