Chainring "blunt" tooth/teeth

[Bianchisti]

Hi guys,

 

Just want to ask if this is normal on a chainring. If had this on for just over 500kms so almost brand new. If you look closely some of the teeth are rather “blunt” or flat. I’m sure it would have looked like this when it was fitted, though I dint check it specifically. Only just noticed it when the bike came back from a service yesterday. Please help.

totally normal, they are manufactured like that to assist in clean, quick chainring shifts.

Perfectly normal. Look closely at this picture of a new ring and you'll see the same thing:

You can also see it in this picture from the manual:

I have to agree. But don't worry Bianchisti, all is not lost, I'll give you R50 for that useless chainset

Not all teeth are meant to look like this:

This has been quite informative. So you learn something new every day.

I've noticed a bigger problem. I think you may be using the wrong groupset...

Then again. Even on the official website it is advertised with Di2 so it can't be that bad.
