Well the wheelset I had on was the stock wheel set, so basiclly the $150 is like cash in my pocket, as they would have just sat in the garage, the retail on the wheelset is $600, my LBS, and best bud gave them to me at cost $400, so in theory it is $250 out of my pocket for a wheel set that retails for $600, but enough of that then. The hubs are Shimano Deore XT hubs, can't remember off hand what kind of spokes were used, but in the end just a killer wheel.
