Do you need to lubricate roller blade wheels?
Rollerblade is a brand of in-line skates, NOT a type of skates. Just so youll know.
The wheels no. but I am guessing you are referring to the bearings?? It typically isn't necessary to lube the bearings, but if you do, make sure you use oil/lube that is specific for skates. WD40 will ruin your bearings.
