Possibly a stupid question, but I thought the Chameleon had bolt-in dropouts..?
Is one of them incorrectly positioned, or simply the wrong size?
I would take one out and fit it behind the other to check if it lines up. Alternatively, measure with a string from the rear axle centre to the centre of the BB spindle each side to make sure the back of the bike is straight.
Drop outs are in square...I've tried two other rear wheels and they line up fine, so the issue is definitely with this wheel. I can straighten it out by sliding the drive side drop out back, but it's not right and will just annoy me!
Magsy I'll take some pics of the spacers on the hub in a bit.
