the wheels and spokes may be different sizes, but does anyone know if the hubs and axles are the same, how about rotors and bearings and misc. I see a lot of used kx60 and kx80 wheel sets for sale at good prices but the kx65 prices are crazy high. I got an extra set of brand new rims in a lot I purchased and really only need the hubs and spokes to put together a nice spare set for the races. Are all those mini hubs the same or different? I would just call my local Kawi place but I'm offshore in the middle of the ocean on satelite internet trying to get something ready for race season.
