I own a pair of Bauer 20-50 roller hockey skates. They have the single axle single screw set up for the easier replacement of wheels, bearings, and the tightening of wheels, etc. Are the Sonic Long Sleeved 608 Bearing Spacers compatible with these single axle (plates) ? Or do I have to buy a Boss BSB Single Axle Inline Skate Kit?
