The Park tools equivalent to the Hozan tool: HC-5 Double-ended Lockring Spanner >>> 3 prong end = Max lockring diameter 46mm >>> single prong end = not specified HC-17 Fixed Gear Lockring Wrench >>> for 41-44mm diameter lockrings Since my bikes have BB lockrings which range in diameter from 44 to 46mm (measured by a digital caliper), I will go with the HC-5. Cheers, Bruce Hi Alex,

Did a little more research and found my own answers (funny how that works). The Park tools equivalent to the Hozan tool:

HC-5 Double-ended Lockring Spanner
>>> 3 prong end = Max lockring diameter 46mm
>>> single prong end = not specified

HC-17 Fixed Gear Lockring Wrench
>>> for 41-44mm diameter lockrings

Since my bikes have BB lockrings which range in diameter from 44 to 46mm (measured by a digital caliper), I will go with the HC-5.

Thanks for all the hard work you put in to the videos to make your explanations so simple and clear. It's quite a skill. In your video, you use a Hozan C-205 Lockring tool. Is there an equivalent Park tool? The reason I ask is that, the Hozan tool, which admittedly appears to be a very high quality forged tool, is almost twice as expensive as the Park HC-5 and HC-17 (which appear to be of inferior stamped metal construction). But given that I'm far from a professional bike mechanic, I'm wondering if you knew which of the less expensive Park tools would fit bottom bracket lockrings with square-taper cranks (like the one you worked on in the video). If it helps, I ride / work on late 80's to early 90's steel-frame road bikes such as a Schwinn Paramount or Traveler. HC-5 Double-ended Lockring Spanner HC-17 Fixed Gear Lockring Wrench Other? Thanks, Bruce Hi Alex,

Sheldon Brown has posted an excellent page full of information on them here: http://www.sheldonbrown.com/bbsize.html Hope that helps! Hi George,

All the ones I've seen so far don't even look like that one, it has a rectangular shape, wrap around, but open on one side. I also need a Hooked Lockring wrench like in the video for my toolbox.

If you need a pin spanner for your adjustment and don't have one you can use the points of a needle nose pliers inserted into the pin holes.

You'll have to get a new bottom bracket that matches the thread size and spindle length of your old one. It can be tricky so I recommend taking your old one to a bike shop to size up a new one. Keep in mind the Truvativ bottom bracket uses a special splined crankset. Sheldon Brown has a great database sizing page that may help: http://www.sheldonbrown.com/bbsize.html It may work.

Some says that's an old type. Can I replace it with a new one: Truvativ Powerspline? Will it fit? I have the same type of bottom bracket. Some says that’s an old type.
