Firstly it stops damage to the suspension components but also it allows the suspension to perform at its optimum. A freshly service fork has significantly less friction than a fork requiring a service. The reduction in breakaway friction improves small bump sensitivity, which translates into more grip with less fatigue which allows you to ride faster for longer. This is important if your racing or just riding for fun with your riding buddies. Prices for our services can be found here for
