About The Ventum NS1 Carbon Shimano Dura-Ace Di2 Road Bike
The Ventum NS1 Carbon Shimano Dura-Ace Di2 is a full carbon fiber road bike built as an all-rounder — capable on long climbs, comfortable on long training days, and quick enough for race day. This third-generation NS1 uses a higher-modulus carbon layup that Ventum states cuts more than 200 grams versus the previous generation while adding frame stiffness. The front end has been reworked with an extended leading edge ahead of the steerer and a pronounced hourglass head tube, narrowing the frame's profile into the wind.
This build pairs the frame with a Shimano Dura-Ace Di2 2x12-speed electronic groupset, Shimano Dura-Ace hydraulic disc brakes, and Zipp 454 NSW carbon tubeless wheels with integrated TyreWiz. The Ventum CR2 one-piece carbon bar/stem keeps the front end clean with internal routing, and tire clearance up to 700x35c (700x30c stock) leaves room to size up for comfort or rougher roads without changing bikes.
Who It's For
- Riders who want one road bike for racing, structured training, and long days in the saddle, not a dedicated race-only frame
- Riders who want Shimano Dura-Ace Di2 electronic shifting and hydraulic disc braking
- Larger-frame riders who want a more accommodating reach and stack without softer handling
- Consider a different bike if you need gravel-level tire clearance beyond 700x35c, or prefer mechanical shifting
What to Look For
- Fit first: crank length, bar width, and stem length change by frame size, and the one-piece CR2 cockpit means a bar/stem change is a cockpit change
- Component tier: this build carries full Shimano Dura-Ace Di2 and Zipp 454 NSW wheels — confirm it matches the investment level you're targeting
- Terrain: stock 700x30c tires suit smooth pavement; riders planning rougher roads should note the 700x35c max clearance
Key Features
Frame and fork: The full carbon NS1 frame and fork use internal cable routing, a T47 threaded bottom bracket, flat mount disc brakes front and rear, and a UDH derailleur hanger. The threaded BB simplifies service versus press-fit systems, and the reworked front end — extended leading edge, hourglass head tube — is built to cut frontal area and drag.
Groupset: Shimano Dura-Ace Di2 2x12-speed electronic shifting runs 52/36T chainrings (170mm cranks XS–M/L, 172.5mm L–XL) and an 11-30T Dura-Ace cassette, pairing electronic shift precision with enough range for climbing.
Braking: Shimano Dura-Ace Di2 hydraulic disc brakes with Dura-Ace RT-MT900 Centerlock rotors (160mm front, 140mm rear) for consistent stopping power in mixed weather.
Wheels and tires: Zipp 454 NSW carbon tubeless wheels with integrated TyreWiz and stock Schwalbe One Performance RaceGuard tires (700x30c), with clearance to 700x35c for added comfort or puncture protection on rougher pavement.
Cockpit: The Ventum CR2 one-piece carbon bar/stem is sized per frame — width and length both scale with size — alongside a Ventum carbon seatpost (10mm offset) and Fizik Vento Argo R5 saddle (140mm). A computer mount is integrated; the computer is sold separately.
Rider Intent Summary
- Biggest strengths: full Shimano Dura-Ace Di2 groupset, Zipp 454 NSW carbon wheels, and a frame redesigned for less weight and drag
- Tradeoffs: the one-piece CR2 cockpit limits bar/stem adjustment after purchase, and the computer mount needs a separately purchased computer
- What makes it different: extended reach and stack (especially on larger sizes) widen the fit range without softening race geometry, and 700x35c clearance is generous for an aero-focused frame
Victory's Take
We'd point riders here when they want one road bike that handles race day and everyday training without a groupset or wheel upgrade — this Dura-Ace Di2 and Zipp 454 NSW spec is about as complete as an all-rounder build gets. At Victory Bicycle Studio, we still recommend a professional fit before ordering, since the CR2 cockpit's sizing is tied to frame size rather than independently adjustable.

Frequently Asked Questions
How is the bike packaged and how long does delivery take?
All bikes are securely packaged to ensure that damage doesn't occur during shipping. All parts of the bike are padded and if needed, zip tied to minimize or eliminate movement inside the box. Once a bike is handed to the shipping company (usually Fedex or UPS), depending on your location, delivery will range from 1 day to 8 days. If you do choose the option for Professional Assembly or White Glove Delivery, this can add anywhere from 2 days to 5 days to the lead time.
