Used Cassette- Bad idea?

I was offered a slightly used (300-500 miles, allegedly) XT cassette to
put on a touring road bike. It shows minimal wear, but I'm wondering if
this is really saving money and if a new chain would wear in as well as
if it was mated with a virgin cassette.

Cassettes can age quickly if your chain is not well lubed or you're all 500
miles were on dusty or sandy trails. If the cassette was used only on paved
roads, it shouldn't be too bad.

The wear to worry about is probably hooking of the most-used cog, which
will cause a new chain to skip under load. An older chain will have no
problem because its stretch accommodates the hooking.

It doesn't hurt the chain, but you won't like it.

The tooth spacing isn't changed by wear.

Of course the spacing is changed or actually deformed, which amounts to the
same thing. That is why you should change your chain before it has stretched
1%. The stretched out chain wears down the cogs so that when you finally put
a new chain on it will not fit properly and start skipping. If you let your
chain get really bad it will eventually wear down the teeth on the
chainrings as well.

To the original poster. I'd never buy a second hand cassette. If I must.
There are tools to measure the cogs to determine how worn it is. A brand new
cassette doesn't cost all that much unless yo go to Dura Ace, XTR and Campa
Record.

WHAT? If you follow this odd reply, then you must change cassettes
every time you change chains. Its a used cassette. A bit too
expensive and unnecessary to me. But then internet bicyclists are odd.

It was on a *road* bike, so I doubt there's any tangible wear.

Put it on with a new chain, if it doesn't skip in any gear, you're good
to go.

Good job. 😉

The tooth spacing depends on the distance from the center of the cog,
not the shape of the tooth.

But the shape of the teeth defines where the chain will (want to) ride and
thus said distance.

You don't even understand what you wrote in your first reply.

Your complete first reply is below.

Now lets consider each piece.

Quoted message said:

Official reply: NO, never a used cassette with a new chain.

If you follow this odd logic, then you must replace the cassette every
single time you replace a chain on a bike. Because the cassette is
used. And your odd official reply says you must use a new cassette
with a new chain. Odd. Why would it matter who the used cassette came
from? Do you think the new chain cares if it was you who put the wear
on the old cassette instead of a stranger? The cassette is used either
way. An odd reply whether its official or unofficial.

Your next sentence.

Quoted message said:

do it after a visual inspection.

So you give a reply and then state the exact opposite. So is the
official reply the reply or is this the reply. Which is false? Which
is true? Do you always answer questions with Yes and No. True and
False. Left and Right. Up and Down. Do you really believe the new
chain cares if the used cassette was cheap, free or expensive? Does
this affect its engagement with the teeth on the used cassette? Do you
think you can really tell the wear on a cassette by visual inspection?

And your last statement.

Quoted message said:

Probably true. Maybe not. A few hundred miles of riding on gravel
roads in the rain is different than a few hundred miles on dry asphalt.

And your last statement.

If you wrote this you supposedly knew you stated dumb things in your
post. Why not just correct the dumb things in your post instead of
write this last sentence? If you work in a place that requires you to
turn in written reports, do you put in a last sentence or paragraph
saying everything you wrote is wrong and unbelieveable?

There should be some concern about wear of the cogs. When
I worked in bike shops sometimes we would have bikes come
back in a week or two with complaints of the chain skipping.
This was caused by the customer shifting onto the smallest
cog and riding in that gear the whole time (and usually the
small-small combination). We would replace the worn cog,
give the customer another shifting tutorial and send them
on their way.

The previous rider certainly could have worn out a cog in a
few hundred miles; especially if (s)he rode exclusively in
one of the smaller cogs.

As one of the previous posters recommended, install the used
cluster on the bike with a new chain. Test it by riding in
each gear to see if it skips. Then if any cogs skip replace
them.
