STF (Street Tech Formula) is for those who don’t take any compromise between slide and smooth roll. This ride shines on the streets and will rip the park any day. The V5 shape keeps good grip/slide ratio, looks cool and beefy, and lasts extra long.
The Bones STF is good for crusty street action. Nice and hard, exceptional flatspot resistance, crisp sound. If you are into powerslides, you’ll have a lot of fun on these. Like other Bones premium wheels, these never go yellow. Overall, it’s a top quality all-around wheel that’s best for street and can be used for park. In addition, Bones STF 99a are as durable as the original STF formula that’s known to last. SPF’s are versatile, stable, durable, and will provide riders with best all around performance!
Bones Wheels has created a wheel with a substantially higher rebound for more speed and amazing slide capabilities while maintaining a resistance to flat spotting well beyond any standard wheel. Set those up and go test any street or park. Skate everything!
