ZIPP 404 NSW

*** ZIPP ***
404 NSW
A lot can happen in a week in the bike industry!!
for example, at the beginning of last week, ZIPP said the 404 NSW was the 'industry leading aerodynamic performance wheelset' - by the end of the week, the 454 NSW had been released 'Zipp’s highest performing wheelset ever realized with wind tunnel proven aero-drag reduction and reduced side force at all wind yaw angles.'

Synical Steve, who rode out with us yesterday, says he bets they are the same, they have just developed the 454 NSW that shape to make them harder to copy!
You're probably not far from the truth Synical Steve!!
