    How does climate effect drivetrain wear?

    The conditions in southeastern PA have been very dry recently. The trails, which are usually damp and slightly muddy, have turned dusty and dry. I noticed how much less of a beating my components take with less mud, sand and wet leaves getting thrown into my chain and components.

    I bought a new bike 4 months ago and ride it once or twice a week. I'm a casual mountain biker (or is that an oxymoron?) and I keep my bikes clean and in good working condition. Even so, the chain which came stock already looks beat and old. I'm going to replace it during the off-season.

    Conditions here seem to be pretty ripe to tear up drivetrains. I was wondering what kind of wear problems you run into under different conditions.

    Worst for me is winter, a cold snap with snow, the roads get sanded, then a chinook will melt the snow, followed by heavy salt to cut the ice.

    I can blow a chain in one or two weeks.

    When your drivetrain gets muddy it's basically coated in grinding compound, so yeah, things do wear out quicker. When you replace the chain, take a look at your rings and cassette. If the teeth are starting to wear or 'hook', you need a new drivetrain.
