Bones STF Fatties 99a V6 Wheels

Bones STF Fatties in V6 shape are the kind of wheels that give you extra confidence under your board. “STF” stands for Street Tech Formula, Bones’ legendary urethane concoction known for insane resistance to flatspots and super high rebound. These particular wheels come in a 99a durometer, making them slightly more forgiving than the ultra-hard 103a’s, but still firmly in the street/park wheel category – so you get a bit more grip on slick surfaces and a smoother ride on rough ground, without losing slide capability. The “Fatties” (V6 wide-cut shape) means they have a wider contact patch and overall profile than standard. In practice, this gives you more stability and control, especially when landing tricks or skating faster – the wheels feel planted. The V6 shape also tends to be a tad lighter than you’d expect for a wide wheel due to cutaway design on the inner profile. These wheels are often about 54 to 56 mm in diameter (the common sizes for Fatties), striking a nice balance for street skaters who also hit the park or bowl occasionally. Centre-set hubs ensure even wear over time. Bones’ STF formula is practically synonymous with “no flat spots,” so go ahead and power-slide to your heart’s content – these can take it. In summary, Bones STF Fatties give you a wider, more secure ride for locking into grinds and cruising at speed, all while delivering the slidey, fast features that Bones wheels are loved for.
