NS1- SHIMANO 105 Zipp 303S - Overview
ABOUT THE NEW VENTUM NS1
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.
A NEW, SHARPER FRONT END
Leaning on lessons learned from the Tempus TT bike, we reshaped the NS1’s front end to be deeper and sharper.
- The leading edge now extends forward of the steerer, creating space for a
cleaner, more efficient airfoil where the wind hits first - A pronounced hourglass head tube narrows the frame’s waist to
reduce frontal area - Deeper airfoils on the fork legs channel air around the front wheel
and increase stiffness
The result is simple: a sharper, more efficient leading edge that’s faster through the wind.
