chain stretch, cassette wear and joining links
When it comes to chain wear do people generally agree that over 12 chai links 1/8th of an inch extra means you've left it too late 1/16th of an inch means it's time to replace the chain and any less means it's still got some life I don't really want to buy one of those little chain measuring things. Please excuse the use of inch units in this post. I'm not a foreigne or someone who won't let go of imperial. It just seems a tidy unit t use when talking about chains -- xisle |

Bush mechanic rule of bruised and battered thumb: Pull your chain awa from the front of your big chainring. If you can see daylight, then it' time to start thinking about a fresh chain. Lots of daylight? Thin harder, even about new chainrings. M "Chaincheckers are all very well, but they always seem to say th same thing" -- mfhor |

I don't really want to buy one of those little chain measuring things. FWIW, they can be less accurate than the method you're using. -- Shane Stanley |

That seems much more practical than swapping the chains every week/month as a recent thread suggested. Please excuse the use of inch units in this post. Chain link pairs are exactly 1", so its normal. |
