Replace your chain more often and your chainrings will last *indefinitely*, as will your cassette. Had my chainrings on since 1995.
There is no rule of thumb IMO.
My Raleigh with an Ofmega chainset and Sora cassette had done circa 3 or 4000 miles on all the original equipment.
I changed the chain and left the cassette and chainrings. It still works well, allthough there is some wear evident in the chainrings.
The cassette looks absolutely fine.
In your case MP, if you've done the chain AND cassette, i think i'd do the chainring as well. If its not sitting properly in the teeth, you're just going to shorten the life of the new chain.
I'd only replace chainrings if the chain started slipping. Worn rings won't damage a chain, they are only made from aluminium.
You will get away with chain ring wear much better than rear sprocket wear - unless they look like shark fins then keep them... Just on my 3rd set of chain rings on a 22 year old crank set - training bike !!!!
You need to replace the worn chain ring now, otherwise you will soon wear out the new chain.
I guess it's down to how much you do, or dont want to, spend £15 (ish).
Spend it and you will benefit.(but you may not even notice the difference)
Dont... your chain wont last as long .(but you may not even notice the difference)
There is no clear answer.
Do you want to feel happy and spend £15.
Do you want to feel unhappy, and spend £15.....
The choice is yours.
Rings are aluminium (soft). Chains are steel (hard).
Worn rings won't wear the chain.
When buying chainrings, do search about a bit.....
Ribble are priced well with Stronglight's Dural and Zircal rings for road bikes - dural is 6000 series, zircal 7000 series alloy and better, but a good price and look well finished. The dural ones are fine - been using them on my training bike for years, but not as 'pretty'.
Just got a really good MTB outer ring - 110 BCD from chainreaction - Blackspire 7075 alloy, ramped etc, and just £15....
wouldn't it be better then to have an aluminium chain?
These are steel (and have got a lot of miles on them over the past 9 - 10 years)
and so are these
infact, in 60+ years of cycling I've not used aluminium rings yet .
...or even tight fisted northener.
Aw c'mon . I'm trying - I removed this
and replaced it with these bits
OK it's not really an Ahead set - but it looks like one (that's the Luddite bit dealt with) and it must have cost me all of £16.00 in parts + I fitted a new headset that cost another tenner (that's the tight arse bit sorted) .
