Does anyone know what this is used for...

Can we guess without a picture?

I'm going to say it's the tool that's used to hold the back of the nut on the pivot bolt that passes through the jockey pulley of Cyclone GT rear derailleurs.

Here's a video on how to use it: LINK

I'm going to guess it's a proprietary splined socket for Suntour's clipless pedal system (patent licensed from Crank Brothers).

Sorry - guess I can't link to an email picture. Here you go (I hope)...

What do you think the diameter of those things are? Either way, I'm pretty sure I lost.

Spanner wrench for right side crank bearing race and lock ring?

Well that is not the tool I am inquiring about, but it does answer another question. I have one of those tools and have long wondered what it was for. Thanks.

It is a Suntour cartridge bottom bracket tool... they have a unique spline pattern with squared notches and a unique lockring.

And they are VERY hard to find.

It's the tool for installing SunTour's bottom bracket cartridge:

Without a scale to show size, i thought it looked similar to a Park OBW-3

I have one ove these odd tools that I picked up at garage sale for $20 with an assortment of tools. It works great on 80's suntour and some other BB's from that era. One end seems to work fine with better sugino BB's.

Looks like it might double well opening my bottle-O-beer,

Someone was in need of one of those here recently...

Can someone help me identify these two tools? I know that at least one of them is for the removal of freewheels, but what kind?

Thank you!

So much of your surrounding environment can become a bottle opener.

The freewheel remover probably goes to early Suntour/Maeda freewheels or Cyclo freewheels. I cannot help you with the first tool.

That is the tool I have great need for! The small end is used to adjust the hubs of their sealed bearing models used on mountain and touring bikes. I have two sets of wheels that need work and no tool to do the job with. So far I have done a makeshift job, but the hubs are not adjusted correctly. Trying to find a local shop with that tool is next to impossible as they seem to have disposed of them. Nuts!

The second tool is a very old style universal freewheel remover that works for Suntour, Atom and Regina 2 prong freewheels... the Suntour specific tool for two prong freewheels will not work with the others as the prongs are too wide to fit and Suntour sold some shop tools that tend to be less common but tend to be very well made.

I have been using my Suntour chain whip for decades.

The plus to the Suntour specific tool is that it has an ID that lets you slide it past the cone locknut and remove the freewheel whereas these shallower tools will force you to disassemble the axle assembly.

Based on the appearance of the first tool I would say it is for servicing a freewheel or freehub and that it goes in the vice and holds said freehub/wheel? Pastor Bob may have insight having looked inside most freewheel types.

No, the small end of the TA-230 doesn't fit the XC hubs, only the BB cartridge mounting rings. The tool for the XC hubs is this one:

I am pretty sure that the first tool with all of the splines is used to unscrew a Shimano 3 speed internal unit from its hub shell.
