Skip the Fat bike crank.
I purchased a Fat bike carbon frame, Carbon wheel set, and the fat bike crank. The threading where the pedals thread into the crank arms failed within 1/2 mile ride. When I contacted Ican, but was told, I did this. I have worked on my on bike for the past 6 years, and this is my second bike build. I did not cross thread, and only tighten finger tight. I spent $1600, and Ican won't help me out with a crank arm. So far(4 hrs of riding), I really like the frame, and wheel set. Ican does not stand behind what they sell, so hope you don't get a dud.
