Replace whole chainset if replace front chainring?

Hi Russell,

Thanks loads for your reply. Actually, my chainset is all one piece (or at
least it was!). It's on my 2002 Trek 4300, for which I paid £400. The
bottom bracket is separate though (but the supplied BB is crap too).

Thanks,

Jack

Hi,

I need to replace my front chainring 'cause it's broke. Will I have to
replace my entire chainset? People have told me that the entire
chainset
stretches with use and so if you replace one component, you have to
replace
the whole lot. I've probably used my bike for at least 1000 rides.

Assuming its a modern, not lowest end, crankset, then you can just
replace the chainrings individually. Chainrings wear a long, long
time. Much longer than chains or rear cassettes. On really low end
bikes, the crank and chainrings may all be one piece. Along with the
bottom bracket too. In that case you would have to replace everything
at once. But assuming you bought the bike in the last 10 years and
paid over $300 for it, you can replace the chainrings individually.

However, it may be cheaper to buy an entire new crankset. Individual
chainrings seem to cost about as much as an entire crankset, including
both chainrings.

you should be able to replace the broken chainring w/o any problems.
the rest of your drivetrain should continue to work fine.

Note that the term "chainset" is usually used to denote left crank,
right crank/spider and chainrings. I think you mean should you change

I thought this was the "crankset"?

Thanks for your advice, everyone. I've just placed an order for Shimano LX
M571 splined crankset and a 121mm LX ES51 splined BB. Goody!

Jack.

It is. It's the chainset too.

Ok, thanks; I've never heard the term "chainset" used to mean the same
thing as "crankset".

1000 rides on the same chain?!? Even if you only did a mile on each ride,
that's an awful lot of use out of it. Put it out to pasture.

If you are only getting 1k miles from your chain, you are doing something
wrong. I've gotten over 15k miles out of a chain when I sold the bike it
was on. Keeping it clean and lubed is important. If all you do is lube
your dirty chain, then 1k miles is a lot.

Wow! What a cross-post list!

There was a recent semi-scientific experiment done by one
rec.bicycles person which makes that advice questionable. He used a
chain with two quicklinks; he cleaned & lubed half the chain
regularly, and the other half he just kept adding lube without
cleaning. The cleaned half was slightly (barely) _more_ worn than
the half that was not cleaned.
