FlatFace has teamed up with Blackriver to offer you a unique, specialized bearing wheel optimized for usage 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 wont 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. 
All FlatFace Wheels are made of special compounds and many of our colours have slightly different feelings for more variety! The White Wheels are our signature D material, which has defined the standard for fingerboarding bearing wheels. They are very smooth and long lasting, great all around wheel for any surface, medium hardness and medium-low amount of grip for best performance on tricks.
