Head tube discoloration - worrisome or OK?
I just sent a question directly to TurnerBikes, but perhaps someone here also has some hands on experience... with frame discoloration:
I have a 2005 5-spot, and noticed a few weeks ago some discoloration at the headtube, just beneath and to the left of the Turner logo.
The bike did not get hit there. Perhaps the bike came like this, but I don't remember it. Perhaps it had some cable routing through there in the past, but similar cables on the top-tube just scratch the paint - not discolor it.
What do you think?
Is this the kind of discoloration that tells something serious (e.g. frame breakage on the way), or should I just continue to ride my bike and "be merry"?
Thanks for any advice!!!

It's hard to tell from the pic but the shot looks like cable rub. But if it's a discoloration, that's the first I've seen. Especially in the middle of the head tube. I can't think of how it could be stress related in that location. Impact related? Maybe but then there should be an impact mark as well , like a dent, ding or chip.
Maybe the bike was stored leaning against something that interacted with the paint? (Reaching here...)
FWIW that's almost exactly where I get cable rub on my Spot. But I have a clear frame protector there.

Agreed, can not see how it could be stress related in the middle front of a headtube. failures would typically occur around the back of the headtube around where the welds are.

It looks like the other cable (just to the right of your red circle) may be making contact. When you turn your bars hard right, that cable will get tensioned right about there. Twist your bars and see if the housing and rub spot line up.

If you want one DB, send you address and I will hook you up.
That's total cable rub, scuffs and abrasions will be a slightly different color. You should see my '03 Spot's black PC finish!!! Its looking pretty rough right now to say the least.

I knew this was going to come up. Now you're going to have a hard time riding it with all the people showing up to pay homage to the picture on the frame. Should have kept it to yourself.
