Dom, that link is for the "Dirty Disco" carbon fibre cyclo-x frame, not the Ti in the vid.
As for the brakes, the Avid BB7 will be a lot more powerful and more reliable ( not as affected by water & crud ) than cantis and a lot easier on maintenance than hydraulics, albeit not as powerful.
Steve, definitely cable operated Avids, just look at the closing sequence close up of the front hub.
