Converting 5 speed to 6 speed.

I'm interested in changing my back wheel which is 6 speed and 126 spacing to another which has a 5 speed freewheel and since its 5 speed I assume is 120 spacing.Can I put the 6 speed freewheel and spacers on the 5 speed wheel?Both wheels are 27 inch.My 6 speed wheel has a bad hub.

i confess i don't quite understand your question, but if you want to put a 5-speed 120mm spaced freewheel hub on a bike with 126mm spacing, the axle may be too short. if not, you may need spacers. ... i think...

Why do you want to change the wheel?

Measure the over-locknut-distance (OLD), because it might be 126mm. And if it's 120, you can still use it without modifying the frame. If, for some reason, you just want to run a 5-speed freewheel, you can screw that onto a 126mm hub. Adjust the derailleur and go.

I've done it the other way around, going from 5 to 6 speed, with no modification at all and just a minor adjustment to the hi and low stops on the RD (Schwinn Tourist with friction stem shift).

I would put 3mm of axle spacers on each side in order to keep the 5-speed wheel centered in the 126mm dropouts. (And, of course, adjust the rear derailleur.)

Cog cluster that much narrower the hub can shift to the right a bit on the axle & spacer shifting and redishing the rim a bit to re center it between
the axle ends ..

it can be good .. frame remains 126,axle remain the same.. the hubs location on the axle changed..
