Thanks all, I am aware of the differneces between freewheel and freehub configurations including the moment arm differneces due to bearing locations. This is a 6 speed as originally sold. I plan to milk it as far as I can as I am not interested in replacing the hub, cog set, derailuer, and shift controls that are likely to be included. The bearings are fine with marginal cones. Yellow Jersey has replacement axle and cone kit, which I am thinking of going for. I will just need to get a skewer with internal cam. The one I have is an external cam skewer, which is fine for the front but I would prefer better clamping at the rear.
