    On a seemingly new Mountain Bike, my gears have stopped changing correctly.
    I will be on the 7th gear(The smallest cog on the casette), then change to the 6th only for it to not do anything. I can however, change to gear 5, then it will change to 6... I can go to gear 1 just fine.

    Any advise?

    I've also noted that changing from the biggest cog doesn't have that many problems, but once I go to 6 it will slip down to 7 if this helps.

    If the tension does not work takes look at the detailer. Mine had a similar problem and what I found was I bent it ever so slightly, you could see the chain was riding on a slight angle and it would do ghost shifts. In 6 and 7 but not in 5th or Iower,l was able to straighten it out and the chain did not run at a slight angle no more so no more ghost shifts. Hope this will help

    Check that your cables are tight when in the smallest cog. If you can't retune it yourself, I think you should take it to your LBS and ask them for a quick lesson as the fix it for you, most wont mind if they're not busy. Also check out youtube for tutorials.
