B'Twin Chain Whip
10 10

Every now and then someone sends in a thing that's just brilliant and you wonder why you've never had one before, and you can't imagine ever being without it again - the B'Twin chain whip is one of those products.

It's not a chainwhip, in that there's no chain. instead you get a double-sided tool with two holes, and on each set there's a set of three pegs that locate into your small sprocket. It works with 11, 12, 13 and 14 tooth sprockets so there's not any I've ever fitted that it wouldn't deal with. once the pegs are engaged you stick your chain tool through the middle and undo the lockring. because there's no chain it works equally well with any type of cassette from 11-speed all the way down.

Honestly, it's brilliant. I've never had much trouble taking off cassettes with chain whips but they do require a little bit of finesse. This B'Twin tool you just slap on and go. The only thing you need to know is how many teeth your little sprocket has. The handle is plenty long enough to get plenty of leverage even for the wheel with the alloy freehub that you have to do up *really* tight to stop the cassette eating its way through it.

And it's only twelve quid.

My only niggle, and this is really picking hairs, is that it's a pity the 11 – the most common one you'll use – isn't on the hole furthest from the handle to maximise leverage. But I can't really mark it down for that because I've not struggled getting any cassette off. I can't really mark it down for anything.

Clever, and if you follow the decathlon link it's on sale for a tenner.

Can you use it to remove a track sprocket?

I would disagree and say that the most commonly used would be the 12 and 13 not the 11.

This looks like a great addition to the toolbox. Thanks for the heads-up.

Now I just have to wait for Decathlon to come to Switzerland. And 2015 is the year!  1

Dave, I'd agree it's less faff than a chain whip. That's a given.

However I'd have to disagree that it can't be improved. The Pedro's Vise Whip is the gold standard for making 100% sure that stuff don't fly apart under high torque; I'd be interested to hear how much downforce you have to remember to apply to prevent it skipping off - particularly with 10- or 11-speed cogsets where you only have 4.5mm mm of pin engagement.

Also, what's the diameter of the hole? Looks like it wouldn't fit a lockring tool flush with the ring itself - so would a deep-section tool be best to use?

Must confess I've not used this one, and it's only £11 not £50. Which is much more sensible for someone changing their cogset every year or so.

They say a picture is worth a thousand words...you could have saved yourself a few by just putting a picture of the above mentioned chain whip engaged in Cassette undoing...

Only for the niche market of people with a 11-14T cog by the sound of it - probably accounts for the eye-wateringly premium price demanded for it.

Actually arguably more verbal irony than sarcasm as my intention was not to directly inflict pain but rather just take the piss... but we're still only talking about a chainless chain-whip in the end.

Are you over accentuating the W?

If you ride a MTB then 11t is going to be the most commonly found small sprocket.

It's not going to be any use for track sprockets, it's not long enough to give enough leverage for a start before you even get onto the subject of sprocket size, apart from that it's quite clever.

A single speed chain is about a fiver and steel strap of the right length is about the same if you need to make one so I have no complaints about the price of this bit of kit.

or a road bike with shimano sora, tiagra, 105, ultegra or dura ace, or a road bike with sram apex, rival, force or red. possibly not a campag bike. but then, they're not as common

Well if you put the tool in place the cassette remover goes through the hole, then you clamp it in place with the QR?

It's a two hander.

Anything which works better than a crappy chain whip will be welcome; I only made mine less annoying by attaching some excess brake cable to the end of the chain tail so that I can tension the damned tail to slip off less often  102 !

I think I'll try this before I try that Pedro's Chain vise; currently £50.99 at Chain Reaction, ouch!

Is it possible to buy this product in the U.S.A. or to have it shipped to the U.S.A.? www.decathlon.co.uk says they do not ship to the U.S.A.

the pegs have notches and are less peg, more bobbin if that means anything?
got mine today, very nice.
not used yet, it would be a bit sad to just try it for the hell of it!
it has a heft to it that the crimson bolt a.k.a. rainn wilson would approve of!
made in slovakia and i'm sure if it was a park tools item would be in excess of £40?
a bargin for £9-99!
