I understand that unfortunately it is going to cost WAY more $$$. I wish it didn't, but I like the Vaya and don't like the orange of the complete. Plus, with the complete I'd change the handlebars, crank (I want lower than 48/34. plus, would probably then need a new FD), wheels (at least the front for dynohub), brakes (would prefer BB7 over BB5), and maybe the shifters in order to work with the new crank. Usually the LBS will swap out parts at cost, but they can't get a Vaya (OOS) and I am still not fond of the Orange.
I'll use it for commuting (but my commute is only 2 miles), recreational riding (~40-50 miles), will eventually do some centuries, and it will see some fire road/gravel. Also, eventually some short touring. I already have the Ortlieb panniers, gear, etc.
700c wheels. I mentioned SRAM because I liked the 39/26 or 42/28, but if Shimano has something similar for cheaper I have no problem with that.
