Never a problem

Have been using these chains for ages and I’ve no reason to change to anything else, I’m not an expert cyclist

Not for regular riding

This chain should not be used if you intend to ride regularly. I have had this chain on my mountain bike for 3 months and its worn out. I've probably covered 200 miles and it's worn out. I have tried 2 of these chains now and they were both poor in terms of wearing out quickly

I'm sorry to read that the chain has worn out so soon. It is very strange that it has. I can assume that you changed your cassette at the same time as fitting a new chain on a worn cassette can lead to premature wear. If the cassette is not worn out and you are not happy with the chain, please feel free to return it to store with your receipt for a refund or an exchange where our workshop team will measure the wear for you and provide any advice if necessary.

Looking for a new Bike chain? then try the B'TWIN

I have been using a B'TWIN 9 speed Bike chain on my touring bikes for over three years now and find I get over 4000 miles per chain which is about what I got with chains costing nearly twice as much.

Good price and quality

I haven't done many miles yet with this new chain but it fits the bike perfectly and I've got that new bike feel again after fitting it with a new cassette. The quick link is simple to use and the bike is sifting gears very quickly and efficiently. I have got the power back in my bike again! Hope to review again in 6 months

Good value KMC made chain

Needed a new 9 speed chain in a hurry and picked this up at Decathlon in Southampton. Was pleased to find that the chain in the box is actually a decent quality KMC Z narrow. Probably worth mentioning this fact in the product description. Very easy to fit with the quick link which is supplied with the chain.
