    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.

    judt does what it says on the tin

    good for the price

    9ti rychlostní řetěz

    Je to řetěz a zatím se na kole pěkně řetězí. Všech 9 rychlostí zvládá bravurně. Snad mu to dlouho vydrží a nebudu muset kupovat další.

    icon-circle-checkmark verified purchase

    Prodavač mi pomohl s výběrem správného řetezu, nevěděl jsem, kolik mám koleček :-) Ale super byl servisman, povolil mi šlapátka, upravil řetěz. Servisovat chci jen u vás.

    Gute Allzweckkette

    Meine MTB Kette war durchgerostet, nachdem ich damit am Meer durch Salzwasser gefahren bin. Diese hier passt perfekt zu den Shimano MTB Komponenten und läuft sehr flüssig.

    Mtb Kette

    Sehr gut.
