The Bones STF Wide-Cut 56mm Servold Contract 99a Skateboard Wheels are made with a substantially higher rebound urethane that is super flat spot resistant for more speed and awesome slide characteristics.
Urethane - STF 99a (Easy Streets Formula) BONES WHEELS Easy Streets are softer 99A Street Tech Formula wheels that ride smoother and faster on a greater range of terrain, without losing the unique grip, slide-ability and characteristic bark of our original BONES 103A / 83B STF. Easy Streets will improve your skating if you are not always riding super smooth concrete. They make it more fun to skate a wider range of terrains by cushioning your landings, gripping, sliding, and rolling easier on rough pavement…without flat spotting.
Shape - Wide Cut (aka V6 shape) It’s a wider wheel that can give you more slide control and more durability. It has sidecut walls for less drag on longer grinds and is a more stable shape for big gaps and aerial landings.
Wheel Size - The 56mm size is a great all-around park size to hold more speed in the flats and better momentum in the transition while offering a predictable pop, with a more stable lock into your grinds. A great size to max up your speed on all the park features.
The bearing core is centre-set so you can reverse the wheel to save the graphic or to maintain a longer life by rotating your wheel placement over the life of the wheel. This is handy when you slide your wheel often particularly in urban terrain that can wear your wheels in an uneven way.
