    I was on my commute this morning and my gears were slipping and at one stage seem to get a bit jammed. I know this is common with new bikes but how do I fix it. I thik it's about time I started to learn how to do things myself instead of running to my LBS.

    Cables on new bikes tend to stretch a bit. It is usually simply a case of turning the barrell adjuster on the rear derailleur a turn or two to get the right tension. Anti-clockwise tightens.

    If it's a new bike, it's probably just the cables are bedding in so there's a bit of slack which is messsing up the indexing. There should be a barrel adjuster on the rear derailleur which you can turn to take up the slack, but it will involve a bit of trial and error to get it right.

    If it's an old bike, then it is (sadly) far more likely that your chain and cassette have worn and need replacement.

    If you want to get into repairing your own bike, it's probably worth getting a book - I've always found Lennard Zinn's books useful.

    I've just done that, so I'll see how I get on later.

    Thanks.

    Had this exact problem last week after some rain. Bit of WD40 on the chain did the trick and haven't had any problems since.
    Its great for cleaning the dirt off too but do get real oil.
