chain, chain ring

Just curious. The cassette looks pretty durable compared to the
lighter alloy chain rings.

Don't believe such rumors. Maybe the message got to you somewhat
garbled but at times you MUST change worn rear sprockets because the
chain will skip under load and not drive the bicycle. Don't change
what works and if you replace the chain in time when it becomes worn
enough, you can ride a road bicycle chainwheel 50K-100K miles.

You've got that backwards. The cassette wears out faster, since it has
far fewer teeth.

My cassettes last through 4 or 5 chains before they need replacing.
Others will have different replacement intervals.

thanx for the correction. I've got approx. a 1000 miles on my
Bike now. Was just wondering what I may need to "budget" down
the road. I do follow a regular cleaning and lube schedule for
my ride. So no issues with preventative maintenance.

Well, not entirely, but the small diameter and that it is the driven
sprockets that engage the chain with a light spring load that causes
the chain to skip (not engage). In contrast the chain is forcefully
engaged on the driving sprocket (with high tension) of we have had
pictures of worn aluminum sprocket teeth on this forum that would
never work on a driven sprocket.

I think Carl Fogel has some pictures on his web site. At least I
recall sending him a picture of a still usable ancient chainwheel.

Yes, that depends on how worn the chain is when it gets changed out.

Aaargh! More sleep, maybe even proofreading, or perhaps a
firmer click on the cut-and paste:

Thanks for the directory. That helps a lot. However, where is the
picture of your toothless chainwheel?

It shows up now in the "directory"--which is a Potemkin
village fraud that conceals a things and needed updating.

If you change your chain in time (before 12 full links reach 12 1/16" in
length) a cassette will last several chains. Good chainrings will last
several cassettes, although the modern Shimano ones are very thin and
become hooked more quickly than cassette teeth.

Although chainrings are usually aluminum, which is softer than the steel
used on the rear cogs, they typically last much, much longer because they
have more teeth over which to spread the wear. If you have to replace one
of the rear cogs, it is usually only the smallest one. Chances are you
won't have to unless you've been riding with a really dirty chain for a
really long time.

You'll know the cog needs replacement if the chain skips when you pedal
hard in that gear.
