Some maintenace questions

On my road bike how often should I replace the Chain, and Cassette ?
I ride about 100 k's a week.
Is there a set rule to this ?

not really, as variants as to how many times u change gears, maintenance of the running gear etc impact their life.

if it starts to shift badly, skipping over when shifting under load etc, it might be time to replace them

Your LBS will have a tool to measure if the chain has stretched at all. If you haven't had this done for a while I'd recommend you get them to check it.

There are three schools of thought on this.

I belong to the first school of thought, that says cassettes and chainwheels cost more than chains, and that it's worn chains that stuff cassettes and chainwheels, so replacing the chain well before it's worn out will prolong the life of the other two. I generally measure the length of 12 chain links, and when that's over 12 1/16" I replace the chain. If the new chain is noisy (or jumps) on the cassette or chainwheels, then I replace these parts.

The second school of thought waits until the chain is stuffed (measures more than 12 1/8"😉 and replaces both chain and cassette together.

The third school wants nothing to do with any of this, and waits until teeth snap off chainwheels and the chain actually breaks before taking replacing the whole drivetrain.

A lot depends on what level of noise/poor shifting you can put up with. I can't deal with a noisy drivetrain, so I replace bits often. Others don't notice there's a problem until their cranks spin freely.

The rest of us just use a bit of lubricant to get rid of noises.
