Avid is a sunsidiary of SRAM and was started in 1991 with the concept 'Small Details. Big Difference'. Avid works hard to bring the most dramatic improvements and make products so good you find it hard to ride without it. The Avid Bleeding Edge Quick Kit makes bleeding brakes quick and simple. The new fluid path and bleed porting makes it easy to push fluids through the caliper. A dedicated bleed adapter plugs into the bleed port and seals the system to minimize air contamination and fluid loss.
