What kind of splines on these Sachs hubs?

These are supposed to be rear coaster hubs. I would like to know if they are compatible with newer cassettes (the ones on these hubs are with 6 sprockets):

Sachs makes a dual drive hub with 3 speed internal and shimano compatible body, but I think these are the older type that use a bigger diameter body and therefore cassette. Not sure though.

Cool hubs, but not very practical. More complicated than needed IMHO.

Those are drum brakes, not coaster brakes.

They appear to require Shimano Uniglide cassettes, which were discontinued in the late '80s.

Thanks Sheldon!

So, I would need to file a spline off a Hyperglade sprocket, in order for it to fit on this body. That's more bother than I like, I must admit. I was planning on using it as a singlespeed coaster hub. I don't mind if it's a drum brake, not at all (I can use normal MTB levers with it, right?), but not being able to fit BMX sprockets onto it is indeed an issue.

Can I transplant a Shimano freehub body on these Sachs hubs?

For the record: I have not bought them yet. The fact they are drum brakes (I should have guessed they are not coasters, even if the picture is poor - my bad for not guessing) makes them more attractive, but the spline situation is discouraging.

It is NOT a "coaster" brake, it's a hand-operated drum brake.

Splined BMX sprockets will fit fine, they aren't Hyperglide.

See: https://sheldonbrown.com/harris/singl...html#sprockets

If it's normal Uniglide, you can use an English/ISO bottom bracket lockring to hold the stack of spacers and BMX sprocket in place.

If you like the drum brake, these are highly appropriate for singlespeed use.

Thanks a bunch. I know it's not a coaster hub - I was just telling what I thought initially. Yes, I love drum as well as rollerbrakes. I'm moving (little by little) all my bikes to rollerbrakes in the rear.

EDIT: and I just compared a BMX sprocket with a Hyperglide sprocket - and hot damn, you're so right, the BMX sprocket does NOT have the one larger spline.

Bummer - those hubs aren't uniglide or hyperglide - the BMX sprocket desn't even engage the splines.

By the way, now that I've bought them (with those sprockets you can see on the pic, so I still can use them, just not with my BMX sprockets) I can see that the model name is "Galaxie". After that there's something that looks like 1-IT, or maybe it's a stylized "1 HT", don't know.
