Ah, you also never have to wait long for an argument to break out where there is a fact vs marketing conflict.
It is a butt ugly crank. It may suit some bikes, some people may like it. If it does weigh 706g for the set, it gives Shimano users a lighter option. Substituting the RED crankset with this also makes RED a lighter groupset, and arguably better performing.
A 10% increase in stiffness means it will be nearly 20% stiffer than Record. Although in real world terms this counts for nothing, it is a nice thought to have when you are trying to extract every ounce of performance from yourself and your bike.
Alloy DA will still remain benchmark in price:weight:'performance' ratio
