Aero Pro’s bushings are 90A medium rebound tall barrels. The height is 18mm, similar to tall barrels from Venom and RipTide Sports (0.75 inch or 19 mm but not always).

Shorter bushings may be used on the road side. If using shorter bushings on the board side, stack flat washers to make up the height difference. The number of washers needed vary depending on their thickness.
