I have a question. I was looking closely at this bike: http://www.bikesdirect.com/products/motobecane/fly_TI_2x10.htm
When I blow up the picture there seems to be a little hole in the welding. Can anyone confirm? I'd imagine a small 'dink' in the weld is acceptable and won't harm the strength. I really like the price of this bike and just need help deciding.

You will not be buying the one in the photo, and all of the welds aren't going to be identical.
^^. . . or perfect. There will always be minute anomalies, especially where the bead is started and stopped; but as long as there are no out-and-out voids or slag pockets you should have no worries.
If you're really concerned, insist on the magnafluxing documentation for your exact frame when you place the order.
:D.

Yes that's right. I'll get a different frame. Do you think if I do get a small hole that water could get in? Maybe Ti frames don't rust though.

Oh man, small holes in titanium can be disastrous. The void in the surface over time causes a misalignment in the submolecular microstructure between the base titanium and the annealing zirconium atoms. As the grain structures of the two dissimilar alloys get out of phase, it causes the metal to exhibit characteristics of an event horizon in miniature. This in turn causes the frame to, quite without warning, implode on itself, sucking the attached components in with it to the point of irretrievability.

If you're worried about little imperfections in the frame, you need to buy a perfect frame. *cough*Yeti*cough*

There's something wrong with you and D!

...taking along your nuts on the implosion.

Sucked me right in. As a chemist, I was through the second sentence reading the third thinking, "Man this guy is good". Then read the rest. Felt like fish with big hook in my mouth.

too bad annealing is a heat treatment process and not related to any specific atoms.
"interstitial" was the word.

Yikes, first it's a small dink, and then your nuts go. Stay away from that frame!
