Bones Kitty Twister V5 Sidecut STF Wheels 99A 54MM

In 2005, we introduced STF wheels and changed the game. Offering a new formula for that generation, we forced wheel brands to look for ways to improve their offerings.

As BONES X-Formula continues to establish itself in the market as this generation’s premiere, hi-performance wheel, we have decided to offer our industry favorite Street Tech Formula, STF, at a mid-tier price.

STF became known as the wheel that rolled fast, gripped when needed, and slid when you wanted, providing more confidence without flat spotting. Outperforming and lasting several times longer than most other wheels made them the best for less.

Available in two durometers: 99A and 103A, STF remains an incomparable value at a new mid-tier price. Manufactured in our US factory, BONES Wheels is proud to be able to offer skaters quality wheels at all key price points.
