Quality unit

Could be better

Quite fussy on what works on it, good when it does. Maybe I expect better of decathlon.

Beautiful tool

I originally bought a cheap “chain breaker” off the internet but it wasn’t well engineered and completely seized up on its second use - I had to cut the push pin with a hacksaw to get my chain out. This tool is fabulous. Everything is perfectly aligned and the chain pins pop out with such little effort. Highly recommended.

Simple solid value for money

I bought this because the far more expensive topeak one I have is rubbish. This tool on the other hand is excellent , it works perfectly and feels solid, making short work of chain link pins and is half the cost of sone more expensive cgsin tools.

Excellent Value for Money

Needed to replace the chain on my bike and this little tool makes the job very quick and simple.

The metal pin got bent when trying to break the chain. Fair enough it wasn't 100% aligned but I was expecting more from this. Cheap quality

Does what it's meant to do - with no fuss!

I have absolutely no idea why some people are saying this breaks after first use... I purchased this alongside the B'TWIN branded KMC X10-XL 10 speed, and cut through it like butter, with no fuss whatsoever! Excellent.

Faulty Pin, Had to Return

I wanted this chain tool as a sturdier option than the Btwin 500 chain tool I already have. It looks robust, yet after a couple of uses the pin bent and the tool was not longer fit for purpose. On that basis, I have to give this item a one-star review, which disappoints me as I'm usually very happy with Decathlon products. I eventually returned the damaged tool to Btwin and due to some confusion received a second Btwin 500 instead of the 900 I bought. I can't be bothered to return the duplicate as I've spent enough money, time and effort on an item costing less than £10.

I'm sorry to read that the chain tool was faulty but also that you received the incorrect replacement. I have arranged for a new 900 model to be sent to you FOC.

Makes the job easy

Feels robust, and well made. Handle gives good leverage

Looks good but not great quality metal

The pin bent on it after the second link! It looks good feels good but not of the highest quality

Thank you for your feedback on this chain tool. I will forward it on to the product manager at b'Twin.
Please return it to us for an exchange or a refund.

falls to bits first use

Hello Chris,

If you could feed back some more information as to what has happened to your bike tool that would be fantastic so I can pass this on to the product manager. In the mean time, you are more than welcome to return for an exchange or refund.

Best I've tried

Had tools like this for years but some last a few times then break or the pins bend but this one looks like it will last a long time might even be strong enough to break my motorcycle chain

Worthless tool broken in less than one week

It got broken on first use. I needed to remove a couple of chains and put them back and I just was able to do one and it was broken. I couldn't believe as I wasn't expecting a life tool, but at least something useful for a while. I got it last week and now I am stuck and withouth bicyle and need to look another way to put chain. I can't recomend this product.
