If you have ever noticed fast bikes generally have big brake discs because faster and/or heavier bikes need better brakes. Having a larger disc up front can be a life saver!
The extra stopping power is achieved simply by better leverage to the wheel. You might say I don’t ride fast so why do I need it? Because even if you don’t ride fast; the need to stop fast can happen at any moment and if your brakes aren’t able to stop you; all you can do is watch as you ride into disaster! Even at 70Km can be fatal. If it saves your life once it is money well spent. .
