Ti frame alignment?(15 posts)

Ti frame alignment?took
Dec 3, 2003 9:45 AM
Is it possible for a titanium frame to be knocked out of alignment as a result of a crash? I had always heard that this is not an issue w/ ti frames b/c the metal resists the bending normally associated w/ steel frames. is this true?

thanks.
I would think...PsyDoc

...that given a hard enough impact one could knock a ti frame out of alignment. Like you stated, ti frames "resist" bending, but are not impervious to it. However, if you were in that type of crash, then I think you would be smart enough to have the builder or a good LBS look at for you.

The reason I ask is not due to a crash, but from shipment. I sent a ti frame to a buyer who claims that the rear dropouts are not alligned. To me it sounds like the guy is mechanically challenged, but i wondered if it could have been possible for the frame to have been bent in delivery.
with UPS anyhting is possiblelaffeaux

The last MTB that I had shipped to me ended up with a dented down tube, and the fork was snapped in two.
Who knows what kind of wheel he is sticking in there!the bull

Maybe his wheel is not dished right.
Why does he think his frame(your old frame)is messed up?
It would be hard to mess up a ti frame without denting it!
Got a piece of string?Scollopini

You can check your frame alignment by pulling a long piece of string around your head tube and tie each end to your rear dropouts - pull it tight. There should be the same gap each side of your seat stays measured from the centre of the seat tube. This is a rough guide but will tell you if you have a problem or not at home without special tools.
Not sure if that will ...oldbutslow

tell you if the dropouts are crooked. There is, however, another alignment procedure at the same sight (Sheldon Brown) for dropouts. Easier to take it to a LBS, though.
Didn't ask if dropouts crooked - asked about frame (nm)Scollopini

asked about the drop outs:

thanks to all. i asked the buyer how he came to this conclusion and he said his wheel is pushed to one side when it is installed. he says it's still pushed to one side when he inserts the wheel backwards (cassette on non-drive side), which i guess rules out a poorly dished wheel. still can't beleive a ti frame could be knocked out of alignment during shipping...but i know for sure it was in alignment when i sent it to the guy.

is contact a bike shop in his area and explain to the mechanic the situation. Have the buyer bring the frame to his shop. At least you will have an "expert" and unbiased opinion on the condition of the frame. If it is in fact bent, you should offer to make good on the deal either by refunding his money or offering to pay to have it fixed.

As for getting money from UPS for the damage, good luck.

thanks. my idea was to do the same, assuming i can get UPS to make good on the insurance claim.
That would be difficult even for UPS...TFerguson

According to an article about a small Ti frame builder, he says that to cold set the frame 1mm after he has finished welding, he has to move the frame 18 inches.

Same story from Matt AssenmacherKerry Irons

Assenmacher is a nationally known builder, though he's pretty much out of the business now. Has built frames for olymipic medal winners, RAAM winners, etc. He said it was VERY difficult to cold set a Ti frame (4 foot long cheater and giving it all he had). Seems unlikely that shipping could have damaged the dropouts without seriously trashing the shipping carton.
