custom frame tubing questions.
 
I just have a few questions that i can't seem to find the answers to by searching. trust me, i've been trying for about 3 days. I was wondering what the seam in true temper tubing is like. I guess to say how prevelant. I've never actually seen any, but i hear it's good stuff.

and, why can't i find dedacciai tube prices online ANYWHERE. grrrr...

thanks

Check novacycles.com for Deda tubesets and single tubes.

xthugmurderx 12-05-05 07:15 PM

yeah, i checked that, i guess i should have said zero and zero uno. i dunno, just curious. thanks though!

dolface 12-05-05 07:18 PM

pm donwalker, he's got the info.
(might take him a day or two to get back to you, based on his earlier thread he's kind of busy right now)

xthugmurderx 12-05-05 07:19 PM

will do, thanks, i was just hesitant to do that sort of thing cause i can't give him the business. but if i could...

I believe Dedacciai changed dropped the Zero and Zero Uno names and switched to the new alpha-numeric designations. Though I'm not sure if EOM16.5 and SAT14.5 are the same as Zero and Zero Uno or if there have been (in?)significant changes or what.

xthugmurderx 12-05-05 07:24 PM

they are...just a renaming

mcatano 12-05-05 07:29 PM

Then I'm confused as to what your problem is... there are prices for dedacciai tubes on novacycles.com.

I have built two frames with TrueTemper OX Plat/Verus - no seams. I think you'd be hard pressed to find high quality tubing WITH seams.

I think _all_ true temper steel is seamed.

The 411 on Seamed Tubing

Joe Bringheli also sells deda tubing.

True Temper tubing (in order of "fancy" to "less fancy"):
S3 - seamless
OX Platnum - seamless
Verus HT - seam
Verus - Seam

All great stuff. Seamed tubing: there is nothing wrong with this....works fine and you cant see a seam at all unless you look inside the tube, and even then its barly noticable.

Dedacciai tubing - sure the names changed, but still the same stuff.
I still call it Deda Tre, Uno, and Zero
Some typical frame kit prices for this stuff (8 pc set)
Zero - $95-115
Uno - $65-80
Tre - $50 or so

I stand corrected. Shoulda looked closer.

it's seamed; that's how the pipe is fabricated.
it's a layer of metal, rolled, and turned into
a tbe by welding it shut. afterwards, the weld
is completely removed by mechanical means.
at the end of the day, there is NO seam.

xthugmurderx 12-06-05 07:03 AM

i don't know how you found that, i must be ********. thanks to everyone that helped out. That is definitely the info i needed. now to decide between ox platinum and mixed deda sets. thanks again.

What Richie-issimo said.

It's really a remarkable process. The weld is made via rollers that pass current through the lapped seam. No filler material is added. And the tubes are then 'cold worked' to restore the grain. As RS said, this is how it's done.

is this how it has always been done?

back in the "old dayd" were the tubes actually welded closed with filler leaving a visible seam?
Seamed tubing must have gotten a bad rep *somehow*, no?

just curious.

My badly conveyed point was that the welding of the sheet into a tube is done via a process that most of us wouldn't recognize, since it doesn't include things like the addition of filler material.

Indeed, some tubing is made with a seam that's visible.

But modern DOM tubing is not that. It's processed post-welding and that processing is done to make the seam identical to the rest of the tube. Those tubes are placed into high-pressure and structural uses where they're called upon to preform without fail.

I think that there's a perception that seamless tubes are somehow better because they lack a seam. In fact seamless tubes have their own set of production irregularities.

my frame is being built using true temper OX platinum. how does this tubing compare to deda zero?
