I dunno. I've been looking into options for fenderable road bikes which often also have the slightly longer chainstays, bigger tire clearances, taller head tube, a little more relaxed handling, etc... of an "endurance bike" and have come to the conclusion that the U.S. options mostly suck. The British seem to have figured out how to do it much better (well, the Lynskey Sportif looks ok).

Don't want fenders? Fill that generous gap under the brakes with some high quality 28-30mm tires instead. To me this type of thing is preferable to some carbon wunderbike with limited clearances that's going to look dated in 5 years.

Or go custom.
