Works with SRAM
I use this to get the battery cartridge out of my SRAM Rival Crank Spindle based Power Meter. Fits perfectly and works great. A very well made tool.

Perfect for servicing Single Speed Freewheels, especially Shimano
As you can probably tell from my photos, I'm servicing a Shimano Single Speed freewheel, specifically an MX30. This tool is absolutely crucial to be able to get the cover off the freewheel. There're also other uses for this tool such as adjusting older Shimano cranks, Campy cranks, and some cones. Regardless, this is a very handy tool to have in your box and for its price point, it pays for itself in short order. In sum, this is a very well made tool that's worth having! * I realize some of your may be coming to this review because you've decided to take apart Shimano Single Speed Freewheels. Many have said they're not serviceable, but that's patently false. But why service a Shimano Single Speed Freewheel? The simple answer is that while they're very well made, they're not sealed like White Industries Freewheels and over time, they will start to sound a little crunchy and refuse to be silent. So, if you want a near silent single speed freewheel, you either need to drop $80-$110 on a White Industries Freewheel, or you buy a Shimano Freewheel -if you have common sense, you do this because in the freewheel world, you either go big with White Industries, or you go budget quality with Shimano, you don't buy anything else- and you eventually take it apart and grease it. Here's how: *If you still have questions after reading my directions, see this link: https://dirtragmag.com/how-to-rebuild-your-singlespeed-freewheel/ 1. You'll need the above tool, a degreaser such as WD40 or simple gasoline, and for grease, just get some lithium white grease. You can go with several options for grease but lithium white grease holds up well to heat, is thin enough not to gunk up, but thick enough to silence your freewheel and coat all internals. You can get a decent lithium white grease for about $4-$5. 2. You can go one of three ways, next. Either service the freewheel before you ever install it, service it while it's actually installed, or take it off and service. This is personally up to you, but I've always service my Shimano freewheels right away and then once every 3 months because the bike I use them on, is a beater rain/snow bike so it sees horrible weather regularly. 3. If you service the freewheel before installing, just simply take the cover off the freewheel with this tool, turning clockwise, and then just hit it with a nice layer of grease. Then simply reinstall the cover. That's it. You'll have some grease leak out of the freewheel when you put the cap on but that's not a big deal, just rub off the access then turn the freewheel several times to work the grease in. If you want to service the freewheel after it's installed, just take the rear wheel off and take the cover off just like before. Now, you can run a degreaser through the internals if you've got light gunk build up or if it looks fairly clean just do like the first situation above and then put the cover back on. If you want to remove your freewheel after it's been installed and do a complete rebuild, you're going to also need a single speed freewheel removal tool, but those are very cheap. In that situation, remove the freewheel with that tool, then carefully remove the cover like the other situations. From there, have a decent sized plastic bowl filled halfway with either gas or degreaser of your choice, carefully remove all internal bearings and place in the bowl, remove the pawl system and place in the bowl, and the cover and shell. Let everything sit for about an hour then clean off. From there, reinstall the first set of bearings(when you do this there are bearings under the pawls and above) after placing a small layer of grease inside the shell, then replace the pawls, then another layer of grease and finally the rest of the bearings. Then replace the cover, tighten counterclockwise, and lastly, reinstall the freewheel on the wheel by turning clockwise with your hand(the chain and cranks turning a few times will tighten it the rest of the way. Cheers!

This is a PARK TOOL...
You just have to make sure it's the right size for you, quality is outstanding, Park Tool has been manufacturing tools forever and every bike shop is equiped with them, these are true professional tools, made to be used everyday for dozens of years, and I'm a witness as I work at a bike shop, this one looks just as the one we have there since the 90s. It can go way narrower and way wider, will work for bigger holes. Hope this was useful to you!

Does the Job
Needed a 2.3 mm pin wrench for a onetime use. This item fit the bill and it was reasonably priced. Good deal all around.

Strumento ottimo e robusto. Non fate esperimenti con strumenti low cost che poi non durano

Utilisée pour visser/dévisser une cuvette de jeu de pédalier des années 1970. Fiable et robuste, parfait pour moi

Jest wszystko ok.

A good tool I used for a 7 speed screw on freewheel. The pins are smaller than the green tool which fit the cap. You have to whack the pin holes with something pointy to open and tighten this particular part if you want to service it.

The tool is well made and functions as expected.
