To rear brake or not to rear brake? That is the question



One of the awesome metrics BrakeAce shows you is your Brake Balance. This is the proportion of braking that was done with each brake in terms of total energy (kilojoules). It's an incredibly valuable metric, and everyone is always asking if they should be using their front brake or rear brake more.


So what is the answer? Front brake or rear brake?

Front brake, back brake, or both? c Tyler Perrin

Since MTB disc brakes were invented, bike companies have always stocked a larger front rotor and smaller rear rotor. It makes sense because we can stop more effectively by using more front brake. The issue here is that when we're riding, we're not stopping - we are riding, moving and going fast!


Our original scientific research showed that beginners were highly reliant on the rear brake, and that experts used the front brake more than beginners. This was around a controlled turn, with no chain and controlled speed heading in to it. The beginners braked for a longer time and used more rear brake.

Once we developed BrakeAce, we found that on technical trails, almost all riders tended to favor the rear brake more. Some riders were 40f/60r, some were 10/90, and in rare cases, 50/50.
