Tom StringerMy first cassette change ever was just done in seconds with this handy tool.
Mr LonsdaleivedGood product. Easy to use.
KeithGood 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!)
DMReally happy with this. Worked really well. Would have no hesitation in recommending it to others.
Rob StonePurchased 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 BuckinghamDoes the job and comfortable to use.
JamesWorks well, good with built in handle for ease of use
DoriWell designed, does the job, good value.
Mr Otero GutiérrezWorks perfect with my shimano cassette!
JohnA lot easier to use than a separate nut that requires a spanner. Worth the little extra cash.
PHILI 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 TAPSELLVery well made tool and good value for money
Can TekerCheap but sturdy. Does the job.
Stuart JCan`t really fault this. cheap and works flawlessly. Never owned any competing product but can`t see how it could be better.
Mr harrop-PeelEasier than faffing with the socket type tool, handles are the future!
Mr NelsonGreat product, well packaged and well made
KazeeHas a nice weighty feel to it. Solid piece for the collection.
Mr FisherThis tool does the job just fine and has a good handle-cheaper than some so recommended.
Mr ShackletonBargain 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 FishWorks perfectly. Much easier than one that needs a spanner. One twist and it's off - no need to fiddle with spanners falling off.
Jonathan SSo much easier to use rather than a cassette tool that needs a spanner, they often slip and cause many headaches. Would highly reccomend
