Identify 6-speed freewheel?

Posted on
  • Can anyone tell me what this freewheel is please?

    It was fitted to a Shimano wheel, which was on a Motobecane tandem with a TA groupset.

  • It looks like you can remove it by unscrewing the small cog (with 2 chain whips)

    So like the left one here:

  • So you think this is a Uniglide/Hyperglide freewheel - does that mean the cogs are too?

  • I think the suggestion is that it might be a cassette and not a freewheel as those might be the freehub splines visible at the end?

  • Just uniglide cassette I think, since there isn't a wide spline. The first 5 clogs slide on, the 6th screws on to secure them. You'll need two chainwhips to take the cogs off.

  • Awesome - thank you!

    I just need to find one now. Any idea what NH or HN stamped on the outer cog could be?

  • Can confirm that’s a Uniglide cassette. All the splines are the same width so you’ll need another Uniglide cassette for a straight swap.

    If you get stuck, I have an unused freehub body for sells which will take both types of Shimano cassette and will be a straight swap with that one. It has both the external and internal lock threads and the narrow spline for the newer Hyperglide cassettes. Pm me if interested.

  • Hi
    Just surfing around looking for old threaded freewheels, saw this stuff about Uniglide. You might like to know that are selling some uniglide stuff, they seem to br specializing in NOS early MTB stuff, loads of great stuff in their catalogue.
