Suitable for most 16 inch and plus size wheels. It's a simplified and compact design purely for maximising the sensation and security at acceleration and braking. It's thick enough to fit even with big knee guards on. There no jump assistance so perfect for those heavy units that you won't get your feet locked in and it doesn't get in the way closing the pedals completely. Works flawlessly with S22 simply by removing the top pad and the boomerang.
