OJ Wheels is proud announce their latest filmer union with master lensman, Thomas Campbell. Thomas Campbell's new KeyFrames (56mm, 87a) are a solid choice for someone looking to set up a skateboard for all conditions. The 87a soft urethane formula makes KeyFrames the perfect choice for a cruiser / filmer board or set them up on your regular skateboard when you're hitting a rugged spot. Blaze All Terrains.
