Review on RADECKAL Black Mamba ABEC 9 Skateboard Bearings: High Precision, Long Lasting & Pre-Lubricated for Skateboards, Longboards, Cruisers - 608 RS with Built-in Spacers by Johnny Nguyen

These are great longboard bearings as the built in spacers are great and the spacers fit perfectly on every wheel I've tried! This means you can tighten them all the way and loosen them just a little and they will be perfect! Spacers are a MUST for any style of downhill/freeride longboarding, especially if you plan to slide when standing sideways and all the power is on the wheels and bearings. It's these spacers that keep your bearings from exploding! Overall great camp. For a long time if not beaten!
