The Lithium wheels are brand new from Root Industries. Root is known for making quality wheels at an affordable price, and the Lithiums are no exception! The Lithiums are 30mm wide, which will provide a larger balance point for manuals, and going backwards (fakies). It will also give your deck more clearance on the left and right side. This allows riders to carve a little sharper in bowls, and get away with sketchier fakies since your deck won't scrape on the floor as easy with the extra clearance. Wider wheels don't come without costs though, they are a newer size in the industry, so make sure your fork and deck can fit them! These wheels are also sold in pairs.
