The 2026-present Ventum NS1 is a substantial redesign rather than a light refresh. Ventum retained several practical features from the previous platform—T47 threaded bottom bracket, flat-mount disc brakes, UDH compatibility, full internal routing, and clearance for 700x35c tires—but reshaped the bike around a more aggressive aero front end. The defining visual and functional changes are the deeper leading edge projecting ahead of the steerer, an hourglass-shaped head tube, and deeper fork legs, paired with a lighter higher-modulus layup. That combination places the NS1 squarely in the modern aero-road category: a race-oriented bike that still acknowledges current expectations around serviceability and tire clearance.
| Stack | 541mm |
| Reach | 388mm |
| Top tube | 553mm |
| Headtube length | 133mm |
| Standover height | 770mm |
| Seat tube length | 473mm |
The NS1's geometry is contemporary but not extreme. Across the core sizes, the bike uses a consistent 410 mm chainstay and 69 mm BB drop, with a 73-degree head tube angle on M through XL. Reach numbers are moderate for an aero road bike—388 mm in M, 397 mm in M/L, 405 mm in L—while stack rises from 541 mm in M to 615 mm in XL, reflecting Ventum's stated move toward slightly taller stack and reach, especially in the larger sizes. In practice, that should give riders a race-capable position without pushing the fit as low and long as some pure WorldTour-style aero frames.

The NS1 range spans from a $5,599 Rival AXS model to flagship builds at $10,999 for Red AXS and $11,299 for Dura-Ace Di2. In the middle of the range, Force AXS is priced at $7,599 and Ultegra Di2 at $7,899, giving buyers a fairly clear split between more attainable electronic-shifting builds and premium top-tier options. The pricing structure suggests Ventum is offering the same core frame platform across the line while letting drivetrain level define most of the jump in cost.
