CX bike, sliders, the works. Silly, silly rotor cranks!
Apparently James is trying to wheeze on my gig with his identical garage door.
Edit: by popular request, some basic dimensions: Head tube: 150mm at 71 degrees (fork rake is 48mm, trail is roughly 68mm with 35c tires) Seat tube: 56cm (to top) at 73 degrees Toptube: 55cm effective, 8 degree slope BB drop: 70mm Chainstays: 43-45cm (min/max range of sliders)
The frame is built for 40c tire clearance and racks for nasty weather if needed. For all-around riding as well as hitting the dirt, of course.
