Source for Shimano 6 speed cassette?

[Billx]

I own an 89 Stump Jumper mountain bike with Shimano DX 6-speed indexed shifting. Looking to replace
the 6-speed cassette. Anyone know where I can get a replacement compatible with the DX shifter?

Sure it's a cassette Freehub? 6-speed Freehubs are very uncommon, the cassette system didn't really
catch on 'til the move to 7-speed.

See: http://sheldonbrown.com/free-k7.html to figure out the answer.

If it's a freewheel, we've got a good selection, see:
http://sheldonbrown.com/harris/freewheels.html#6

If it's a cassette, you're unlikely to find a 6 speed replacement. You can replace the Freehub body
with a 7-speed one. You'll need new shifters too for the 7-speed indexing (and, of course a new
chain) but everything else will be compatible.

It's definitely a 6 speed freehub. Last time I replace the cassette I had to get a loose cluster of
cogs from the now defunct Third Hand, Left Screw. For some reason Performance had a 6 speed cassette
about four months ago in their catalog but have since discontinued.

BillX: if its a 6-speed cassette then its Shimano Uniglide. This means you can flip the cogs around
to get double the life.

Or, take a modern cassette with the gearing you want, (7, 8 9 speed, whatever) and break it apart.
Some grinding may be required to allow you to pull out the 3 rivets. Then, replace the spacers in
the new cassette with your 3.8mm 6-speed spacers.

Nashbar is selling some 6s ATB cassettes for $12.95.

Unfortunately it looks like it has a lockring and may be Hyperglide splined. If true then you'd need
to reuse your threaded small cog and grind the fat hyperglide splines off the inside of the cluster.

Hyperglide was never available in 6-speed cassette (freewheel, maybe- Sheldon?). It was introduced
as 7-speed equipment, IIRC.

OP: Loose Screws is apparently still around and lists 6-speed cassettes:

There were never any old 1980's 6-speed cassettes with a lockring either, but this one from Nashbar
has one. I would not be surprised to find HG splines on it either - the cogs are obviously ramped
like Shimano HG. I have no idea who made the hub to go with it, unless people are just supposed to
stick it on a 7s cassette body with a spacer.

6 speed Hyperglide cassettes were (and perhaps still are) produced. I have an 11-24 one which I got
from St. John Street Cycles in Bridgwater, England. They still offer this cassette at
(http://www.sjscycles.com) for 16.99 GBP (about $25 US). Whether they were offered in other cog
combinations I don't know.

As another poster has pointed out you can just turn Uniglide cogs over and the unused side of the
teeth gives you the equivalent of a new cog. This works for every cog except for the threaded first
one. Even for this first one you have some alternatives:

1. A 7 speed cog will work on a 6 speed cluster even with indexing since the derailleur is stopped
by the limit screw. Thus if you can find only a 7 speed first cog you're still OK.

2. If your outer cog is a 13 you can use turn it over to use the unused side of the teeth by
getting an extra cog spacer (either 6 speed or 7 speed will do) and put it under the (turned
over) outer cog to replace the built-in spacer which will now be on the wrong side. I don't know
whether this will work with a 12 tooth outer cog or not.

I've got a HG freewheel 6 right here. Worn out a lot, though, and the sprockets even move backwards
and forwards on the splines a bit.

3rd/hand loose screws didn't come back all of the way. All they do now is sell their left over
inventory, web only, no phone calls. They do not have much in the way left of interest.

Shimano europe still lists a HG 30 6 speed cassette in the pricelist (AF, 11-24T)

Possibly you could use a more regularly available 7 speed cluster as source for new cogs, while
keeping your old spacers. This might fail for the smallest cog if, as seems likely, it's UniGlide
and that one is screwed on. (plus the smaller cogs will have integrated spacers, rather than
separate ones. But still, for replacement of the bigger sprockets it might be an option.

I've just bought a 1989 6-speed Raleigh road bike with SIS. I've had the same issue looking for a replacement cassette. The best link that I've found for old 6-speed Shimano isSt James Street Cycles UK

It's in the UK so you'd have to pay postage on top but if you find what you're looking for...
