Different rear cassettes?

I found a wheel that fits the beater I'm putting together for a mate to use. It's a 27 inch wheel but has aluminium (looks like) rims, and more annoyingly a 5 speed sprocket that looks more like a cassette than the screw on I was expecting. It's splined in the centre the splines go all the way through the cogs, but the spline diameter is too big for my shimano tool to fit in, its about a mm too small for my bottom bracket tool to go in! Anyone know from my rubbish description what this is and where I can get a removal tool? Or am I just being a dunce and it is a screw on of some sort? It doesn't make sense to me, I'm used to 2 or 4 pin screw on, or a regular shimano cassette with a screw in disc at the end!!

Stumped

p1eman, I'm not aware of any 5S cassettes. Can you find a brand name?

A couple of sharp, well-lighted photos is worth a couple of thousand words.

The better description of the problem you give, the more likely you are to receive intelligent answers rather than well-intentioned blind guesses.

Edit ... or more questions.

Shimano made 5 speed Uniglide cassettes back in the early 80s, but for Uniglide, the top cog unthreads to get the rest off and there are no inner splines for a freewheel or lockring tool. It sounds like you have a freewheel and you just need to get the correct freewheel removal tool. Does the freewheel have a manufacturer name on it?

This bit makes no sense to me.

Save us all some trouble and figure out how to get pics off your phone.

Best taken outdoors, preferably on an overcast day or in the shade.

When I get a chance I'll take some pics, but I work shifts so 'at home' and 'daylight' are words that don't often sit so close!!

thanks for reading I wondered if it was just something obvious I hadn't come across before. I'll come back when I can get some pics. It doesn't make sense, thats why I'm stumped!!

Pics would be more than useful.
Even a bike brand might help.
I'm guessing Maillard Heliomatic???

Sheldon Browns pics suggest it might be an atom/regina splined screw on freewheel. I'll see if I can pick up the tool somewhere and let you know!

I'm confused because the in the bit I quoted, you seem to entirely gloss over how 'It's splined in the centre the splines go all the way through the cogs' means an external spline, but both tools you mention are for internal splines.

So, could be Uniglide or Helicomatic or other obscure thing, judging from the kinda logically inconsistent description you gave.

Like this but without the dust cover ring that says the manufacturers name on it!! Looks like it might be expensive to replace!!

Options:

1. Use the 5s freewheel

2. Use another wheel

3. Find someone with the tool

4. Destructive removal! I crush em in a vise.

Come to think of it, if it's in good nick you should probably avoid the destruction; a collector or retrogrouch might give you a bit for it.

So would a 'normal' freewheel fit on once I get this one off? Its taken me so long to find this 27" wheel in decent condition I don't want to look for another. I just want rid, this was a favour for a friend. I'm not really into vintage stuff.

Pretty sure there's only the one thread for these; any multispeed FW should go on. 5/6/7 is just a matter of axle spacing and dishing.

Why do people say "rear cassette" ? It's like asking about the front handlebars, or the side crank.

It's such a common mis-expression there must be some reason why people do it - maybe some analogous terminology for automobiles that doesn't apply to bikes.

"Front fork" bothers me too, but not as much.

How about the plural "forks" and "cranks" for the one fork and one crank? It goes on and on.

Because in talking to loads of new or non cyclists they don't know the difference between 'cassette' 'freewheel' 'sprocket' and 'crankset' or 'chainwheel' so adding the descriptive 'front' or 'rear' nearly always saves having to then say 'the cog at the front/back', and helps also if you have said the wrong thing too! The listener can deduce what you meant simply from addition of 'front/back'.

as great as it would be, not everyone is a cyclist, not all cyclists are geeky about their bikes. Some just 'ride' their bikes. Also it takes time to get used to all the jargon even if you are trying your best. Perhaps if 'we' weren't so snooty about it more people might join the ranks. I've got 5 colleagues on bikes this year already with another about to buy shortly. Have you tried to encourage anyone to enjoy cycling recently, or do you just concentrate on belittling them? Does it really matter what words you use as long as the point gets across? my reason for using front/rear is possibly more from riding motorbikes for many years.

Sorry for the crap post, but thanks Kimmo, regular freewheels are cheap enough, I'll give it a go. Thanks for at least trying to make sense of my confusing noob post

The Regina uses a 20 splined remover:



As for the freewheel and hub it is likely that they are English threaded so a replacement will not be problematic, hubs also came with Italian threading which is close to the English save for a slightly different thread pitch, and French threading which is not compatible but then you would probably be looking at a French freewheel.

...

As for terms...

Your bike has one fork while your cutlery drawer has forks.

Crankset or a "set of cranks" is acceptable since there are two crank arms.
