Are my chainrings worn?

[d3v]

Hi all, I'm in the process of replacing my drive train and need to know if I my chainring/s look worn and should be replaced?

[nfmisso]

They don't look too bad. Is the chain jumping on the front rings?

Ditto to what Nigel said. Bad rings look like a stretched out U with the points sharp like sharks teeth.

Nope no jumping, everything actually works perfectly well, however my rear derailleur is a little bent and the chain is stretching so I intend to replace these two components along with the rear cassette but now I know the chainrings are ok that's good news - thanks guys!

If your cassette looks the same as your chainrings, maybe you're not in real need to change it!
