I've got two old school reissues set up with slightly larger wheels; Bombers and Rat Bones. They are loaded with Reds Race Bearings and some Black Panther Ceramics. Those boards just glide and I pick up speed when I'm cruising really fast. I only skate my popsicle at the park, and I have it set up with some slightly smaller Bones 100's (55mm I think) and Bones Reds. I have had trouble getting the speed I want in the bowl but chalked this up to me just now getting back into it. I started skating it on the street and noticed that it's significantly slower. All my bearings and wheels are still pretty close to new at this point. Is this likely due to harder wheels, or the bearings?
