Tom Stringer My first cassette change ever was just done in seconds with this handy tool.
Mr Lonsdaleived Good product. Easy to use.
Keith Good cassette wrench, much easier to use than the loose lockring bolt that i use for my Shimano set up. This has a more positive operation (obvious really!)
DM Really happy with this. Worked really well. Would have no hesitation in recommending it to others.
Rob Stone Purchased to replace my old tool and this works great as it is attached to a handle gives better leverage to unlock and tighten. Good quality and fit.
Mr Buckingham Does the job and comfortable to use.
James Works well, good with built in handle for ease of use
Dori Well designed, does the job, good value.
Mr Otero Gutiérrez Works perfect with my shimano cassette!
John A lot easier to use than a separate nut that requires a spanner. Worth the little extra cash.
PHIL I haven't used he tool yet but I expect it will perform flawlessly based on its construction. It is exactly what I was looking for and matched the pictures in the online catalog. The advantage of this too is that you don't need to have a socket and breaker bar to use it.
Mr TAPSELL Very well made tool and good value for money
Can Teker Cheap but sturdy. Does the job.
Stuart J Can`t really fault this. cheap and works flawlessly. Never owned any competing product but can`t see how it could be better.
Mr harrop-Peel Easier than faffing with the socket type tool, handles are the future!
Mr Nelson Great product, well packaged and well made
Kazee Has a nice weighty feel to it. Solid piece for the collection.
Mr Fisher This tool does the job just fine and has a good handle-cheaper than some so recommended.
Mr Shackleton Bargain tool. So much better than faffing about with a separate lock ring remover and spanner. Great fit, cassette on and off in no time at all. Should have bought one years ago! Great price and spot on delivery from Merlin.
Mr Fish Works perfectly. Much easier than one that needs a spanner. One twist and it's off - no need to fiddle with spanners falling off.
Jonathan S So much easier to use rather than a cassette tool that needs a spanner, they often slip and cause many headaches. Would highly reccomend
