His bike is 1 1/2 pounds heaver
Conversely, I went 'all in' but only because I gambled and bought frames and wheels from China and my Dengfu carbon disc crosser with Farsports carbon tubulars is ~1/2 pound heavier than the Ridley X-Night which is now a pit bike, albeit with carbon clinchers.
he claims the braking is no better if not worse than his cantis and not as good as his mini V's.
From my perspective, while dry braking on flat terrain is not appreciably better, at races this past weekend (non UCI) on a course layed out on rolling hill side terrain and featured several high speed downhills. On the descent despite a couple chicanes, speeds got pretty high yet braking with Avid BB7's and 160mm rotors was consistent and allowed me to brake much, much later for the s-turn at the bottom of the descent than those without disc brakes. The course also included a nice drop off down a somewhat steep embankment which of course was immediately followed by a 180 at the bottom, and while myself and several others were able to ride the 'runup' in practice, it was faster to dismount and run back up. for the race, many dismounted at the top and ran down as several who tried riding down were not able to maintain control as brakes locked up or simply failed to slow them resulting in an overshoot whereas discs allowed me to roll down while easily controlling speed without locking the brakes. Unfortunately the advantages gained on the descents and such were negated on the backside of the course where we snaked our way back up the hillside with barriers and double sand pit not long after reaching the hilltop.
