Avid makes it easy to get a perfectly set up brake with their innovative CPS Hardware Kit. Each kit features a series of washers that allow the caliper to move as you install your brake. Step 1: Install the bolts and washers loosely so the caliper can move. Step 2: Squeeze the brake lever. Step 3: Tighten the bolts. It's that simple to get excellent caliper alignment! This kit includes ultra-light titanium hardware with washers for CPS (Caliper Positioning System) mounting.
