samquam on July 29, 2025 10:53 pm That looks like it might be a Shimano Uniglide cassette/freehub If that is the case, the last cog is the lockring, so you just need two chain whips to get it off. I believe it loosens the same direction as a standard cassette lockring.

jeffbell on July 29, 2025 10:58 pm It’s probably the splined type, but there is not enough light to see. I would remove the cogs to really clean them, then take off the locknut and the spacer under it to count the splines.

I agree with samquam.
