Chainring wear
I got this Ultegra 6603 chainset second hand for a decent price. I'm a bit concerned though by the wear on the big and middle rings, the middle in particular seems to have developed a definite sharp sort of tooth pattern. Also look on the back, I think you can see where the metal has been worn.
The granny ring seems fine.
It can sometimes be difficult to tell given the quite sophisticated shifting profiling.
What you reckon? OK? Replace the middle ring? Or you reckon I need to replace the bigger one too?

The middle ring looks like it's far enough gone for a new chain to slip on it.
The outer will be OK.0
