Chain ring wear

[grellboy]

Looking to replacing my cx chainset as pretty much worn out. Hard to find in the configuration I need - 46/36 - but found this on eBay. It's second hand obviously but just wondered what the opinions of others on the amount of wear on the teeth: don't need to last for ever but nor do I wish to replace it again by Christmas. Pics below for clarification.

No expert, but the inside ring looks OK. The outside however looks like it doesn't have long to go

Can you not just change the rings on your chainset.

Specialities-TA make every size and shape of chainring.

There's not much wear on either rings. Shimano teeth are like that to aid gear shifting. It does confuse a lot of people. If the rings were worn then the teeth look more shark tooth like.

Why is there Shimano teeth on a FSA crankset

Oh right, didn't see that.
But I would say the same about the teeth on that one.

Did think about it but am a bit of a novice tbh and thought replacing the whole might be easier. Will have a look though.

Thanks, will check them out.

I think the FSA have even more short teeth to aid shifting, mine did anyway and they are a lot harder to judge for wear as they looked a bit worn from new compared to Shimano rings.

looks good to me

Looks fine to me but I'd certainly cost up replacement rings.

However if you only plan to keep the bike a few months that crankset would be ideal.

To help see it another way, this is what the teeth look like on my current big ring, which is also FSA. Virtually unrideable due to slippage.

Those are worn. I test mine by taking off the ring and throwing it at a brick wall. If it:

1. Bounces off. Refit and don't worry about it.
2. Sticks into wall for a second or two, then falls out. Refit but start thinking about replacement.
3. Cleaves wall in two. Sell it to a ninja and replace entire system.

Be warned when removing chainrings that the worn teeth can be razor sharp and if your allen key slips you will loose some flesh. Always rotate so if you slip, your finger go in a safe direction. Long handled allen keys are safer than the L shaped ones.
