I've been thinking of a cyclocross bike for commuting and riding on the roads of Vegas. I've tricked out my Trek Superfly to the point now that with all the wrench work, I could have built a much nicer and cheaper Chiner than what I have, but still love my bike. Anyway David, can you please post yours once built? I've got a Sram x1 drive train and love the idea of a wide range 1x11 or 2x11. I'm not as experienced with road stuff. Do cyclocross bikes use road drive trains, or MTB? I understand SRAM has the same spacing on their sprockets for MTB and road. Did you end up getting the frame with chain stay brake mounts?
As a side note, may not be many cyclocross venues in Canberra, but I loved the month I stayed there. Beautiful weather in March, got to see a bit of the city, watched a great Brumbies match, etc. I loved that unlike Washington DC, it's not ultra congested. Getting to "walk" on Parliament was pretty sweet too!
