Actually, you should think about the Sachs PC89 or -99. Love that quick connector! From what Sheldon
says, the power links fit Shimano chains too if you really HAVE to have Shimano.

How many chains will the cassette out live?

If you replace the chains in a timely fashion, the cassette will outlive several chains. If you wait
till the chain's worn the teeth on the cassette, and the chain's all stretched out, the cassette and
the chain get replaced at the same time.

The least expensive method to test whether you need a new cassette or not is to buy that new chain,
install it, and see if it starts skipping. No skipping = no new cassette. Make sure you really stand
on it a few times in different gears that you like to ride just to make sure that it won't skip.

The cassette is gone when that happens. I use my cassettes for 8-10,000 mi. I don't get slipping but
the snap in the shifts deteriorates slowly. It's only when I mount a new cassette that I really can
tell that the old cassette is worn.

I would imagine so. After a season? On a chain that was already used? Too long, unless your season
consists of rides to the ice-cream shop only.

You should at least be checking your chain regularly after it has 2000 miles on it. I regularly
replace mine at about that mileage. If 12 full links measure more than 12 1/16", replace it.

But buying a used bike, I would replace the chain immediately. I'd also replace the cables.

It doesn't matter. Fancier chains are prettier, not more durable.

Depends on how worn the chain is. As the chain wears, it accelerates wear on the cassette itself --
and the chainrings. If you try to get 4000 miles on a chain, your cassettes will also need replacing
that often, and the cahinrings will not fare much better. If you cut chain replacement to 2000
miles, cassettes should last for several chains.

If the chain is kept clean and measured regularly, then replaced when the 'stretch' is about 1/16 of
an inch-many-if the chain is really toasted, your cogset probably is too-

about 3000 miles or so-like the oil in yer car-change before the oil is not 'oily' anymore-

There's only one objective way to determine if it's time to replace a chain; measure it. See the

Your choice. I've been quite happy with Dura Ace chains.

This depends upon how long you let a chain go before replacing it. If you keep your cogs clean and
your chain clean and lubricated, and don't let chain wear get out of hand, a cassette will outlast
a number of chains. I have a Dura Ace cassette that's gone over 40K miles and has seen at least
three chains.

I just exchanged my worn out Ultegra ( 85% worn according to measurement) chain for a new Dura Ace.
The price difference was only a few bucks but it feels like the DA chain shifts quicker. Maybe
that's cause it's new and the LBS told me it would but it sure felt like it.

Replace the DOTs to reply

Thanks for the input. I went out and measured my chain, and it looked to be spot on 12 inches as
it's supposed to be.

Seems to me that the only problem is shifting down to the smallest 11 tooth cog. That's probably the
toughest challenge.

Does length measurement actually account for side-to-side play? The side-to-side play seems to be
the problem when moving across the cassette.

Thanks.

That could very well be due to friction between the inner cable and housing, or inner cable and BB
guide. When shifing to the smallest cog, you have minimum tension on the cable.
