The Neutron(TM) Ultra(TM) are now a well-established symbol of success for Campagnolo(R) wheels.
Sought after by professionals and amateur cyclists alike, its characteristics are inimitable. Super lightweight on inclines and extremely reliable; they can be responsive when called upon, or comfortable against the hard pavement, even after hours on the seat.
The Neutron(TM) Ultra(TM) encompasses everything a cyclist requires.
Feature and benefits
The exclusive geometry of the polygonal rim
Allows for an elastic rim, which is both comfortable and extremely responsive at the same time.

Maximum wheel torsional stiffness. Spoke tension is maintained and guaranteed performance with the best aerodynamics. Stability even at high speeds.
Carbon fibre Hub Body
High degree of lateral stiffness - reduces the weight to the minimum.
cup and cone bearing
ball/bearing adjustment, reduces possible ball/bearing play, precision operation, maintains performance over time.
Increases the torsional stiffness, increasing reactivity at each change of pace of the cyclist.
