  • Perfect fit
Color: BLACK
Perfect fit on Shimano disc brake internal tooth lock ring nut (21.7mm ID, 12 teeth). Note that if your hub protrudes through the lock nut, and the OD diameter of the hub is greater than the ID of the tool, you may not be able to fit this tool over the hub and into the nut. In that case you will need a nut with external teeth. ... show more

  • Solid tool
Color: BLACK
I bought it to replace my cassette on a pretty old Trek 4500. I worked as described, being compatible with an old SRAM (9-speed) and the new Shimano HG400 (9-speed).

  • I actually purchased this tool to use to remove the spacers from my Yari fork.
Color: BLACK
The tool is dual purpose. I have a very old cassette removal tool that has the pin on the insertion side; that tool can't be used to remove the top of the air chamber on the Yari (and presumably other Rockshox forks), so I purchased this one which has no pin and it worked just fine.

  • Worked Great
Color: BLACK
I used it to remove my Shimano Hyperglide 7 speed cassette from a 1993 Cannondale H400 rear wheel. The tool requires a 1" socket or an open end wrench. Also, I didn't have a chain whip tool so I decided to use my 1500 in lb / 125 ft lb. max torque impact driver. It couldn't crack it lose. I guess it was on too long so I went to my 230 ft lb. impact wrench and it did the job and cracked it lose with ease. If you have a impact wrench, use it. It will make life easier. But when you put it back on, do it by hand and Don't use the impact wrench. I think if I did have a chain whip, it probably would have been a struggle to turn the tool. Use an impact wrench if you can. ... show more

  • Works as advertised
Color: BLACK
It works well at loosening Shimano lock rings.

  • 105 cassette tool
Color: BLACK
Worked perfectly, needed it to remove and reinstall my Shimano 105 cassette. Remember, you'll need a chain wrench to hold the gears to remove it.

  • What’s better than the FR-5
Color: BLACK
The FR-5.2 of course. Added this to my toolkit since my over 20 year old FR-5 isn’t deep enough to install brake rotors with phat wheel spacers. This thin has the depth to get the job done. Park Tool durability and precision. Can also easily knock out an attacker if thrown with the correct Nm of force. ... show more

  • Marzocchi fork? This is the tool you need.
Color: BLACK
If you are like me and wondering for the life of you what tool fits the Marzocchi bomber fork this is the tool that fits perfectly. If you need to change the oil on your fork the left side is a normal hex cap but on the right side under the adjuster is the bolt that requires this tool to remove. Makes changing the oil a breeze now. ... show more
