Super sweet crank, light/stiff/affordable!

This is by far the best crank I've handled. I went back and forth on using a stripped down XT crank, a Stylo OCT 1.1, and a stripped down Noir for my 1x10 conversion. But when I saw the price and specs on the e.thirteen I bought it. I am running a Race Face single speed ring with MRP bb mounted 1.x guide and its great. The 30mm spindle with polygon interface translates to a very solid feeling set-up, I'll use it on future builds, can't be beat for the price. Its lighter than an XT at the same price and not much heavier than the XTR that cost $200 more.
Plus, it looks badass.
