The New J4 Wheels, the G4 shape combine with the material from the Jay Linehan's Signature Street Shape Wheels create the J4s!

The long awaited Jay Linehan Pro Wheel is back! Featuring the FlatFace G4 design and a 100% unique material. These wheels are a slightly off-white compared to our regular white wheels, and a bit softer without being too grippy! The material gets darker with use, just like a real skateboard wheel. These are epic!

FlatFace wheels feature real miniature ball bearings, just like a real skateboard wheel. These fit all trucks, but are specially designed for optimal performance and durability with blackriver trucks.

These wheels have a specially designed bearing system so that they will run smoother and faster on Blackriver trucks than any average wheel on any average truck. You won't experience this smoothness anywhere else. Made with special high quality classic white material and steel bearings, these wheels are also designed with skaters in mind and has incorporated super tiny ridges into the riding surface exactly like a real skate wheel for a bit more grip.

These are more grippy than other FlatFace wheels but they are not urethane, and they are harder and less grippy than urethane. These Jay wheels are are slightly harder and slightly less grippy with a smoother feel.

Note:
FlatFace Single Bearing wheels are specially designed to work with Blackriver Trucks and also work with other trucks such as Bollie Trucks and Ytrucks(if you purchase FBS Ytrucks Spacer).
