VENTUM NS1 RED AXS

No reviews yet Write a Review

We believe in climbing big mountains and dauntingly big rides, and that both should be accomplished as fast as possible. That crosswinds and corners are opportunities, not obstacles — and thus should be dealt with at eye-watering speed. 

 

We believe that a good road bike should be able to handle all of the above and then some, so we built the NS1.

 

The Ventum NS1 Rival AXS is our high-performance road racing machine. Built with a SRAM Rival AXS electronic drivetrain and ZIPP 303s carbon wheels, it’s our expression of what a road bike should be.

ABOUT THE VENTUM NS1 RED AXS

An all-rounder with aerodynamic elements, a lightweight all-carbon frame, and beautiful styling, the NS1 is a bike in balance. Its super power is its handling: Our engineering team leaned on their collective decades of experience in carbon fiber design to carefully craft the carbon layup of the NS1 — creating a frame that’s remarkably lively yet confidence-inspiring at high speed. 

 

The geometry is aggressive: Low and long for riders looking to get their torsos out of the wind and for an aggressive pedaling position. The frame also features a Universal Derailleur Hanger (UDH) for ease of replacement and compatibility with SRAM’s direct mount system. In the name of versatility, we also gave the NS1 tire clearance up to 700x35c. Its handling, stability, and larger-than-average tire clearance means it's at home anywhere from smooth ribbons of tarmac to friendlier gravel. 

 

This version of the NS1 comes with the SRAM Rival AXS 12-speed electronic groupset. It includes ZIPP 303s carbon fiber wheels and a ZIPP alloy cockpit. 

 

WHAT YOU GET

• SRAM Red AXS 12-speed electronic drivetrain 
• ZIPP 303 Firecrest carbon race wheels
• ZIPP alloy cockpit 
• A full carbon fiber frame with intuitive internal cable routing 
• Tire clearance to 700x35c 


VENTUM CUSTOMER SUPPORT + RIDE READY SHIPPING

 

Each Ventum bike begins life at our facility in Heber City, Utah, at the doorstep of some of the best riding this side of… anywhere. 

 

No matter the build, any bike we send out into the world is first built, checked, and thoroughly tuned by a professional mechanic. With a bill of good health, it’s then repackaged into a specially-made ride-ready box designed to transport the bike to the rider with as little disassembly as possible. In the end, all you need to do is attach the front wheel, insert the seat post, and dial in your fit.  

 

We’re here to help along the way. From picking your bike to support down the road, the Ventum customer support team is here for anything you need. 

VENTUM NS1 RED AXS FEATURES

A MODERN CLASSIC


We built the NS1 with the belief that you can have the perfect do-it-all road bike. 

You can race it, train on it, climb high, corner hard, and go long. It’ll do anything you want very, very well. It’s our expression of what every road bike should be. 

The bike is designed to be stiff, but compliant in all the right places; light, but still aerodynamic; aggressive, but forgiving. You’ll know it when you feel it, the NS1 is the perfect one-and-done road bike. 

 

STIFF, LIGHT, CONFIDENTLY QUICK

 

Our engineering team set out to strike a balance between weight, handling, stiffness, and aerodynamics; because, despite what some may tell you, the best bike is a game of balance.

 

We leaned on a collective decades of experience in designing carbon fiber bicycles to refine the NS1’s layup, strategically stiffening some areas while shaving weight and adding forgiveness elsewhere. The result is our expression of what a modern road bike should be — simple, fast, and well rounded.

TIRE CLEARANCE TO 700x35c 


The NS1 can accommodate tires up to 700x35c, giving you ample options for tires that are more aero, more forgiving, and more versatile. 

 

Among our pros, the NS1’s additional tire clearance has even made it a choice option for mixed-surface races like the Belgian Waffle Ride. Put a pair of file tread 35c tires on, and you’ve got a bike that’s light and nimble on pavement and more than capable on dirt.

Home Reviews 1

"Ironman Sweden was my first race on my new bike from Ventum, a Shimano Dura Ace 12-speed. The aero comfort is easy to adjust to the perfect fit and with the fantastic disc brakes it is easy to keep a good rhythm through the corners. With the Ventum One, I achieved my fastest bike split at Ironman Sweden."

- Jesper Svensson

“There is nothing I would rather use to sail the gravel seas of eastern Nebraska than my GS1 (except for maybe a tandem). Its smooth comfort allowed me to carry my speed and momentum over the tops of every one of the endless rollers on the Gravel Worlds course. I was able to open gaps through the loose corners all day long, thanks to the bike’s stability and nimble handling, and there’s just no arguing with a 22 mph average speed over 150 miles, with 11,000 feet of elevation gain, on a course that’s 98% gravel, on my way to 2nd place out of a very talented pro field."

- John Borstelmann

"The GS1 is everything I want in a gravel bike. The combination of smooth cruising on pavement and steady rolling over rowdy terrain makes it the most dynamic bike. From champagne gravel to chunky single track, my GS1 has performed beautifully through it all. Let’s not forget that it has ample tire clearance and is aesthetically stunning!"

- Lindsey Stevenson
