The Rant Party Guards are designed to work exclusively with the Rant Party On V2 and Moonwalker II wheels. Made with a fast sliding and durable nylon composite, they work hard to keep your hubs safe. The guards and rear simply slide on the existing hardware – no need to remove cones. The drive side guard is specific to the hub type and includes a cone to replace the existing cone allowing the guard to slide on Moonwalker II or Party On V2 hubs. All guards maintain the hubs width spec, so no frame stretching is needed.
