I know this may sound silly Tom, but are you sure you are not pulling
the wheel back to far and thus putting too much tension on the chain.
If the chain is even a tiny bit too tight it can bind the rear wheel,
especially if the sprocket and the chainwheel are not quite round or the
chain alignment is off a bit. Anyway, just a thought.

Yesterday, after fitting a track bike with a rear wheel and tightening
the
locknuts on the dropouts, I noticed that the wheels did not spin
smoothly
and stopped abruptly. I surmised that tightening the locknutsl onto the
frame squeezed or put too much pressure on the cones, forcing it against
the
bearings instead of riding smoothly. I used a different rear with the
same
result. The spacing in the rear drop-outs is about 114 mm, and the
wheels
are approximately the same from locknut to locknut. As it is right now,
the
only way I can get the wheel to spin smoothly is to tighten the locknuts
into a position where, when riding the bike, I would for sure pull the
rear
wheel forward or make it go into the chainstays.
Anyone have experience with such a problem and might know a ready solution? Both wheels have cup and cone bearings.
Thank you.
Cheers.
