Cassettes Are Not Eco-Friendly

[James]

I like to bicycle commute. I do it for health and enjoyment first.
Positive "green" effects on the environment are side benefits but it's
not a primary motivation. I support the green concept, I'm just not
hard-core about it. I still own cars.

Cassettes really bug me. Invariably I wear out one, maybe two cogs,
which leads to cassette replacement. It bugs me to throw away a
cassette that still has 8 perfectly good cogs on it.

Instead of cassettes, why can't Shimano and Campy come out with 9- and
10-speed gearsets that have no cassette. Just a set of 10 cogs and
spacers. Just stack 'em up on the hub. That way, when your one or two
favorite cogs wear out, just replace the worn ones and keep the unworn
ones.

Cycling has a great image of being an eco-friendly sport. I think
coming out with fully replaceable cogsets would help improve the image
more.

If you're using 9 speed cassettes and throwing them away with 8 good
cogs on them perhaps you should consider a single-speed next time

Campag cassettes are like that-- the only thing holding the sprockets
together when you buy a new one is a bit of plastic and a rubber band.

You probably can buy Campag sprockets separately.

I'm not sure if the popular image of cycling extends to understanding
the details of how cassettes are put together.

You could always recycle your old cassettes-- after all they're probably
made of steel, which can be melted down.

No it wouldn't.

I just googled your "problem" and can't really find anyone else that
shares the same outrage. It's just a little steel--if it really bugs
you, just drop them off at the local recycling center. Geez.

or change to hub gearing. that would facilitate a full chain guard
then, lower chain wear, and thus even greater eco-friendliness.

indeed. steel has about the highest post-consumer recycling rate out there.

Reasonable-sounding point, but most riders do have their favorite
ratios, and will usually wear out one or two sprockets before the others
have appreciable wear.

That's what they used to do, and some still do. Cheaper Campy cassettes
are available with loose sprockets, and I use them to mix-and-match the
gears I want. But I always wear out the 21 first.

Not all of them. Some higher-end Campy cassettes are riveted, with the
largest several sprockets together on a carrier to save weight.

> You probably can buy Campag sprockets separately.

At a cost. The cost is high enough that replacing a couple sprockets is
no cheaper than replacing the whole thing. And, do recycle.

That has been my experience.

I can and do buy and replace individual sprockets (and spacers).

They'll tell you that the designs of the individual sprockets in each
cassette are optimized for the cassette in which they are installed.
This is true, but the real reason that they don't sell loose sprockets
is profit; it takes precisely as much operational overhead to ship a
$9 single sprocket as a $40 cassette, and they make a *lot* more from
the cassette.

There have been sources from which individual sprockets could be
obtained at times, but the supply has always been spotty...and many of
the new cassettes can't be disassembled to replace a single sprocket
in any event.

Well, both Shimano and Campagnolo actually sell individual sprockets
as spare parts.
Look at their technical documentation, note the spare part number,
order the spare part from any certified Campagnolo or Shimano dealer.
This is how it should work, at least in theory.
Few online dealers sells Shimano or Campagnolo spare parts, and fewer
seems to have individual sprockets. In the EU I only know of www.rose.de
who carries such spare parts.

Well, they list them. Usually you can get Campy. Usually you can't get
Shimano.

Get a tighter cassette and it will be easier to use more cogwheels.
My utility bike now has a seven speed 12-13-14-15-17-19-21
with 50/39 chain wheels.

Dumbass,
This is an Assos towel. It has the following important properties:
"
The towel is about the most massively useful thing an interstellar
hitchhiker can have. Partly it has great practical value - you can wrap
it around you for warmth as you bound across the cold moons of Jaglan
Beta; you can lie on it on the brilliant marble-sanded beaches of
Santraginus V, inhaling the heady sea vapours; you can sleep under it
beneath the stars which shine so redly on the desert world of Kakrafoon;
use it to sail a mini raft down the slow heavy river Moth; wet it for use
in hand-to- hand-combat; wrap it round your head to ward off noxious
fumes or to avoid the gaze of the Ravenous Bugblatter Beast of Traal (a
mindboggingly stupid animal, it assumes that if you can't see it, it
can't see you - daft as a bush, but very ravenous); you can wave your
towel in emergencies as a distress signal, and of course dry yourself off
with it if it still seems to be clean enough.

More importantly, a towel has immense psychological value. For some
reason, if a strag (strag: non-hitch hiker) discovers that a hitch hiker
has his towel with him, he will automatically assume that he is also in
possession of a toothbrush, face flannel, soap, tin of biscuits, flask,
compass, map, ball of string, gnat spray, wet weather gear, space suit
etc., etc. Furthermore, the strag will then happily lend the hitch hiker
any of these or a dozen other items that the hitch hiker might
accidentally have "lost". What the strag will think is that any man who
can hitch the length and breadth of the galaxy, rough it, slum it,
struggle against terrible odds, win through, and still knows where his
towel is is clearly a man to be reckoned with."

I raise you with a $356.40 Gucci towel:
http://www.bluefly.com/pages/products/detail.jsp;jsessionid=IfvipG4qepceXI6mId4TNUoSHgyyrpf821c2ex4MS0TAKwbkeZnl!-2052167204!app4.l3.bluefly.com!7005!8005?PRODUCT%3C%3Eprd_id=2087338697&FOLDER%3C%3Efolder_id=2047121551&N=2047121551+4294967101&Ns=Popularity%7c0%7c%7cProduct%2bCode%7c1&Nu=Product+ID

While this Assos beach towel is overpriced, Assos bibs and winter gear
is top quality. I know several people who says that Assos bibs like
the F.I. 13 or Mille is the best cycling investment they have made.
