A2 Cushion Roller Kit Hub

Do you have issues with the lower hubs coming loose on your A2 cushion roller kits? Other kits on the market use a separate hub and sleeve combo which is prone to wobbling and loosening itself over time. This upgraded lower hub integrates the "spacer" into the hub design, leading to one solid part that won't loosen over time. Currently sold as the hub only, full kit will be available soon.
