More info later after I get it built, but here are some pictures and some stats:
Frame weight is 4.75lbs. including the Eccentric Bottom Bracket. My Fisher Rig, for comparison, is 4.35 lbs or so. Also this Curtlo is a about a half-size bigger than the fisher in frame size which accounts for some of the increased weight. Also the curtlo is made from steel, and the Rig is aluminum. But I am anticipating that the ride will be very sweet to more than make up for the weight gain. There should be enough tire clearance in the rear to fit just about any tire available currently.
