    Crack vs scratch.

    How can you be sure it's a scratch and not a crack?
    Noticed a little creaking on Saturday. Today I rode on pavement and Very noticeable creaking.
    Can't be sure if it's a crack at top of bb outside edge of DT weld behind chainring. Can't get a picture where you can see it.
    I don't jump, drops or anything crazy. Boring by most mtb'ers standard as I keep both wheels on ground. If I did then I would be more sure of crack. I am heavy, geared up maybe 290lb?
    Bike is '11 Diamondback Overdrive 29er I bought @ Performance.

    I had a creak for years and it turned out the creak was a weld with a crack in my seat stay I am not as heavy as you but ride hard uphill. All you can do is keep on riding and hope for the best. This is where a good warranty and shop will help out if it fails. With such a small area it's going to be hard to tell if it's a crack unless you can see some flex. Where is the area located?

    Outside weld edge where DT connect to BB on chainring side.

    Checked manual. Lifetime warranty (original owner) on frame. Going to call performance tomorrow and see what can be done. Store is 1.5 hour drive away.
