no shuttle for the shock...That looks like a 2009 Demo 8 II.........not a 2010.
regardless......it still looks like a 2009 doesn't it??????You took a lot of time to analyze this article. You should read the title of the article instead of judging by the bike color.
Low bb's are like steep head angles.....The funny thing about all this is that a 13" BB is not necessarily too low.
It is however too low on a demo which has a good bit of pedal bob and only ~12% ramp in shock rate. I smack my pedals enough on my D7 with a 13.25" bb, sub 13" must be lousy.
Maybe the next iteration will address this problem...

Same place as the 13.25 bb height on a Demo 7.Where do you get that ~12% figure from?
Well a bike that sits higher in it's travel when on the pedals (ie not a Horst linked bike, think mid high single pivot or VPP) would be less prone to bashing it's pedals given an identical BB height to a Horst link bike.Low bb's are like steep head angles.....
They will kill us all....
but in all seriousness how the the ramp up affect how low the bb gets? Are you implying that with little ramp the demo will just blow through its travel on every hit?
Seriously, are people just nitpicking now because they are bored or because they think it is a legit issue?Well a bike that sits higher in it's travel when on the pedals (ie not a Horst linked bike, think mid high single pivot or VPP) would be less prone to bashing it's pedals given an identical BB height to a Horst link bike.
AAAAAnd where was that????Same place as the 13.25 bb height on a Demo 7.
You still haven't explained how that 12% change makes you hit more rocks when you pedal... Wouldn't it being .25" higher make you less likely to hit rocks.. why does it prove your point though?Sorry I couldn't remember if it was 13.25: or 13.5".
BB height:
And the 12% figure is from, well, reality.
It ramps from 3.18:1 to 2.86:1 shock rate. So that's about 12%.
The BB height point is even more exemplefied by it being .25" higher than I thought.
You don't seem to sure about 2012.....Yeah that's basically the idea I'm getting at.
A bike that is less progressive will have a dynamic sag or ride height that is lower and "ride deeper in travel". Then when you add pedal bob on top of that, your pedals go smashy smashy.
It also depends on the shape of the curve, and more importantly how much the rate ramps from the sag point to the end of travel. For Example if the rate gets softer first then stiffer from the sag point, even with both bikes sagged to X%, the one with the rate that ramps the most thereafter would ride higher in travel.
PTW: Divide 2.86 into 3.18 and you get about 1.12. Hence the 12%. The two numbers I used to calculate that are from Linkage suspension program.
Oh and nothing will happen in 2012.
ummm lower than not at full compression?
haha yeah, that sounds about right.
I like Demos, i have had 3 (05, 06 and currently on an 08) the BB being lower, and the HA being a little slacker would be ideal.Seriously, are people just nitpicking now because they are bored or because they think it is a legit issue?
This sounds like people who just haven't ridden the bike enough to be used to the way it rides....
oh and what does the ramp up or progressiveness have to do with ride height? thats more a linkage factor the way you describe it....
No. Like 99.9% of frames out there, it is a rising rate...and that is (one reason) why it works well with fairly linear shocks(just about all current shocks). There are VERY few falling rate frames around (santa cruz seemed to be the last hold out)...and they require a quite progressive shock in either spring rate (small volume air shock), damping (5th), or both to function 'OK'....The Demo is a falling rate design .
