I have built two other frames like this but this one has the added feature of the internal routing for the rear mechanical disc brake. The Ritchey breakaway/S&S coupler combo was an idea of a customer of mine about a year and a half ago. This new bike was obviously inspired by the two other frames I built.
The bike will have the new Sram wireless 'Etap' shifting system, eliminating the need for any der. cable stops.
The frame will be fitted to a Whiskey #9 fork. The Paragon Machine works 'Poly-drops' are a bit of trouble to work with but they offer a lot of choices for brake mounts or axle specs with just a change of the inserts.
