My newest crank in stock is the one of the picture: long pedaling but no bolts to attach the spider to the DS arm.
I successfully installed it on my BBright Cervelo and rode about 300 miles with it.
There is clearly a lack of stiffness coming from the spider which is not attached and maybe a little bit too much machined....
But the rest of the crank is awesome !
My weight is 415g verified in 130/175 and 93mm length spindle, which is the same standard of Rotor UBB cranks (3D+ series).
I feel a comparable arm stiffness to most of the Rotor series, it's lightweight and there is absolutely no creaking noises.
The only restrictions that I have is to avoid riding above 500W power in order to preserve the spider. So, no sprints, but already fast ascents, just enough to imagine the interest of a such beautiful product.
I'll visit Ted for the Interbike event and I'm now sure that we are very close to start a mass production.
hope the new spider being bolt on doesn't have this problem. i expect it to be Stiffer, noises free.
having a 900USD with restritions on Power output, and ride type, doesn't make sense!!!!
never the less, i would like to see a Stiffness test from some Lab or something like fairwheels did.
