BankRoll Dimes are awesome bearings for any skate with wheels including inline skates, quad skates, and skateboards. These bearings are rated “ABEC-9”. Just like many other bearings on the market, these bearings fit on 8mm axles and have an extremely smooth roll. These bearings are easy to clean, long-lasting, and durable. Bankroll bearings are ready to go out of the box — no “break in” time necessary. They are high quality, affordable, and recommended often by the Devaskation team! Speed skaters should upgrade to BankRoll Ceramics.
