What freewheel type is this?

[ElCani]

Hi. Can someone help me identify the tool needed to remove this freewheel/sprocket cluster? Doesn't seem to match anything on Sheldon Brown. The hub is a Shimano 105 FH-1050.

Cheers!

Re: What freewheel type is this.

It's a Shimano Uniglide cassette. The smallest (threaded) sprocket acts as the lockring, while the others slide onto the nine equal splines visible around the bearing dustcap. You need two chain-whips to remove it: one to hold the block from rotating while you unscrew the smallest sprocket with the second.

Ah ha! Many thanks.

Once I get this off, I'd like to replace the freehub body with something that I can fit a wider range cassette to. Anybody know if this will work and if not, which type I need?

Thanks.

not a specialist of freehubs body but the major constraint will be the width available for your body I would say even if you can tweak a bit with the bolt and spacers - I suspect you have a 126mm hub

here Sheldon has done all the hard work for us :idea:
