I saw upclose one of the new Dura-ace cranks in the display case of my lbs for the first time today. I want me one...not for vanity, but because they struck me as the very pinnacle of perfection. Outboard bearings..and the crankarms(!) -sensuous, elegently curvaceous, polished steel (-aluminium ). I want to remove the 39t chain-ring and put them on my track bike. Can anyone see any reason why I shouldn't? Please share
