Just a thought... although this is almost certainly NOT the case for you Harris... but a chain which is too loose can also strip a tooth or two. It wouldn't strip the whole sprocket though, unless it was one tooth at a time over a long period of time!! The loose chain can strip it by not engaging properly with the teeth, and slipping back and forth in the tooth - I have lost an occasionaly tooth that way.




Probably doesn't help here, but getting the chain tension right is important both ways. How did you get on with your claim?

And for Alan R... the frum on these bikes is a drum&sprocket - I think it is a single casting. Hitchcocks sell a machined drum which can have a sprocket attached to it and 'quick-released' for gearing up or down. The drum&sprocket is a pain, cos the drum will be fine!! But the sprocket is goosed

regarding the drum/sprocket , I bought a sprockets and got a local machine shop to turn down / drill / tap the drum unit to take the sprockets

however 38 t is the std size , you cannot fit any lower ,

"if" you have to pay or you get the old unit back , maybe you should look towards buying a spare spk and having the old unit machined as a spare

the replacement sprockets re made by "talon" and seem to take more punishment

If that happened to me in the UK I would, after discussion with the dealer, be straight off to the trading standards people. There's no way you should accept this as "fair wear and tear", or be expected to pay anything to put it right.
