Because there will be no stand-out, never-seen-before technical innovation in Beijing, more a case of some 250 components that make up the bike, the suit and the helmet all making incremental gains and, collectively, delivering world-beating speed.
Of those 250 components, only the pedals, shoes, sprockets and chains have remained unaltered and that was because the SS did not believe that it could improve on them. Everything else is new and better than ever before.
For this reason, almost every single one of Boardman's 250 components will have been used, sparingly, before. Throughout the past two years, they have been utilised on bikes in different competitions, fed quietly into the system so that if the UCI kicks up a fuss in Beijing, Boardman will be able to reply: “But you didn't mind before.”
Wait for the Olympic bikes! CB already winding up the opposition
