ebay bike mechanics

so I bought a 1985 Guerciotti SPX Road bike off ebay and first thing I notice after it arrived is the top tube is bent in the middle (see pics) ....... so I email the buyer to ask him about it and what did he reply ..........Seller's message:
"The "bend" shown in pictures 3, 4 and 5 are within normal tolerances for steel tubing on frames. Those tolerances are 1/8th of an inch. The brazed-on cable bosses aren't always EXACTLY the same height when brazed to the frame, so laying a ruler across the top of them doesn't show anything


I just had to share that

That's terrible, I feel your pain. Now I'm afraid to look for a new frame on eBay.

Wow! Nervy little so-and-so. He must have an all-purpose book of tolerances that he can instantly pull out of the hindmost portion of his anatomy when the necessity arises.

File a claim...
and please let us know his name so we can avoid him.

I know Cannondale frames (aluminum, of course) had some heat treatment curvature sometimes present in their frame tubes back in the 80's, as I remember helping my brother find a Black lightning frameset with the least amount of curved tubes on it from a dealer's stock back then...
Not sure what type steel tubing your bike has (Columbus SPX?), but I'm wondering if it has heat treated tubing that does the same thing???

Wow, that is shameful! Contact Ebay and open a dispute or take advantage of Ebay's "Buyers Protection". Question, did the seller in the discription mentioned the problem you discovered, with the statement "meets industry standards" is an indication that the seller was aware. Don't send the frame back without insurance and adult signature required and get a copy of the shipping acceptance with posted at the post office. Good Luck

The response definitely has an annoying tone, but isn't it fairly accurate for production frames? Do you take this to be crash damage?

Here was the auction, by the way:

yep that's the one ..... he had GLX tubing down on a full super record bike ...........if I were going to take a guess I would say we are looking at the press the garage door opener with the bike leaning along the door frame damage

Nah, that's from straddling the top tube at stop lights. That's why you need to know how to track stand.......

Tubes aren't always completely straight. What matters is if the alignment is good.

can you post some examples of non-straight columbus sl/slx top tubing since I have never seen bends like that in high end frames

Out of curiosity, were you able to eyeball that or did you specifically check when the frame arrived?

I'm not questioning your expertize regarding frames, but have you taken it to a professional bike shop to use their gadgets that they have to determine the frames straightness? I ask because I posted a thread about my vintage Pogliaghi, and some members were adamant that the fork was bent! I took it to several shops, and a Professional collector that has been collecting/selling for over 20 years, and they all confirmed that the fork was not bent! I would give that a try! All the best!

without being in front of the bike it is hard to see just by looking at the pictures ...........these two pics of the bent area show the tube is no longer "round" just near the middle cable braze on

Looks like some one use it as a stepping stool or ladder rung. Tubes don't get that way by themselves.

I find it highly interesting that he does not make mention that "1/8 inch is within normal tolerances" (did he make that up? Probably - after all, 65% of all statistics are made up on the spot) anywhere in his auction write-up. File a claim - and thanks for sharing the perpetrator. Lying by omission is still lying.

what is even funnier is that Columbus SLX tubing is .6mm and 1/8 of an inch is 3.17 mm so according to ebay bike expert the tolerance on an Italian bike is allowed to be off by 5 tube thicknesses

Tell the seller the bend is NOT within your tolerances.

That frame is bent. No question about it and don't let anyone let you believe otherwise.

Someone either sat on the TT or stepped on it or fell of the saddle or something.
