Shark Wheel California Roll 60mm 78A Wheels, Red + Shiver Abec 7 Bearings

I put them on my new skates to commute through rough asphalt. They work well over gravel compared to another set of outdoor wheels that I have. I would like to see a narrow version if possible. I also have a set of these on one of my longboards. The bearings are good so far. I didn't need to add additional lubrication and the wheels spin well. I don't understand the obsession with name brand bearings. These are a great value.I have not tested these at the skate park. I will probably not use them there because I imagine that the wavy edge will not make for a pleasant grinding experience.
