Btwin, Chain Whip Cassette Remover

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.

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.

Great tool at decent price

Have used on 2 bikes, with both 11 & 12 tooth cassette sprockets. Very easy to fit over a Shimano hex cassette tool and hold the cassette in place while turning the lock ring.

I am very impressed with this tool, its a good strong very well made tool.. Well thought out, right down to slanted hole for hanging up centrally. It is easy to use as there are no moving parts, just like a spanner, once in place it does not slip and combined with a lockring removal tool it is a simple one handed process to use this tool. Good grip in hand and on the job.

I have used this now to change cassettes on both my campag and shimano groupsets. To say that it is simple to use is an understatement, and it makes the whole operation unbelievably simple and effective. I recommend this product most highly.
