Chain whips; those annoying, flappy, dirt-attracting greasy things that you dig out from the bottom of your toolbox every few months for a rare cassette removal. When used correctly they do their job, but can also result in faff and knuckle banging to amateurs.
This one-piece Cassette Wrench from Unior does away with all that, offering a solid solution that even I couldn't mess up. The 35cm long tool is for workshop or toolbox use, fits any 11t or 12 tooth cog on cassette regardless of number of speeds, and costs $43.99.

Well, this could possibly be the shortest 'Performance' conclusion to grace the pages of Pinkbike. The wrench is almost too simple - you put it on an 11t or 12t sprocket using the correct side of the wrench, and well, that's it. It connects easily and there is zero chance of slip like there is with a traditional chain whip. If you don't get it, check out Unior's how-to video here.
The 35cm long tool has a comfortable, rubberized handle and provides all the leverage and grip you could ever need. At 340 grams, it is definitely a workshop tool (and has a hole for hanging on a tool board), but when was the last time you changed a cassette on the trail?
This wrench connects to 11t or 12t sprockets, but there is also a larger version that fits 13t/14t. Pinkbike's Take:
