2010 Demo 8

Remember guys, this is not the old demo 8. This is supposed to be a racing bike, not a freeride bike. If you concerned about hitting your cranks on things, this bike has like a sub 13.5" bb, so your out of luck.

So with it being such a huge claimed difference, are you saying that you could hop on any bike and immediately say whether is was a 68, 73 or 83mm bb shell? I think you've been drinking the marketting kool-aid.

after demoing bikes last week, its eazy to tell 73 for 83. with all the specialized bikes a tryed my legs kept hiting the seat. and i just didnt like it as much.

with the bmx cranks on my bike i run them spaced out almost 1/2" wider then the normal 83 set up. it feels better.

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.

The chainstays are very short though, the head angle can make it feel killer stretched out if your not used to it.

when i moved from a 29" bar to a 31" bar it felt great. trying to go back to a 27" bar just doesnt feel right.

same thing with crank width. i miss the 100mm bb from my old giant.

you'd get used to it.

i would have liked to take it down something techy like ninja cougar/karate monkey but due to the long lineups was only able to fit one run in.

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.

The Demo 7/8 both use a 135mm rear hub with a 6mm offset to the non-drive side. This theoretically makes a no-dish wheel, which is theoretically stronger.

As a 73mm Bottom Bracket shell is a 50mm chainline, an 83mm bottom bracket shell requires a 56mm chainline.

With the Demo's 6mm offset rear end, you should have a 56mm chainline crankset for a proper chainline. Several companies make this little conversion bit. All 83mm Raceface cranks can be converted with a special kit, and Truvativ makes a longer spindle Howitzer BB that works as well.

Give this man a case of Pil.

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.

I don't know how significantly different a demo 8 feels over the 2006 demo 9 I have, but there is no way in hell I could imagine anybody RACING on that thing. It pedals like shit, weighs 50lbs, and steers like a tank through anything technical. With that said, it's the Toughest, stiffest, strongest, most confidence inspiring bike for a regular old hack like myself I can imagine. I feel like superman on that thing. The old point and shoot method never felt so smooth. And as is evident from Lee[HTML_REMOVED]#8217;s pictures from Lillooet of me dropping 15 feet to flat, you can bottom that thing straight into the ground and ride out like it was a curb.

I haven't ridden it, but just by looking at the frame it doesn't look a whole lot different than mine so I can't imagine it rides significantly differently.

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