28 Tooth Loose Cog

Jeff Starr said:

Hi, does anyone know where I can get a Shimano 9-speed compatible
loose 28t cog. I have googled, I have placed a WTB in
rec.bicycle.marketplace, but so far no luck.

I want to swap out a loose 23 & 25 for 24 & 28. I am planning on
joining a club, where I won't have the option of choosing my own
routes. With one leg, my climbing skills are a bit limited. My DA
triple crankset won't let me swap out the 30t, for a smaller ring.

I really think that 30-28 should do it. I currently run a 14-25
cassette and that is why I need loose cogs. The 21, 19, 18 are on a
carrier, and the 17, 16 are rivetted together. I really like having
the 19, 18, 17, 16, 15, 14. With a lot of cassettes the 18 and 16 are
left out.

If someone privately has one, and would prefer, I'd be willing to
trade a 12-25 HG50 9-speed cassette, that has 550 miles on it, for

IRD makes a loose cog 12-28, 9s cogset. The only source of a loose cog,
AFAIK.

If not that, why not buy a mtb cassette (11- or 12-28, 30, 32 or even 34)?

http://sheldonbrown.com/harris/k7.html#9 Go to the bottom of this page
and read about Loose Sprockets for Shimano. Apparently 7,8,9 cogs are
all about the same width and will work for each other. The loose
spacer is the only thing that changes from 7 to 8 to 9 speed cassettes.

Harris Cyclery says they are out of the ones you want until July 2005.
But if Harris Cyclery had them, then other bike shops will probably
have loose Hyperglide cogs too. Just ask at your local bike shop. Or
ask if they have old worn out 8 and 9 speed cassettes and see if they
can be cannibalized. Its unlikely anyone will wear out the big cogs,
just the most used medium cogs. So cannibalized big cogs from a worn
out cassette at the shop will be like new for you.

As for switching the 23 and 25 for 24 and 28, you could probably just
forget about switching the 23 to 24. Just switch the 25 to a 28. I
run a Campagnolo 9 speed cassette and go from 23 to 28 for the last
shift. The short cage Chorus rear derailleur handles the jump just
fine. And I like having the closer 21-23 ratio in the part of the
gearing where I might use it than a wider 21-24.

Same setup here with Shimano HG70 13-25 9-speed: I replaced the 25 with
a 28 for 8-speed. The five tooth jump from 23 to 28 is less smooth than
the others, but still works nicely and gives me a last resort for some
hills here.
Big cogs can often be taken from old MTB cassettes as they wear slower
than the smaller ones. Many people who ride their bike mostly in town
just use one of the middle cogs only anyway.

Harris also has a 13-28 7s cassette for $30; the loose cogs are about
$10, so the OP could buy this and get some spares.

Forgot about that practical solution. Nashbar has 9 speed cassettes in
11-28 configuration for $19.95 less 10% off code found on edealinfo
website. CR201 I am pretty sure the Nashbar cassettes are loose cogs
and not the spider kind. It does not list the individual cogs for the
Nashbar 11-28 cassette but I would guess 11-13-15-17-19-21-23-25-28.
So the original question asker can get the 25 and 28 in one shot. The
Nashbar cassettes fit Shimano freehub bodies.

Bill, as far as I know, the cogs I want, are mounted to a spider on
the mtb cassettes. If that is not always the case, I might consider a
whole cassette.
I want to keep the rest of my current cassette, as mentioned. I like
the close ratios 21, 19-14.

Hi, I have read the cog info, that you listed. If you go to the sizing
chart: http://sheldonbrown.com/k7.html#spacing
The 8 & 9 are .2 millimeter different, the 7 to 9 is a difference of
..7 millimeter, so you are correct, it shouldn't matter.

I had thought that 21, 24, 28, would be an easier shift, but I like
your idea of just changing the 25 to 28. My old bike has a 6-speed
freewheel that goes from 28 to 24, to 21. The problem with
comparisons, is that bike has a double 39/52, so I can't test 30-28
combo, to see if that will be enough for any of the hills that I
encounter. I can get up them with the 30-25, but it takes a lot out of
me and man am I slow[on the hills].

I know Sheldon sells them, but I also knew that he was out of stock
until July, that is a long time to wait.

To be honest, I haven't tried any of my LBS, as I have had very little
success in the past. But it sure couldn't hurt to make a few calls.
Thanks for the info.

Pardon me for asking, but you have one leg? If so, what's that like?

Practice social graces much?

sram cassette's are just held together with a long bolt. so you can take them
apart. I just mixed a 9 speed MB cassette and a road one. if you wanted a 28" I
could give it to you. I used 30 and 26 and I have a 28 I think.

XT-level and up cassettes are mounted on a spider. LX and below are not.
Look for LX and below, or check out the SRAM PG series of cassettes, easily
obtained, and cheap, too.

Perhaps Phil should suggest to the the original poster that he contact
Three Leg Torso, as it seems they have an extra.

But Two Leg Torso would not be as cool for a name.

Hi Steve, I sent you a private email, with my info.

Thank you,

It turns out that Steve doesn't have a 28t, so I am still looking.
