from the same era definately
both are caad4 aero based
mine was his time trial bike for the 2000 olympics and looks nicer !

Yeah it's awesome, no doubt. I reckon you should buy that track bike for collection.

been watching it on an italian site for a while no price drop yet !

how much is it?

less than that ron cooper !
quite a bit less

aluminium alloys generally trade ductility for strength

...but reduces ductility. B-)

Must read more carefully, C+

Pretty sure my Cannondale was 130mm spacing originally.

I have a 3.0 from 92 with 126 spacing so I was basing my assumption off that. makes sense that a more modern bike is designed for more modern components.

australia I think!

is this in asia? there is one out there I saw before on 't web , if not it had same gruppo I think

Link please.

Yeah, mine is 95 or 96.

I was editing yours. Needed reinforcing. B-)

do not agree

There's a quill-to-AHead converter in there, that would disbar it even if the rest of the bike wasn't so obviously trying too hard.

So much wrong with that

My mid 90's 2.8 is 130mm spacing. Modern wheels went on it no problems.

That's my build on previous page, thanks for posting it here. I've sold it since that pic was taken but it's a '95 frame and the rear spacing is 130 mm standard. I'd never think about trying to cold set an alu frame.

record bottle cage ???

Yup:

That even offends my tastes so it must be bad.

are the head and seat tubes carbon effect steel, or carbon?

I like the wishbone stays. Agreed that the rest of it can do one.

wtf is carbon effect steel?

Steel tubes painted to look like carbon. I think I saw that on a Diamant once, can't find it now.

Depends if oversize thinwall etc.

My Vitus spread like butter but pretty thick walled narrow gauge stays. Super soft.

Aluminium is very ductile. Just when highly stressed eg. Cokecan thin, prone to cracking.

Also depends on mix as usually an alloy of.

No way my scandium Mash would allow 130 eg. Stiff as a board and stressed accordingly.

Alu and a lot of its Alloys are crystalline i.e. brittle. Hence the thought that frames are 'harsh' or 'stiff', no?

No.

1. All metals and their alloys are crystalline*
   
2. This doesn't inherently make them brittle
   
3. The brittleness (or otherwise) of an aluminium alloy doesn't affect its stiffness, for all practical purposes all aluminium alloys used for cycle frames have the same stiffness.
   
   

Aluminium frames made from modern high strength alloys exploit the strength to allow large diameter tubes, which make the frame stiffer at a given mass e.g. doubling the diameter while halving the wall thickness makes a tube about 5 times as stiff without changing the mass per unit length. You can only make tubes with that kind of extreme ratio of diameter to wall thickness from strong materials, otherwise they buckle.

*Metallic glass hasn't made it to bicycle parts yet, so we'll ignore it for now.

Yes, but there are still some alloys that are stiffer than others.
Same tube diameter and wall thickness steel tubes differ in their stiffness.

But I get that if for some reason there's an option of using more material to make the tubes stiffer, then make it wider, not thicker. As thicker tubes don't have as much stiffness as wider tubes using the same amount of material per length of tube.
