Does anyone know if the J Concepts Rulux3332 SC10 12mm hex wheels - 2.2" x 3.0" will fit on my 12mm conversion or do i "have" to buy their J concepts conversion? I ask because I just bought a roller with the hex conversion with the bearings inside the knuckles. The hexes are plastic with the lips so im pretty sure they are AEs. I want to keep the original offset. All help is appreciated I need to order my wheels so I can race next weekend.
