    Cassettes/ Cranksets????

    How long do these usally last? I was cleaning my bike after a ride and notice that some of the teeth look like they are starting to wear (sp). The ones I have are stock and I have owned the bike for 9 -10 years. I imagine its time to replace them but with what? Do you need to replace the derailleurs at the same time?

    You can not assign an expiration date to a bike part. It all depends on your mileage and your riding habits. Do you tool around at 15mph on the flats or do you hammer up hills at over 20mph? Stress and wear will be very different. your chain will wear first, then your cassette and then your chain rings. Proper measurement of your chain and replacement BEFORE it has reached it maximum will allow more life in the other two components. Search how to measure a chain. Chain rings will usually appear to have a shark's look to the teeth indicating wear.

    Two ideas about the drivetrain; one is to wait until it's about to fall apart and replace the rear cluster; front rings and chain; the other option it to replace chain more often (ie, mesure the stretch). What happens is you stretch the chain then the chain etches the gears down so a new unstretched chain will not proprly run on your now custom gears.

    Your derailleurs should be fine you might need new pulleys but I doubt it. If you are hard on your drivetrain than a chain will last about 1000km and if you change your chain before you it gets worn out you can get 2 chains for every cassette. Get a chain checker. They're well worth it. If you get a park checker change the chain when it gets to .75.

    One thing that will make a big difference is how clean you keep the drive train. Cleanliness and longevity are most definitely tied to each other. People that are meticulous about keeping their chains and drivetrains clean can get some very high mileage out of them. But, if you ride in the rain regularly, or don't keep all the bits clean, you'll get less life. Rain introduces grit from the road into everything that gets wet on a bike. There's really nothing you can do about it, but, again, a regular washing helps a lot.

    As with all things concerning the longevity of bike parts, YMMV.

    Have your LBS check the cogs and chainrings for wear and if you replace them then replace the chain at the same time. It's probably a good idea to check the tension and jockey pulleys at the same time.

    I picked up a Park chain tool, and checked the chain, it is at .75, but it sounds like it depends on the make of the chain? when/why would the 1% measurement be used? BTW, its a Shimano HG73 chain.

    thanks!
