Damaged teeth on chainring. Performance implications?

El Diego

I have recently purchased a compact chainset off ebay, which the seller listed as unused and taken off a brand new bike. Two neighbouring chain teeth on the larger ring are damaged (slightly blunted), it is as though the chainset has been dropped and these two teeth bore the brunt.

Is this damage likely to cause performance issues such as chain jumping, inaccurate changes etc?

Suggest you carefully file the burrs off to the same profile as the other teeth and use it.
I'm sure you will not notice any problems as the teeth look unworn

The damaged teeth were conveniently obscured in the advert photograph. Chainset was listed as being "immaculate". I think I'm just going to ask for a refund and buy a new one.

Was it a good price and do you think you could get a better one for the money. If that is all that is wrong it is not a deal breaker. You could always try for a part refund.

A few minutes will see you sorted and make imperceptible difference to performance. Try and negotiate a price reduction with the seller based on an inaccurate description.

Cheers for the advice. It sounds like it's not too big a deal so will try to negotiate a partial refund. Apart from the slight damage to the teeth the rest of the crankset looks brand new and it was a good a price so think I will keep it.

Could be that the original purchacer got a replacement for his new bike because of the damage. What was the reason for replacing the c/S in hte first place. Did he say in the ad.

I had a crash about 3months ago and only last week when cleaning i noticed i had 2 damaged teeth on my chainset. I haven't noticed any difference so far. Selling a whole bike with 2 bent teeth on the chainset might be acceptable but selling a damaged chainset with no mention of damage is out of order.
