    New question here. rear derailleur. short or long.

    How do you know when you need a long or short rear derailleur. I think I'm going to have to replace my old one on my WCF.

    If you have standard mtn bike gearing with a triple ring crank than you should stick with the long cage. Even if you don't a long cage will serve you well.

    The cage length helps the dérailleur pick up the chain slack between the various gear combos.