Can I finance the purchase of my new bike?
Yes. Simply select the Shop Pay Installments option which will allow you to buy now and pay later. Shop Pay Installments is powered by Affirm. If you would like to determine your spending limit, simply download the Shop app or the Affirm app on your smartphone and after you create an account on one of these apps, the app will let you know what is your spending limit.
Can I return the bike if it doesn't suit my needs?
Our return process is as follows. The customer is responsible for the return label ($150). Once the returned bike arrives at our warehouse, our team will inspect it and make sure it is in new condition and undamaged. Once we verify, we will process the return and issue a refund to the original payment method on file. To clarify the amount refunded, it would just be the amount of the bike (and tax if applicable) less the $150 shipping label that we provided, but the original shipping is not refunded. So if the original bike cost $4,500 and shipping was $150 (so you paid $4,650), you would be refunded $4,350 (the $4,500 less $150 for the return label) assuming the bike was returned in new and un-used condition and within the 30 day return period.
What does the warranty of my new bike or product cover and what is the warranty period?
Depending on the bike or any product, different companies have different warranty policies. If you do ever have an issue with your bike or any product, simply email us at online@victorybicyclestudio.com and we will assist with any warranty issues and clarify the warranty for the affected product.
Can I have my bike serviced at any bike shop?
Typically, to avoid any issues with your warranty, you should bring your bike to a certified mechanic or bike store for that bike (i.e. if you have a Trek bicycle, you should bring the bike to be serviced to a local bike store that is an authorized Trek dealer). If you need assistance, simply email us at online@victorybicyclestudio.com and we can direct you to a certified dealer of your bike.
Do you ship bikes internationally?
We unfortunately do not ship bikes outside of the 48 contiguous states of the United States. We do recommend for international customers to open (or use a current account) account with a freight forwarding company. If you use a freight forwarding company located in the U.S., make sure to put your billing address for a dedicated credit card as the same address as the freight forwarder so that you don't have any credit card or payment method issues).
Once you do this, simply place an order with us and we can ship to the U.S. address as long as the credit card doesn't get rejected. Once the freight forwarder has the box/order/shipment, you would instruct them to then ship to you in your home country and they would charge you their own shipping charge to ship to your international address.
Do you offer free shipping?
We do offer free shipping on non-bike orders over $100. We do not offer free shipping for bicycles unless it is a one time promotion. Generally, bike shipping will cost $150 and that covers just the shipping of the bike with no assembly. If you were to bring that bike to your local mechanic or bike store, you would pay them their assembly fee. If you choose our Professional Assembly option for $200, our service technicians would assemble the bike before shipping and then re-pack the bike safely for transit. When you receive the bike you would attach the front wheel, attach the seatpost/saddle, and raise the handlebars and clamp them. Those three items do have to be detached to minimize or eliminate the chance of damage in transit.
How much does shipping cost?
For orders of parts, accessories, apparel, etc. on orders under $100, shipping is a flat rate of $9.99. Regular bike shipping without assembly is $150, bike shipping with Professional Assembly is an additional $200 (so $350 in total which includes the $150 of regular shipping). Our White Glove Delivery option is $699 and that will cover the assembly of the bike and our White Glove Delivery partner delivering your dream bike to your front door, ready to ride!
How can I track my order?
When you place your online order, you will receive an instantaneous email update with your order number and order details, and shortly after, you will receive a follow up order email with the tracking number for your order. If you still need assistance with your order, feel free to email us at online@victorybicyclestudio.com and we will respond asap.
What happens if my package arrives damaged?
If your package arrives damaged, email online@victorybicyclestudio.com with pictures of all angles of the box and pictures of the damaged product and we will work with you to either send a new replacement asap and coordinate return (or re-imburse you for labor or costs incurred to fix the issue at your local bike store).
Are pedals included with the bike?
If you do not see pedals in the bullet point product specs on the product page, the bike does not come equipped with pedals. Many manufacturers do not spec bikes with pedals, so they are often purchased separately.
If I only pay the $150 for bike shipping, can I assemble the bike on my own?
Victory Bicycle Studio highly recommends that you bring your bike to your local certified bike store for the brand of the bike that you purchased. If you do attempt to assemble the bike and damage occurs, this may result in your warranty not being honored. For that reason, we do highly recommend to select our Professional Assembly option for $299.
