This is sort of a bummer...
I dropped my wrench today (it was in my pocket after using it in my lab)
right after I unlocked and walked my bike over to the curb. I leaned it
against one of bollards that keep cars but allow maintenance cars to
come up to the civil engineering bldg. As I was picking up the wrench,
my bike fell down. I picked it up, and found this:
http://www.flickr.com/photos/p_myron_h/tags/dent/
It's a steel bike (Butted Reynolds 520 tubing). The deepest part of the
dent is 325 mm from the center of the head tube; actual top tube length
is ~550 mm. So I guess this dent is in the section with thinner walls.
So the million dollar question: Safe to ride? My gut says yes, but you
never know.
Thanks in advance,
\\paul

Of COURSE it had to hit just between the inner-tube wrapped sections.
Makes you want to shake your fists at the sky, doesn't it?
I've got worse top-tube dents on a track bike and an mtb that have
seen a lot of hard miles since their respective incidents without
failure.

Thanks for all the responses, y'all. I'll think I'll just leave it as a
part of the "urban camouflage" mentioned above. I guess this is what
happens when you start to ponder selling a really good bike.

We had a long discussion here about those bollards. I'm not surprised
that they are even more dangerous that previously argued!

Yup. Life is dangerous.
You've heard from the experts who see lots of bikes. My Oldsworth (ca.
1980) fell over (or was pushed) and took one in the side of the top
tube. Similar nasty looking, not a happy day-- I like that bike, for
all the hard use and other inci-dents (just paint, prior to the t-o).
Many problem-free miles as fixed since. I took it into the ULBS for
some dent-and-lip-service soon after the Fall (don't go there no mo')
and the resident mouth-in-chief ran some straightening blocks around
it, just to take a little of the sharpness out of the dent. Spoiled
the paint (that was the joke, ha ha) so I wouldn't even bother with
that. Yeah, look at what Colnago and others do with crimping tubes, as
long as it's not the coke-can type dent from running into something,
you're probably OK.
(As long as it's there and all) "Hallmark of authenticity" for a
'muter. --D-y

ugly? yes. mechanical problem? no. check out that huge-ass dent in
your chain stay if you need reassurance of mechanical fortitude.
oh, and if you're tempted to bondo, be careful sanding it off
afterwards. you can rub through the lumpy bits of the metal you're
over-zealous.

My neighbor's bike boom ten speed has a 520 sticker.

Bondo, prime, then some automotive lacquer--you'll still see it if ya
look close, but at a glance, it'll be invisible.
What kinda wrench does that kind of damage??

Ick. Nasty dent. But fortunately it's on the top tube, and top tube dents
rarely cause catastrophic failures. It will probably go quite some time
without trouble. Keep an eye out for any cracks. Hopefully Reynolds 520 is
simply so soft that it easily dents, without becoming brittle. Not a good
tubeset to build something really light out of, but these tube sets weren't
really light.
No way to really know from a photo; take it to a shop that's competent and
see what they think. Doesn't look worse than a lot of bikes we see come in
that people commute on and take on CalTrain.

Ugly, but really only a cosmetic issue. That must have been a heck of
a wrench, though!
If it bothers you a lot, run it through Bicycle Research's frame blocks
and fill anything left after that with solder. You'll want to repaint
to prevent rusting.
If it was my commuter bike, I'd just leave it. Part of the urban
camouflage.

I just rolled and filled a bigger one on a classic Gios Super last
night. No worries, ride it with confidence.
Probably.
Reynolds UK doesn't think there is a tube called '520' but some Chinese
vendors advertise such.

memory lapse perhaps. MAybe they should take a look at their old
documentation where it was listed side by side with 525
