Review on 🛹 SKITCH Pro Skateboard Bearings - High-Precision Fast Spin ABEC 9 Chrome Steel Kit for Longboards, Skateboards, Scooters, and Roller Skates + Spacers, Washers, BONUS Carry Case (8-Pack, Black) by Tim Roby

First Impression The fact that the bearings have two nylons protects them amazingly, it increases the "clean life" and extends the life of the bearings. Accelerator rings (discs) don't look like precision rings, but that's just a visual impression, I haven't measured. When using the bearings, without long training but due to a small injury in the middle of training, I felt that the bearings are fast. I hit 17 mph at the same points in my daily route where I normally hit fast speeds (around 18-19 mph.hour), but I wasn't expending normal energy, so I think I can go faster with that . While I liked the bearings I can't comment on the durability now as I'm not a skater so I have to put more miles on them (only 13 miles so far) to speak about them.
