BankRoll X4 outdoor wheels are made for the streets, sidewalks, concrete, and asphalt. These wheels have a durometer of 78A and roll smooth on rougher surfaces. BankRoll X4s are specifically made to be durable, reliable, and smooth on rough surfaces. Currently sold in black only and pictured here with Bankroll Dimes bearings (sold separately). This wheel is 62mm. Bankroll X4 wheels resist dirt and grime and are easy to clean. These wheels will work with any modern skates with 8mm axles and bearings — that includes Moxi, Sure-Grip Boardwalks, Jackson Vista, Riedell and many more. This wheel is a great way to tone down bright colors on skates as they are the antithesis of color. The wheel is almost matte black, but it does have a slight sheen. They work great for “blackout” look or to bring a little more masculinity to a colorful skate. Bankroll X4 wheels are sold in 4 packs.
