About The Ventum Tempus Carbon Sram Red AXS Triathlon Bike
The Ventum Tempus Carbon SRAM Red AXS is a full carbon fiber triathlon and time trial bike built for one job: going as fast as possible over a fixed distance. Every surface, from the head tube's tapering airfoils to the wide-set fork and seat stays, is shaped to manage airflow around rider and machine. This top-tier build pairs Ventum's aero-focused frame with the SRAM Red AXS electronic drivetrain and ZIPP 858 NSW carbon wheels for a complete race-ready aero package.
What separates the Tempus from an aero road bike adapted for triathlon use is that it's purpose-built around the TT position. Ventum steepened the seat tube angle to move the rider forward and on top of the pedals, then stiffened the front end for more precise handling in corners and crosswinds. In benchmark testing against its predecessor, the Ventum One Disc, the Tempus measured up to 15 watts faster in certain conditions and configurations.
Who It's For
• Competitive triathletes and time trial racers who prioritize aerodynamic efficiency above all else
• Riders ready for a dedicated TT/tri position — the steep seat tube angle and aero cockpit call for a proper bike fit
• Racers who want a fully specced electronic groupset with an integrated power meter, not a piecemeal build
• Riders upgrading from an entry-level tri bike who are ready for race-tier wheels and drivetrain
• Anyone wanting a multi-purpose road or gravel bike should look elsewhere — this is a single-discipline race bike
What to Look For
• Fit first: the seat tube angle and Profile Design cockpit (A3A risers add 30mm of stack) allow adjustment, but a professional fit session is essential
• Wheel and tire compatibility: the ZIPP 858 NSW wheels are hookless with a 23mm internal width; stock tires are 700x28c with clearance to 700x30c
• Groupset tier: SRAM Red AXS is SRAM's top-tier electronic groupset, with wireless Blip shifters on both the base bar and extensions
Key Features
Frame and fork: Full carbon fiber construction with functional airfoils tapering back from the head tube, plus wide-set fork and seat stays that route turbulent air around the rider. Internal cable routing and a T47 threaded bottom bracket with UDH compatibility keep the front end clean and simplify future drivetrain upgrades.
Drivetrain and shifting: SRAM Red AXS delivers 2x12-speed electronic shifting with wireless Blip shifters on both the extensions and base bar, so riders can shift from the aero position or while sitting up. The SRAM Red crankset includes an integrated power meter, running 48/35T chainrings with a 10-36T cassette.
Braking: SRAM S900 hydraulic disc brakes with Centerlock rotors (160mm front, 140mm rear) mount via flat mount standard for consistent stopping power in any weather.
Wheels and tires: ZIPP 858 NSW carbon wheels bring an 80mm rim depth, built hookless and tubeless-ready with a 23mm internal width. Tire clearance to 700x30c gives racers room to size up from the stock Schwalbe One tires without sacrificing aero performance.
Cockpit: Profile Design Wing Ultimate S base bar and 52 ASC extensions define the aero position, with A3A risers adding 30mm of stack for a less extreme setup. Extensions can be upgraded to the Profile Design ASC Pro.
Rider Intent Summary
• Biggest strengths: An aerodynamic frame paired with SRAM Red AXS electronic shifting and ZIPP 858 NSW wheels for a complete aero package
• Tradeoffs: The aggressive TT position and single-discipline focus mean this isn't built for casual or multi-purpose riding
• What makes it different: Benchmarked up to 15 watts faster than its predecessor, with wireless Blip shifters at both the base bar and extensions
Victory's Take
At Victory Bicycle Studio, we see the Tempus as a bike for riders who've outgrown their first tri bike and are ready to race at the front of the field. We'd recommend a full fit session before finalizing your position — this frame's speed only pays off when the rider is dialed in.

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.
