I'm just becoming an engineer and after taking Statics I can say it looks like it is made to better resist bending moment in the middle (like the bow in a big ol' steel bridge), but I think they need a 2 force member to go straight between the BB and the pedal spindle to actually have any effect? I bet its just to look cool (although maybe the designer thought it has better ergonomics for where your ankles/shins touch on whips or something.)
I am not an engineer, but if you happen to pay attention to the back crank, which would really help, the pedals are normally straight across, but with these cranks they are not. So there is some reason these are designed this way.
With its aerodynamics, it allows those who cant shift much less drag from the traditional block style crank. Works amazingly well when paired with a set of homemade pedals made from whisks.
It may look cool, but there is no advantage compared to normal cranks. So why create something which probably uses more material than a straight crank?
This is a stupid design. The position of both pedals is the same as a normal crank. If anything, the crank will keep hitting rocks in a rock garden. This is the best design to have a shitty looking crank after the first ride. Looks heavy too.
if any thing it looks like it would put more spring in the crank and being a DH guy thats the last thing i would want .. besides in the pic you can see that its realy easy to inproperly install them in balance .... so ya more cons to pros poor disign
Trust me, I'm an engineer.
