Bones Street Tech Formula V1 Skateboard Wheels

A 99A durometer is a classic street hardness. It offers a balance of grip and slide, making it firm enough to slide easily on ledges and rails while still providing enough traction to control your board on concrete.

The V1 shape is the traditional, versatile profile. It features a standard width and rounded edges, which makes it predictable and stable for technical street skating and flip tricks.

While these wheels are engineered for performance on smooth concrete and skateparks, the 99A hardness is standard for street use. If you primarily skate very rough asphalt, you might find a softer wheel provides a smoother ride, though you would sacrifice some slide capability.

Yes, Bones' proprietary Street Tech Formula is specifically engineered to resist flat-spotting. It maintains its shape and performance integrity significantly longer than generic urethane, even under the stress of heavy power sliding.

53mm is a very popular, middle-of-the-road size. It is large enough to maintain speed and handle minor cracks, but small and light enough to keep your setup responsive for technical maneuvers.
