I successfully shifted my axle over a bit to use my tubular rim with a 6 speed freewheel instead of a 5 speed, as mentioned in my earlier thread about changing over to tubulars. Slightly wider now, with about a third or a half of the dropout's width of axle showing on both sides and plenty of clearance for the chain.

The axle is in there nice and tight, there is no looseness or wobble when the wheel is mounted. On the stand, when I pedal backwards, there is a very slight wobble to the freewheel. Is that normal? I didn't notice it before. THe freewheel went on with a very light touch, so I know it is not cross threaded.
