    Paint flaw or Gusset Crack?

    So a little while ago I noticed what looked to be a crack in the headtube gusset on my Bullit. I looked a little closer and was able to convince myself that it was just a paint flaw, but now I'm not sure, so what do you guys think? From the looks of it, it could just be the clear coat, but I really don't like the way that it travels along the weld up towards the headtube. Any analysis would be helpful.

    Ok...... so how do I post Pics, since they aren't showing up?

    underneath where you write (under the "Post Icons"

    there are "Additional Options"

    upload your pic there unless it is already uploaded on a site, in which case you copy the image URL and copy/paste into the IMG button on the top of the text box thingy... or just put the image url in

    pretty easy...

    Its hard to tell without a pic, do you feel it when you pass your nail over it????

    To post pics you have to upload them using the "upload photo" just under the big black banner at the top. Then you copy the link they give you, its the web adress of your pic, then in your message, click on insert image then copy the link in the box that pops up.

    From your pic I would say probably not a crack, However I do not work for Santa Cruz so you might wanna get them to take a look. Their CS is excellent.

    It kinda looks like cable rub, but it doesn't make sense that it is so long.......

    stress??

    I am by no means an expert on this, but it does look like there has been stress on that area. kinda like when you bend aluminum back and forth before it breaks... get that checked out. it's definitely worth looking into.

    Looks like what sweat does to the paint, but because of where it is it sounds like as the person above said stress

    I'd say scratch on the weld because the line and color is too consistent to be a crack perfectly through all those weld spots. The frame part however could be stress on the aluminium like someone else mentioned. I broke a frame once cause I thought I had a scratch and the manufacturer didn't replace because they said I had been riding with a crack in my frame for too long and abused it. Be safe, get it checked

    get some rubbing compound and buff the paint a little....you will see more of the area. Then watch that area to see if that returns. If it returns then you got problems

    Hella gnar gnar cable rub brah.

    I can even see the culprit in the picture.

    Cracks don't usually run along welds like that. Buffing the paint a little will tell you for sure though.

    How could the cable in the picture possibly touch way over there up the weld?

    Heard from SC

    They told me that it's probably just the clear coat, like I originally thought, although if that's true I'd think I would be able to feel it with the tip of a pin. It has been pretty stable (not getting bigger or anything) for a couple of rides but I have taken a few materials science courses so I'm still not comfortable with it being there. Anyway, if the frame fails, I'll be sure to post pics.

    just sand it down and get rid of the cracks. If you cant, you know its deep in through metal, which i doubt. But since you're so concerned...

    Bouncy bouncy?

    I don't know. That's why I said sand it to be sure.

    Maybe cable rub is a virus.......or a fungus.......... It spreads if unchecked. Kind of like the stuff I've got growing on my nuts right now. In that case try toluene.

    I live in a bible conference encampment. Therefore the "act to which others refer" is impossibe. I only communicate via prayer through our great leader. Then he puts the sh1t on the internet for us.

    I'm thinkin it's just a straight up hygene thing........this whole "cable rub" issue. We're told not to do that either. But hey, you gotta live a little right?

    the best way is to sand it down...

    lightly, and see if it goes away. Also, try looking at it with a magnifying glass. Yours looks like a paint or clearcoat issue to me, but the only way to tell is to get down to bare metal and then hit it with a magnifying glass. Unfortunately, I know all this because I have a an old Heckler swingarm with a "small" crack in it- that bike is now my beach cruiser...
