Ventum NS1 - Dura Ace Di2

ABOUT THE VENTUM NS1 DURA ACE Di2

The third generation Ventum NS1 is lighter, stiffer, more aerodynamic, and designed to fit better. Engineered to be confidence-inspiring at speed yet aggressive in corners, it’s the bike you’ll reach for on race day or big days alike. 

We used higher modulus carbon and a new frame layup to shave over 200g from the frame, and completely redesigned the front end of the bike to be sharper in the wind. The leading edge of the bike has been extended forward of the steerer, creating space for a cleaner, more efficient airfoil where the wind hits first. We’ve also added a pronounced hourglass head tube that narrows the frame’s waist and reduces frontal area.

The result: A sharper, more efficient leading edge. 

The geometry is aggressive and race-inspired, but we’ve added reach and stack — especially on the larger sizes — to make the fit friendlier to a broader range of riders. Not only does this make the bike more comfortable, but it helps riders settle into a cleaner aero position and hold it longer. 

This version of the NS1 comes with the top-end Shimano Dura Ace Di2 electronic groupset, ZIPP 353 NSW carbon fiber wheels, and the Ventum CR2 carbon on-piece bar/stem combo.
