The tool does exactly what it is designed for
Grips 11 tooth cassette fine but you need a longer cassette tool, like the decathlon one, to get a spanner on without fouling the teeth for the other sizes.
Good piece of kit and did exactly what I needed it for.
Easy to fit onto the cassette (mine is an 11 speed) but the lugs on the opposite face get in the way of the spanner preventing you from easily turning your cassette removal tool
Snapped two chain whips from amazon trying to remove a particularly light cassette lockring. This tool is a beast and did the job perfectly
Really impressed with this tool. An ingenious solution to the problem of gripping a cassette - I'm surprised nobody else makes or sells them (as far as I've seen). I've just used it for the first time and it worked a treat. That was on the 12T sprocket of a Shimano 12-25 block.
I did notice however the reviewer who said it didn't fit their Shimano 13T sprocket, so I then tried slotting (the now loose) 13T from my block on the tool - it didn't fit properly and then jammed and I had to force it out. The 12T sprocket fits easily and snugly. So there may be a problem with using it on 13T sprockets.
Simply does not fit on my Shimano 13T sprocket...really it does not - too tight. As an experienced bike maintainer, I am so disappointed with this tool...back to the trusty and traditional chain-whip.
Thank you for posting your review regarding this cassette remover. I have asked the team at b'Twin for a reply as there is no reason why it should not fit correctly. I wonder if there is a fault with your particular item? I know it works (as I have one myself) on 11T and 12T but I have never had cause to try it on a 13T yet.
Please return it to us for a refund or an exchange.

Compared to the old style chain whips this is just so easy to use and can be use of a wide variety of cassettes. A must for every bike tool box
This is a superb tool.
Its not a chain whip - it's far superior.
Extremely robust tool - already used it twice in two weeks to remove cassettes.
Easy to use, keep clean and keep your hands clean when removing the old mucky cassettes.
Great price at Decathlon for such a super tool.
Such a simple idea. Robust and easy to use along with a cassette lockring remover. I am left handed and always find using a standard chain whip i.e. the type with the short length of chain attached , a bit awkward. This tool makes the job easy.
