Sounds to me like your biased against the lefty. A fox 40 dual crown is
stiffer than a fox 36. Do you believe that, or do you need laboratory testing
to be convinced? There isn't any impact testing data or slo motion camera
footage out there as far as I know. If you search online reviews of the lefty
you'll find that the stiffness is a common and consistent compliment. If you
refuse to believe that then maybe you should ride one and see for yourself.
Overall I think many people are just plain biased against the lefty. They say
it looks dumb, it will break or fail, plus I dont think cannondale in general
is held in high regard by many aggressive riders. So people poo-poo what they
dont understand.
The simple engineering facts remain, the lefty chassis is superior in its
class compared to single crown because:
*Class leading Fore-aft stiffness
*Class leading torsional stiffness
*Needle bearings have much less friction than dried up bushings (especially under hard load)
*Reduced un-spring mass due to inverted design
*12mm less axle to crown for equal travel compared to single crown
And what are the drawbacks? It looks funny? Just on my last 2-3 points alone I
would place it ahead of a single crown.
