I have a pair of 40 hole Maxicar hubs with Mavic Module 4 rims, tandem gage spokes, and Sachs freewheel. THE HUBS ARE IN NICE SHAPE BUT THE BACK WHEEL NEED SOME SPOKES ON THE NON DRIVE SIDE. I was going to sell the hubs but I can't get the freewheel off it is tight. $350 a pair plus shipping. Brian Blum in Berkeley 510 331-4773
