SATORI's soft wheels, 57mm, 78A. No punctures, and I don't think there's much wear that has changed the size. I washed and polished them for the listing, and I think they're clean. Recommended for those who want a moderately sized soft wheel with speed, but don't want to make their board too heavy. For preference, a thin riser pad (about 1/8 inch) is recommended. If your board has wheel wells, you might be okay without a riser. No returns or exchanges, please.
