From Concentrate Hardline 101A Skateboard Wheels 4-Pack

The 4-pack OJ's From Concentrate Hardline wheels are suitable for skateboards. Built from high rebound urethane, these wheels will give you a great feel under your feet. The wheels are cast with Super High Rebound (SHR) PU-rubber and are therefore particularly suitable for skateboarding. The small 52 mm wheels are your street setup for pop and good balance. Whereas the medium-sized 53 and 54 mm wheels will serve you as an all-arounder for street, park and small ramps.

With the hard durometer of 101A, these OJ's wheels are great for performing tricks and smooth slides and grinds.
