This is one of the better single purpose tools I've added to the basic tool kit that I bought a decade or more ago. I always found the chain whip awkward to use. Maybe if I used it more than a couple of times a year I'd be better at it. Regardless, this pliers is incredibly easy to use and you don't have a greasy length of chain flapping around. Highly recommended!
I was able to remove a 18T cog and a 22T cog with these. I bought them because I imagined they would be easier and more secure to use than a chain whip which I had never tried before. They were easy to use but they don't open very wide and it was a struggle to get them to clamp onto the 22T, so I can't really imagine them working well on a 24T or 26T. The product description advertises that they work up to 26 T, which seems to be a bit of a stretch to me.
I hated chain whips for cassette removal with all that extra chain hanging and the rest of chain that was actually used got oily and dirty from the cassette....which was why the cassette needed removal in the first place. Now I have two dirty things. What a mess. These cassette pliers make that a thing of the past. Cassette removal is now a snap. Grab a cog with the pliers and with your cassette lock ring tool your adjustable wrench and twist; it's off. Wipe the pliers with a rag and put them away. Done. My only complaint is that I waited so long to get them.
I replaced my cassette for the first time with these and they worked fine. Obviously I don't have anything to compare them against. It was a bit fussy to figure how to spread the jaws apart, but probably less fussy than a chain whip. Those things look even fussier...
Value? Who knows?? Tools are pretty much always cheaper than paying someone else to do it.
This tool replaces a conventional chain whip. Chain whips aren't hard to use, but these pliers are easier. Where they really shine is when you need 2 chain whips for freewheel disassembly or Suntour cassette removal . Build quality is excellent. My only complaint is that, while you can lock the handles together for easy storage, when applied to a cog, the handles can't be locked in place.
I am not a great mechanic, and in the past have at times struggled with cassette removal using standard chain whips. I purchase the Feedback Cassette Pliers to replace a Performance Spin Doctor chain whip that snapped while I attempted to change a stubborn cassette.
I've only used the Feedback Pliers twice, but it is noticeably more user-friendly and secure than the standard chain whips I have used in the past. Provides a really strong, secure grip. Highly recommended.
