This is a first for me , at least in one way-this frame is built for a flat mount disc caliper, one I haven't even seen yet. The customer for this frame will be doing tech demo's for Shimano and the bike will have the new Dura Ace Di II disc group.
Most likely there will be a tapered Enve road-disc fork on it. The frame is just a hair under 4 lbs. making it one of the lighter steel disc brake frames I have ever built.
If the owner winds up not liking it that won't be a problem......it's my size !
