A few opinions on this board vs. 65,000 riders who need to get to work reliably. Enough said. I'll go with what works in daily life, which is why I have a Nexus 8 and am trying to destroy it since I was a skeptic.

Don't forget the premium red band version has improved needle bearings in addition to losing 10 oz's.

I don't own Campy or Dura Ace so I won't comment on their reliability.
