Bones SPF Standards Skateboarding Wheels

SPF stands for Skate Park Formula. Bones SPF Standards skateboarding wheels, and all the Bones wheels with “SPF” in their names, are all made from a special Bones formula that they have determined works best for riding in skate parks. Most wheels have a hardness rating, but Bones is trying something different with these SPF wheels. Plus, they are supposed to never flatspot!

Getting flatspots while sliding on your skateboard just flat out sucks. Never had one? Flatspotting is where you slide or skid on your wheels, and a little area is worn down in one spot on a wheel. From that point on, your skateboarding makes this thumpy-clacky-vibration that’s like running over endless sidewalk panel cracks. At that point, you either hope they just wear back out evenly (which seems to never happen), or go buy new wheels.

Bones SPF wheels don’t flatspot. At least, that’s the claim – and they worked for me. I tried out the 56mms and the 58mms. In talking to other riders who have ridden Bones SPFs, I found one guy who managed a flatspot – once in two years of riding them. He actually hit something, and that did it for him. But only one person in all I’ve talked to, and once in two years, is pretty good!

The bones SPF formula seems to me to be about the perfect hardness and width for riding in skate parks. Looking through wheels and trying to figure out if you want 100a or 98a can be confusing and frustrating. If you aren’t sure what hardness you want, but plan to ride mostly park, these Bones SPF wheels are about the best idea I’ve seen. I highly recommend them.

That said, if you plan on riding street, park, and anything else you find, and don’t have the money to own two skateboards, these wheels might not be the best choice. However, if you ride mostly park, I would recommend them. If street is your style, check out Bones STFs instead.
