      Yeah to some extent put a chain on it and try to lift the chain if it moves easily it’s worn. If it skips teeth or the chain falls off it’s time for a new chain ring. A chain ring will often last 3 years of everyday cycling if the bike is cared for 2 if it is not. Something like 20,000 km with a bad drive train and 50,000km plus with a good one.

      I recently replaced my grx 810 chain rings after I had the chain drop a few times on the chain ring after 3 years of use.

      This is absolutely fine, I’m not sure why the other comments are saying to replace. What you need to look out for is the shark tooth like shape.

      If it’s noisy with the new chain, sometimes a new chain will take a bit to bed in with the teeth.

      You don’t need to replace until you feel it skipping or struggling to shift

      Is this new Ultegra or one of those that are under a recall? If latter is the case, you might get new chainrings for free.

      By the looks of the ring i’d say replace. But the safest way to tell is when you notice the chain dropping often and “slipping” while sprinting.

      In some places it looks more worn than in others, e.g. the teeth next to the front dererailleur look fine tbh. But the ones to the right of the image a little more worn. I’d say there’s life left in it for sure, but perhaps get it looked at when you next take the bike in for a service / job at your local shop.

      But it’s nothing to stress about too much imo

      Thanks all for comments. Definitely not finding it hard to shift or noticing any skips under load so sounds like it might be ok for a little while longer.

      It’s definitely worn, but personally I only replace when it skips (unless you’re going on a world tour where replacements might be hard to get by, then, yeah, replace).

      It’s certainly worn, but the teeth aren’t pointy so you’re fine! Keep running it, then plan to replace them, the chain and the cassette at a later date.
