ACS was the first company to com out with a “free-coaster” specifically for freestyle BMX. Released in 1986 it was named the ACS “RL hub” named after legend rider RL Osborn who had a hand in its design. It uses modified Suntor internals. The hubs shell is sleek and quite nice. The only real problems that Rob Ridge, and others in the early days of free-coasters, were:
- Bent axles created major problems (as with most free-coasters)
- The cones could not be adjusted much differently than they were stock.
- In order to get inside of the hub, you need a special tool (which could be made fairly easily)
