Columbus tubing

Yea, read that, thanks

My old Vivalo was Columbus 'Genius' tubing, can't find anything about it...

Lazy arse, just checked google ;-)

hah so what is the difference?

they never list Air arrrgghhhh

this is a minefield, Im getting a DSB nivachrom frame set sat, which "is a revolution in tubing construction, its was developed according to a new type of stress analysis that introduces a third dimension in a tubes butting" eh?
I just hope it rides well, feels light as a feather :)
@diable, you really have to dig to find the exact one you have. see it as fun...

I hate gardening ;o)

would be nice to know the history though as I haven't come across another frame like mine but I fear it will taunt and haunt me to me death lol

Very odd.
I was chatting to Fabrizio from Columbus only the other day about the tubing. We were both chatting about the weaknesses of the single bolt setup. Maybe its not columbus' design?

forgot to mention it has Columbus stamped across the BB shell.

Does anyone know anything about Columbus "Brain" tubing?
I know, it sounds strange but that's what it really says on the sticker.

Thanks

Brain - We strongly recommend Columbus Brain for cyclecross designs. This tube set is an excellent choice for creating a light, tough and strong cyclecross frame. Brain tubes feature round over-sized diameters that offer good resistance to accidental impacts. This allows for excellent durability for the life of the frame. Brain Tubes can either be lugged or fillet brazed. Large choice of wall thickness and butted diameters to strengthen your cyclecross frame. Brain tubing can also be used on either a road or track frame.

Literally Googled Columbus Brain Tubing, this was the second link...

Thanks. Not that I intend to do any cyclocross.
Further Googling tells me it is no longer in Columbus' range of tubing and dates from the mid to late 90's and suggests that:

• it was better than Thron
  
• it was not as good as SL/SLX
  
• it may or may not be about the same as 531
  
• buying a second hand frame made with it may or may not be a good deal
  
  

The above "opinions" came from another cycling forum found by Google so may or may not mean anything.

Anyway, who wants secondhand, stale forum opinion, I want new, fresh, opinions .... :-)

This is a new one on me. Anyone seen this sticker before? Maybe 3 means tretubi?
sorry 4 pic , can't see writing. It says "Aspessore Conico"

bump ^anyone know this tubing?

hi benny, a better picture would help, but:

the word "columbus" in quotes (although i have seen a very few like this, but mostly pre-1975)
the dove not being white (red dove was 1960's)

may mean it's not columbus, or possibly old pre-1970; have a look at this blog and perhaps post a question on it:

http://italiancyclingjournal.blogspot.com/2007/11/columbus-steel-tubing-for-frame.html

and a spessore conico ~ conical thickness, probably in context of: reinforced conical thickness molybdenum chrome steel

Anyone heard or have experience of Columbus endurance tubing? http://newyork.craigslist.org/brk/bik/3050698408.html

That should clear things up a little ;), although search results aren't to clear either...

Woops, feel like bit of a plonker but even with correct spelling hardly anything turns up apart from links back to my posts!

Though this pic does have the spelling as endurance http://2.bp.blogspot.com/_693JCT80K-E/TFvFNvE6jvI/AAAAAAAAB4k/qWVRA_UJ-1Y/s1600/+De_Rosa_Endurance_05.jpg

what age is the frame? I' ve a .zip file with all the columbus tube types in it but no mention of minimax.

Off the top of my head it sounds like a more lightweight version of their Max tubing or a slightly oversize dia tubeset that isn't elliptical like the Max version is, but this could be shite.

Can email you the .zip file if you like.

Max tubeset is surprisingly chunky coming in at 1.9kg compared to 1.67 for the EL

just found this:

http://italiancyclingjournal.blogspot.co.uk/2011/01/steel-lovers-columbus-re-introduces-max.html

is indeed a newer version of Max with different metallurgy.

definitely looks slightly slimmer profile to my Max frame, some prawny bikes on that blog too:

"The owner of this frame writes:

I think this is Somec’s Dynamic model. Most other Somecs in your blog are ProMax model.

The Dynamic model has a unicrown fork with dropped seat stays from the seat ‘lug’ and has MiniMax tubes in Somec catalogs available. The tubing decal on mine says Max but the 'D' in my frame’s SSN of D110 may well correspond to Dynamic (number is on BB and steerer tube).

The ProMax model has Max tubes, a microfusion fork crown & most all Promax’s have seat stays more traditionally situated on the side of seat ‘lug’. There is one ProMax with dropped seat stays but it does not have unicrown forks.

Who knows, mine could still be a ProMax simply due to its Max tubeset. I’ve gone through the Somec catalogs at Somec website to arrive at this estimation: http://www.somec.com/en/factory/vintage_catalogs/"

looks pretty-never seen a purple Bianchi before.

Funny that it's lugged though-all the others I saw on the blog were lugless with non-standard stays although I doubt that was exhaustive.

Carbon forks might give a better feel-the original steel ones are tres stiff and ahead steering is much better imhop. Feel pretty chuffed to have a MAX frame at the price i paid, seems like a real leap forward in the development of steel frames and I just love the form where the tubes join-some of the Merckx MXL frames go for a totally insane price too.

They were designed to be used by big sprinters for the most part so I doubt you'll have a weight issue, the weight of the frameset is also c. 1.9 kg with the steel forks so it's not stupid light.

As long as its being ridden and enjoyed I see no crime in it being used for a SS beater anyway!

What Columbus Tubeset has the best combination of strength and weight?

Lightweight enough to be enjoyable when road riding, yet strong enough for some cross abuse and occasional light tours?

zona tubing would be the right choose for your bike
