I bought this bike, described as the gears 'running perfect'- when I recieved it I discovered that what I think is chain stretch has caused there to be so much play in the chain that the rear derailleur kicks back and causes the chain to rub over the upper cog on the derailleur- I hope you can see what I mean by the picture.
My question is, is this caused by chain stretch and therefore a sympton of an old, worn out drivetrain?
If this was occuring on your bike, would you describe it as 'running perfectly'?
Im currently involved in a claim against this guy on Ebay, so I'm basically checking that my argument stands up.
I'll be back soon with photos of the corroding crown of the fork (The seller maintains that aluminium cannot corrode)...
