At road.cc every product is thoroughly tested for as long as it takes to get a proper insight into how well it works. Our reviewers are experienced cyclists that we trust to be objective. While we strive to ensure that opinions expressed are backed up by facts, reviews are by their nature an informed opinion, not a definitive verdict. We don't intentionally try to break anything (except locks) but we do try to look for weak points in any design. The overall score is not just an average of the other scores: it reflects both a product's function and value – with value determined by how a product compares with items of similar spec, quality, and price.
What the road.cc scores meanGood scores are more common than bad, because fortunately good products are more common than bad.

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.
Verdict
The simplest and most effective chainwhip i've ever used

Thanks markymark! I also would be interested to know how easy it is to remove a lock ring that has been tightened to correct torque - either side of 40 Nm. I use a -big- torque wrench to get that much torque.
It's a perfectly reasonable question.
Shimano lockrings are 40Nm. That's A LOT in anyone's book, particularly on a short lever.
If the lockring has been in place for years, corroded with British salt, chain lube and christ knows what else, you may need a lot more than 40Nm to remove it - also assuming the monkey who installed it didn't use a 1/2" drive cheat bar.
So what does the Pedro's Chain Whip give you for an extra £40? a cast-iron ***guarantee*** that it's not coming off that cog, no matter what amount of welly you put into it. There's a reason the Park lockring tool is a 1" drive, and they state you MUST secure it in place using the skewer.
If you are the only person working on your bike, and you keep the lockring / cogset free of corrosive kack / break it apart every few months or so if you are riding lots in the winter, sure the B'twin one will do you.
If you have need to cope with stupid-tight / corroded stuff and don't want to risk an injury or stripped/broken bits, then maybe the Pedro's is the way to go.
Anything designed by Lennard Zinn gets my vote.
@ZachE1: thanks for the link, I bought one from there.
The tool is larger that I expected, so a lot more leverage and hopefully a lot less swearing than my loose chain whips.
Use this one in the workshop.... brilliant tool...better than the Park Tool one we have..... as for comments "siezed" crudded up cassettes...... have removed them with this tool and a 450mm breaker bar (yes we have one for this purpose and also for BB's which are tight too)
Great tool and much better than hooking chain onto sprockets...
Interested to hear if anyone has any long term reviews of this & if it's lasted OK.
As a casual home mechanic don't want to spend a fortune but also don't want to fall victim to "Buy cheap buy twice".
Had mine just under 2 years. In that time it's been used (by me) to remove 8 cassettes, by passing friends twice (they now own their own tools). Still working, showing no signs of deterioration and most importantly, no knuckles grated off.
