Worn out so soon

[Sankey46]

How long should it be before components wear out?
I bought a Kona Jake last Nov and in the last two months have had to replace a front chain ring, chain, rear cassette and now the rear hub has gone today.
I have covered nearly 2500 miles since Jan.
Is this realistic or am I expecting things to last longer?
May need a new one in Nov - god bless the cycle scheme!

In about the same distance I had to replace my chain which ate the rear cassette as I should have changed it sooner and my front chainrings are a bit borderline really I think. I guess it depends on how you look after it and what it has to put up with, when I ride on sand my bike sounds horrible afterwards and needs a thorough chain clean. Dunno about hubs, but chains are pretty much consumables and cheap to replace if you dont let them wear so much they reshape the chainrings and cassette

I'd say you got more than your money's worth out of the chain if you used it in all weathers... Unfortunately leaving a stretched chain on will wear the cassette and chainrings. On my commuter a chain lasts around 1000 miles and I replace the cassette every few chains, for various reasons I've ended up changing chainsets before I've worn a chainring out.

The rear hub sounds iffy to me, my 105 rear hub has probably done 3 or 4 times what yours has and is showing no particular signs of wear; I'd be seeing if I could get that sorted under the warranty - although if its just bearings it should be cheap and not worth the argument.

I am getting the work done by my LBS. £45 so not to bad, one shop insisted I needed a new wheel!!
Would go to Evans who I got bike from, but from previous experience I know their customer service is shocking- but that's another story. I won't darken their door again :-)

The chain would probably have been due a replacement but not the rest. Certainly not chainrings - they should last for ages!

Have done 2500 miles on mine, had the chain measured 2 weeks ago and was told it was 50% worn, but it is cleaned and lubed regulary, also it's campag.

 

[Sittingduck]

If your chain is 50% worn then it's quite likely that when you replace it, it'll skip and you may well need to swap out the cassette also. Try to replace the chain as soon as it hits 75% wear, if poss. I didn't bother myself on one of my bikes and it can become costly, having to replace cassettes, every chain switch!

 

[MattHB]

You left it to late in replacing the chain. If you push a heavy gear that'll destroy it even faster.

My commuting chain lasts about 1000-1500 miles on average before it hits the 0.75 mark (including winters). But yeah leaving a worn chain will wear down your cassette - chain rings are usually a bit tougher though.

My WH-R500 rear hub has done 3000 miles, been re-greased once in that time.

Regarding the 50% & 75% worn figures: What does that actually equate to in distance?

2500 miles in my case.

That's a very short time for a chain to live. I suggest you clean and lube it more often than you currently do. I do my chain every 90 miles or so, it only takes a few minutes.

oops My bad.

What I meant to ask was what did 50&75% equate to in chain stretch distance ie milimetres.

About 1%, or something like .005 inches per link, IIRC.

To the OP, if you've done 2,500 miles on a chain which needed replacing for much of that distance, that could be why you need new cogs too.

 

[Rob500]

Thanks Norm.

I've done 1200 miles this year. I didn't count last year's mileage when I got my bike at first. I've no idea what the previous owner put in or whether it's even the original chain. I've tried to check it via the school ruler method.
The 12" mark is hitting the edge of the rivet rather than the centre line. I've tried to mark the area in this image.
Should I be considering replacing the chain as a priority?
