Chain ware.

[johnc]

So I’ve had my Merida e160 800 for four mouths/1200 miles. And my chain is worn out. I expect Merida use low end chains, I believe it’s a KMC X11-93. Should I be looking at better quality chains or are they much of a muchness.

From reading the above, chains wear out more quickly on an emtb compared to your usual clockwork ride. I only ever got 550-650 miles out of a chain on my clockwork bikes. That was replacing at anywhere between 0.6% - 0.7% length extension. (Usual recco is for replacement at 0.75%, scrap at 1.0%).

I am doing rather better on my Eagle 12-speed XX1 chain (on a clockwork bike). I'm at over 1400 miles with about one third the wear. I believe that is because the chain has been surface hardened during manufacture. I see no reason why it should not do as well on an emtb, provided it had 12-speed gearing.

What do you mean by "worn out"? Have you used a chain measuring tool, or is it skipping badly. If you've left it too long you may have damaged the cassette and/or the ring as well.

Worn out based on measurement.

1200 miles seems to a very good result, unless you have also knackered the cassette and/or the ring.

Just the chain .75

Is there a way to search for a topic?

I keep my chain ware with my silverware.
And always keep my chain wear in check with a chain cheque.*
