It isn't a time trial on the hills or a century ride without Neutron™. 

 The profile has been optimized to increase resistance to lateral flex.
 The hubs used by the Neutron™ run on adjustable 15-ball precision bearings.

 Furthermore, the rear rim is drilled asymmetrically to permit recovery of the difference of the spoke tension on the left-hand side compared with the right.
