Super heavy duty hub/axle/bearings, 12 gauge spokes, Weinmann rim, see http://www.staton-inc.com/Details.asp?ProductID=3177 for details. Note that the hub is priced separate from the wheel by them. This wheel was used for only two weeks, it's almost new, cost me a little over $250 after shipping. Can include a used left side freewheel. Shipping at actual cost from 85719.
