How long should a front sprocket last?

[Jon The Bassist]

Okay, so I'm on my third chainwheel in only 6 months of regular use of my NS cruiser. The first chainwheel was used, and the next was almost new.  I know I put a lot of strain on the drivetrain but it doesn't seem long. I suppose I should be grateful that I'm not breaking chains like I was a year ago.

Try a mid skool one all this gay lightweight stuff just isn't bomb proof like stuff was ten years ago.

Are you cleaning the chain (and lightly lubing) and chainwheel regularly Jon?

Some tracks are proper chain killers, dusty surface particularly in warmer weather (Hartlepool  ).

toooo much power dude
mine usually last about a year, if youve stretched the chain it wears out the chainring

[Dark Diggler]

I'd say your chainline may be slightly out

Cheers guys - I did change my chain (just a few weeks ago) when the last chainwheel already had some wear on it and it seems to have got worse quick. Anyway, got a beefy looking Dragonfly Tie 8mm thick one on the way now

ive had my redline 44 one about 25 years still going strong.

check the chain line is perfect as you can get it john
also simon will probably confirm this but if you change a chain you should change the ring?
ive never killed a chainring ever.but im not poiwerhouse like you l;ol

[Jon The Bassist]

Chain line is reasonable, just me being heavy, fair strong in the leg department, and also putting the power down in a completely un-smooth way (stamp!).
I've just got the beefiest chainwheel I've ever used and combined with an almost new chain, so fingers crossed eh!

some are made of real cheap alloy, rub em with ya hand and they bend and oval on the spindle, sounds like its outta line
