Cool. Thanks for the input.

Right now I'm planning on using an IRO track crank (because i have it in my parts box) and SRAM X.9 equipment in the back has been highly recommended.

I need a new frame choice though. I was all set on the Nashbar X Cyclocross frame until I discovered that it uses 130mm rear spacing which is a PITA if I want to run disc brakes without building up (more expensive) custom wheels. I need to find a new frame (maybe just a 29er MTB frame) so I can run disc brakes with an off-the-shelf wheelset.
