This is a no-holds-barred triathlon machine—no restrictions, no limitations. The CADEX Tri frameset is designed, engineered and put to the test by the world’s fastest triathletes in a bold quest to push the sport forward. Created in conjunction with Ironman World Champion Kristian Blummenfelt’s attempt to break the seven-hour mark for the Ironman distance, a project dubbed Sub7, it features a radical monocoque frame, wide-spread fork legs and horizontal seatstays. The massive down tube doubles as a race-ready storage system, making hydration and nutrition easily accessible. And its wide-ranging adjustability makes it quick and easy to dial in over 1,000 fit configurations for personalized performance.

The CADEX Tri frameset makes it easier for athletes of all heights and body dimensions to achieve a perfect fit. Using real-world dimensional as well as stack and height data collected from pro and amateur triathletes, CADEX created five frame sizes and then configured ways for any rider, no matter what frame size they choose, to easily adjust critical fit factors.


Aero performance goes beyond wind-tunnel data. Using AeroSystem Shaping Technology to create a radical wide-spread, bladed fork, horizontal seatstays and other drag-reducing frame features—along with optimal rider position for Ironman racing—CADEX Tri is about achievable real-world gains.


The unique chassis of the CADEX Tri frameset—a massive down tube with no top tube—offers a complete hydration, nutrition and tool storage solution fully integrated into the frame. This design lets riders hydrate and refuel quickly and conveniently from the seated aero riding position while remaining totally self-sufficient on the course.


Engineered with the highest grade T1000 carbon fiber and cutting-edge layup techniques, the CADEX Tri frameset boasts class-leading pedaling and torsional stiffness with a total weight of just 4577 grams. Combined with ultra-adaptable fit, groundbreaking endurance aero technology, and a completely integrated hydration and nutrition system, the result is zero watts wasted.


The CADEX Tri frameset minimizes the amount of disassembly and reassembly needed and comes with a purpose-built, high-impact resistant Topeak travel case featuring airport-friendly wheels, a full interior protection system and built-in work stand.
