    6 Bolt International Standard

There is a problem with some disc rotors on the market. The rotors are cut out in the bolt area and do not have a reinforced center to properly support the international 6 bolt mounting system. The cut out rotors are weak at the bolts and result in failures. Bill Shook engineered the disc reinforcing ring to support the 6 mounting positions, effectively tying them together to work as a unit. Can be used on other hub brands. An ingenious technical solution to improve your riding. When you see the red disc reinforcing ring, you know it’s AC. (patent applied)
