Staying loyal to the innovative history of the brand, the Atlas Blackout Bearings aren’t just your average built-in bearing.
When axle nuts are tightened down the result is often compression of the interior bearing spacer. This puts stress on your bearings and introduces slop into your setup, detracting from the precision that a bearing spacer is intended to provide.
The flared spacer built into the Atlas Blackout Bearing increases the surface area of the load bearing foot between the two bearings. This provides additional support and prevents compression of the spacer giving Atlas Blackout Bearings a more precise ride, faster roll speed and a long lasting life.
