2010 Demo 8

7

Like there's a weight difference.

looks can be deceiving. My demo weighs less than 36lbs and pedals nicely.

Well if I cared and I spent more than $1300 bucks on the bike I could probably get it down to a reasonable weight, but I still can't imagine anybody racing on it. There are so many other bikes I would choose over a demo 8 if I were racing.

PS. I weighed it in on a hanging scale…49.7lbs. I am going to put my old funn launch pad seat on it to get it over 50.

Apples and oranges. Your demo 9 is not even in the same league s the new demo 8.

150mm back end is good for:

Being heavier
Fitting 3" tires

That's it. There is nothing else that a 150mm gives you that a 135 can't. Stifness, strength, chainline, it's all in the design.

Sweet, so they can have a wider bb and still use a 135mm hub. They have the technology. Why didn't they?

A certain fast Australians race bike has a 150mm back end [HTML_REMOVED] an 83mm BB. This requires custom stays [HTML_REMOVED] some extra-wide BB cups to fit the 83mm cranks as the BB shell of the Demo is part of a larger forging.
The fast Australians diminutive mechanic tells me that it makes no difference to strength or stiffness anywhere other than in the fast Australians head.
Seems to work for him though.

My guess would be that if you built up a second bike that was visually identical in every way but 135x73, said rider would do just as well.

These discussions sure get heated for differences I'm not sure we can really detect. I'll be the first to admit I cannot feel the difference between 73mm and 83mm; except for the nuisance factor when I buy a new frame and have to buy new cranks.

Fair enough. disregard my previous posts!

either way, the new one has a rad paint job and specialized bikes are generally pretty awesome.

its like a 12% difference, if your bars were 12% larger you would definatly notice.

yes.

I don't know about that. Is your Q-Factor increased by 12%? That is what you'd feel, not the BB shell being 10mm wider.

I have no idea what a Q factor is. All I know is id feel more stable and planted on a bike through rough un-even terrain.

seriously, look at how much 10mm really is. Unless you're clipped in, I doubt you regularly put your feet within 10mm of the same spot on the pedals.

pffft!

You don't get 5 kills on CIU with your feet in the wrong spot of the pedals Dave, everything has to be perfect. Not to mention the gnarly whippage.

Q factor is: http://en.wikipedia.org/wiki/Q_Factor_%28Bicycles%29

i test rode a demo8II on saturday. really low bb - hit my pedal going over a curb. took it down CIU, felt really plush. too slack and long for my taste though.

once you go slack, you never go back.
