Hello..Recently I bought an early Waterford Paramount on ebay. The rear spacing is 126. I suspect the rear hub is originally a 120 that was overhauled and cheaply spaced out to 126 before the wheels were rebuilt without changing the 5 speed axle because the axle only portrudes about 2 or three threads out of each end of the hubs. I don't know if these were ridden this way or if this was a throw together for the auction (the freewheel was just spun on with no grease and didn"t suit the NR derailleur). The question is; HOW DEEP DOES THE END OF THE AXLE HAVE TO GO INTO THE DROPOUT THE BE SAFE TO RIDE? I know that the QR puts the whole thing in "compression", but if I keep and ride these wheels do I have to order a 6 speed axle and rebuild this hub first?...thanks from Patrick Lay in Chicago
