    Crack or scratch?

    Its time for everyone's favorite game - crack or scratch?!

    This is on the sidewall of a bontrager carbon rim. Holding it in my hands it looks like a scratch but the way that it goes across the hole like that makes me wonder if it could be a crack. I'm going to take it to my lbs and have them look at it but I know how you guys love (or hate) to play this game so have at it.

    No moss...

    Have you put your finger in the hole?

    To feel the end of the scratch?

    That didn't come out right!

    That'll buff out.
    Try buffing it by hand.

    Crack, ready for catastrophic fail... (someone had to take the other side, even if it totally looks like a scratch)

    Rims have spoke holes on the sidewall? Bontrager doesn't sound like they know how a bike wheel works.

    That's a scratch. Do the quarter test. Tap the rim with a coin going back and forth over the "crack." You'll know if it's a crack by the change in sound.

    Crack gets my vote, I love it.

    Drill that hole out big enough to stick your finger in there. Then you'll be able to feel the edge of the crack/scratch and know for sure. Why leave room for doubt?

    That's definitely a crack. If you use it you're risking catastrophic failure and huge medical bills. You need to buy a new bike. Safety first!

    This. To me it doesn't look uniform, either. BWDIK?

    That hole is for the hot gases to escape during welding the carbon. I know these things. I smart.

    I thought it was for injecting helium to make them lighter?

    Probably scotch, though I much prefer rye these days, specifically in a Manhattan. The last time I smoked crack it was a lot of fun until I lost my pants. My wife was pissed at me! Wait, were you asking if I'd prefer crack or scotch? Never mind.

    This is what a crack looks like.
    Broken, delaminated layers of carbon.

    You have a tiny scratch that is in the top resin/clear coat.

    Are you offering cratch snacks?
