Bones STF V5 Wheels

A 99a durometer is considered a hard wheel, which is the industry standard for street skating. It offers the perfect balance of slide and grip, allowing you to perform technical tricks like power slides and reverts without sacrificing control on smooth concrete or park surfaces.

The V5 Sidecut shape features a wider contact patch and a slightly more conical profile compared to traditional shapes. This design increases stability during landings and provides a more consistent feel when locking into grinds, making it ideal for technical street maneuvers.

Yes, Bones uses a proprietary STF (Street Tech Formula) urethane that is specifically engineered to resist flat-spotting. While no wheel is completely immune to damage from extreme abuse, this formula is significantly more durable than standard urethane blends, even under heavy impact.

No, these wheels feature a standard centerset bearing seat, meaning they are compatible with all standard skateboard bearings. You can easily swap your existing bearings into these wheels without any additional hardware.

54mm is a versatile, mid-sized diameter that works well for most street skaters. It provides a good balance between acceleration and top speed, making it a reliable choice for both beginners learning the basics and experienced riders focusing on technical tricks.
