Hmm, so my new bike is all built up for a race this sunday except the cranks. I've been training with my powercranks but because of a shipping mixup my crankset has not arrived. i have bar end shifters (dura ace 9 speed)... can i just pop an old triple front chainring on there and presto? i'm guessing i might need to swap out the Bottom brackets, any advice on doing this. it's not really a race of great importance but i'd rather take of my PC's then not.

let me know any advice! i'm going to be doing it tomorrow.
