What kind of freehub is this?
 

I've got an old Dura Ace Rear hub that has gold sticker around the slightly fatter part of the hub near the freewheel. I'd say the hub is anywhere from an 80's to 90's model. It currently has a six speed cluster with with index cogs 13-28 with camphered teeth. It appears to have splines where the cogs go on like a modern hub. There are no splines on the inside of the freewheel for a freewheel remover tool. Sorry if I come across ignorant. But the only hubs I've worked with are screw on cassettes. There are three small bolts screwed into the biggest cog that seem to act as a spacer. Any help here would be appreciated.

Thanks

Cat,
Hmmm. My late 80's vintage 105 6-speed freewheel takes the standard Park FR-1 splined freewheel remover. One would think that all the 6-speeds would use the same tool. Some older Shimano freewheels may have a plastic dustcap that must be removed to expose the two lugs/notches for the removal tool which would be a Shimano TL-FW10. But I would have thought those would all be 5-speed.

Maybe one of the gurus can solve the puzzle.

Hard to say with out a picture.

Chances are it is simply a freehub. Not cassette.

Take to any knowledgeable shop ad they will be able to take the freewheel off. Very simple process and the tool itself is very inexpensive.

Early shimano freehubs used the smallest cog as a threaded lock-ring, so no splines are visible. You need a chain whip to remove it.
You can replace the freehub body with a more modern version.

Thanks guys. You're right! A chain whip removed the smallest cog which held the whole thing together. It's an old Uniglide splined freewheel. I've only messed with screw-on freewheels. I thought splined freewheels were a new thing. I'm learning lots of good stuff every day.

Excellent!
