We start with high-grade steel ACB (Angular Contact Bearing) sealed bearings which feature precision ground-hardened steel balls. What does that mean to you? Probably not much. But know that these bearings will last a long time thanks to this seemingly minor design choice!

We add on a quality CNC'd Aluminum top cap, followed by a thin rubber dust seal to maintain the life of the bearings. The Bottom Aluminum race is split to allow easy installation and removal without any tools!
