Bones - Standards 52mm STF V1 99a Wheels

Built for speed, durability, and precision control, the Bones Standards 52mm STF V1 99a Wheels are engineered for serious street and park skating. Designed using Bones’ legendary Street Tech Formula (STF), these wheels deliver the perfect balance of grip and slide while maintaining exceptional resistance to flat spotting, giving riders a smoother, longer-lasting performance session after session. STF urethane is specifically developed to roll faster and last longer than standard skateboard wheels, making it one of the most trusted formulas among professional and everyday skateboarders alike.

The V1 Standard shape offers a classic, well-balanced profile with the ideal combination of width, riding surface, and speed. This shape provides reliable control for technical street skating, ledges, rails, and park transitions while maintaining predictable slide characteristics when needed. The 52mm diameter keeps the setup lightweight and responsive, making it perfect for flip tricks, technical street skating, and skaters who prefer quick acceleration with excellent board control.

With a 99a durometer, these wheels sit at the sweet spot between speed and versatility. They are hard enough to maintain fast roll speeds and clean slides at the skatepark while offering slightly more forgiveness than ultra-hard formulas, helping absorb minor roughness on street spots and imperfect surfaces. This makes them an excellent choice for skaters who move between park and street terrain.

Bones STF wheels are renowned for their high rebound urethane, allowing them to maintain speed and responsiveness even after heavy use. The advanced formula ensures they resist flat spotting far better than most traditional skateboard wheels, extending their lifespan and maintaining consistent performance over time.
