Ventum Tempus Ultegra Di2 Carbon TT Bike
Ventum Bikes Will be arriving December 2025
To put it simply, the Tempus is Ventum's fastest and most competitive TT and Triathlon bike yet. Engineered over thousands of hours, rooted in a decade of feedback from some of the best athletes in the world, and proven in real-world testing, it’s the bike you want for days when going excruciatingly fast is the only priority for when you’re driven to not just beat your personal best, but also everybody else.
Tip to tail, the surface of the Tempus has been engineered with airflow in mind. Beginning at the head tube, functional airfoils taper backward the full length of the frame, working together to strategically smooth and direct air as it passes over rider and bike. Combined with its uniquely wide-set fork and seat stays that channel clean air around some of the more problematically turbulent areas, the entire bike is engineered with one goal in mind: Make clean air.
Thousands of hours of engineering, rigorous CFD analysis, and iterative wind tunnel testing fuelled the design of the Tempus, and that design has been proven in the real world. Benchmarked against its predecessor, the Ventum One Disc, the Tempus tests up to 15 watts faster in certain conditions and configurations.
Though the aerodynamic arms race among bike companies is what grabs the most attention, a fast bike is a balance between aerodynamics, handling, and functional design. Races are won on real roads; with hills, curves, and a whole host of other terrain to navigate. We didn’t forget this.
Fast on paper must be fast in the real world. Ventum's engineers leaned on collective decades of experience to carefully build a bike that is lighter, simpler, and livelier than its predecessor. Ventum gave the Tempus an aggressively steep seat tube angle to place the rider more forward and on top of the pedals and stiffened the front end to give the bike scalpel-like precision in corners. Most notably, though, the Tempus is very light. Ventum's careful attention to carbon layup and mission of simplicity stripped the fat from the frame.
Light, efficient, and simple. Ventum wanted to push the envelope of aerodynamic efficiency without sacrificing real-world ride quality. Incredibly aero, but also snappy in corners and stable in crosswinds, the Tempus is made to inspire confidence anywhere from the windswept lava fields of Kona to the mountains of Nice.
Wide Is The New Narrow
Jutting far outboard of the frame, the Tempus' wide-set fork and equally wide seat stays are designed for one purpose: To create clean air. The wide fork channels clean air past the front wheel and onto the rider's legs, avoiding turbulence caused by the wheel and creating a shrouding effect over one of the most aerodynamically problematic body parts. Just behind the legs, airfoils on the wide seat stays not only direct air from the back of the legs over and around the wheel, but also help shroud the rear wheel at higher yaw angles.
Fast Should Feel Fast
Aerodynamic optimization can only take you so far. A fast bike is a balance between aerodynamics, handling, and functional design. An aggressively steep seat tube angle and strategic stiffening of the front end means the Tempus feels as fast as it looks on paper. It's also wickedly light, which helps make the bike feel more lively and responsive. Feedback from pros says we nailed it: They've raved about the Tempus' nimble yet stable handling.
Ultra-Adjustable Front End
Ventum partnered with Profile Design to engineer the Tempus in tandem with their all-new Wing Ultimate S base bar. Uncomplicated, incredibly aero, and extensively adjustable, the Profile Design cockpit systems gives riders and bike fitters the power to precisely dial in the front end position. Equipped with the 52 ASC aerobar extension, riders also have the option to upgrade their cockpit to the semi-custom ASC Pro extensions.
