    Ghost Shifting (Kinda')

    The bike works and shifts fine while riding on flat ground. However, during climbs when the drivetrain is under heavy load, the chain starts slipping/shifting/jumping around. The deraileur doesn't actually shift the chain to a different cog, though. I've been told that it could be a bent deraileur hanger.

    Any thoughts or advice would be a big help.

    Thanks,
    Kyle

    ok, well, let's start with the questions:

    how old is the chain?

    cassette?

    chainrings?

    what kinda bike (brand/model)?

    how old are the cables and housing?

    what type front/rear derailleur?

    and lastly, what kinda cranks (brand and/or type)?

    a bent hanger can cause problems but it's usually only if it's bent really bad.

    cool avatar. hehehee

    alright, bike is a 2000 Specialized Stumperjumper Aluminum frame, etc.

    cassette, chainrings, and chain are original to the bike...

    cables and housing have been replaced about a month ago...

    xt front der., xtr rear der.

    specialized strongarm cranks

    Thanks for your help...

    if the bike is a 2000 and the drivetrain (chain, rings, and cogs) is original, then you might have a completly worn drivetrain.

    9 speed i assume???

    if this is the case, 9 speed drivetrain rarely last more than a year and a half.

    so, time for new cassette, rings, and chain.

    also, double check by asking the shop to take a "chain checker" to the chain and see how far it's worn.
