I am pretty sure I am goin to get the Kelly, but what I really want is a cuctom IF. I have a set of Dura-Ace 7701 cranks that I want to run with the inner chainring and the FSA chain guard on the outside. But I can not figure out for the life if there is a BB that will allow this with the Surly 1x1 hub. But I have never been so excited for a project, especially since I left Chicago for LA. I have mountains and all kinds of trails to ride, never found much in Chicago. But maybe I was not lookin hard enough.
