Unrivaled: the bikes behind Kristian Blummenfelt’s historic year


Now, looking back on a historic season that included an Olympic gold medal, a triathlon World Championship victory and a dominant victory in his first Ironman distance race, it’s clear that all the preparation and hard work went into it. paid off for the 27-year-old Norwegian.

In addition to a focused training program that got Blummenfelt to start the year on a high note with several wins ahead of the Olympics, he has also added two secret weapons to his arsenal this year: his Propel Advanced SL Disc. for Olympic distance races; and its Trinity Advanced Pro for Ironman distance races.

Both bikes feature composite frames handcrafted by Giant with custom graphics made especially for Blummenfelt. Both also rely on integrated aerodynamics, in particular Giant’s AeroSystem Shaping technology, which uses CFD analysis and dynamic wind tunnel testing to optimize aerodynamic performance at all yaw angles.

Here’s a detailed look at the two machines Blummenfelt used to make 2021 a year to remember.


Blummenfelt’s choice for Olympic distance and sprint triathlons is the Propel Advanced SL Disc. It was the bike he used for the biggest race of his life at the Tokyo Olympics. Having already won several races before the Olympics, including the opening match of the triathlon world championship series in Yokohama and a triathlon world cup in Portugal, he arrived at the Olympics with supreme confidence.

The Propel Advanced SL Disc does double duty as a high performance aero road machine. It is designed to give solo runners all the advantages against the wind, whether they’re sprinting, attacking head-on, or trying to win an Olympic triathlon. It’s designed with Giant’s most premium frame material, the Advanced SL Composite. Its AeroSystem Shaping technology means that every tube shape and angle is optimized for minimal drag and designed to perform as a system in real road conditions.

The design of the Propel chassis is the result of extensive studies of computational fluid dynamics and dynamic wind tunnel testing. The tubes feature a truncated ellipse shape which, combined with the CADEX wheels and Contact SLR Aero cockpit, minimizes drag at different yaw angles for a measurable aerodynamic advantage.

For draft-legal races, Blummenfelt typically chooses a CADEX road wheel system that combines a 65mm deep aero rear rim profile and the versatile 42 front wheel. His racing bike is fitted with a Shimano Dura electronic drivetrain. -Ace Di2 and disc brakes. The frame and fork are engineered for disc brake integration, delivering powerful stopping power and modulation for increased control in all conditions and in all weather. Front and rear thru axles help increase stiffness and improve overall handling.

The frame of Blummenfelt’s Olympic gold medalist bike features special graphics inspired by the shippo motif, a common design in Japanese art and fashion. The overlapping circles and shapes symbolize harmony and happiness, and the five colors combine to convey a sense of movement and speed in the pursuit of victory.


Having accomplished everything he set out to do in short distance triathlons, Blummenfelt wasted no time in focusing on something new. For the very first time, he would attempt a long distance triathlon. With just a few months to prepare, he started training with the Trinity Advanced Pro, a pure triathlon and TT machine that would require a different riding position to maximize aerodynamics and comfort over the entire 112 distance. miles.

Blummenfelt chose Cozumel, Mexico to make his Ironman debut, as part of a plan to scale up and target more long-distance events in 2022, including the Ironman World Championships in Kona. He got off to a quick start at the Ironman Cozumel, finishing the 2.4 mile swim in second, 2 seconds off the lead.

From there, Blummenfelt opened things up with a dominant ride on his new machine. Riding with a CADEX Aero WheelSystem and his Giant Rivet TT helmet, he blitzed the bike stage with a time of 4:02:40, by far the fastest split of the day. He then won the race in a dominant fashion, beating second-placed Swiss Ruedi Wild by more than 15 minutes.

In fact, Blummenfelt shocked the triathlon world by recording the fastest Ironman time of all time (7:21:12). The Professional Triathletes Organization then removed this world record due to a downdraft in the Cozumel swim, but there is no denying that Blummenfelt was completely dominant and he looks set to rewrite the record books in the Ironman arena. .

Earlier this month, Blummenfelt closed its season with another big win at CLASH Daytona, a middle distance event hosted at famous motorsports venue in Daytona, Florida. With a 90 mile bike stage spanning multiple laps on the highway, he once again rode his Trinity Advanced Pro with a CADEX Aero WheelSystem.

Clearly, Blummenfelt is comfortable on his new bike. Designed using dynamic wind tunnel testing, the Trinity Advanced Pro offers a proven aerodynamic advantage. Beyond its aerodynamic engineering, Blummenfelt’s Trinity Advanced Pro offers tri-specific integrations, including an integrated front hydration reservoir, top tube storage box, and a water bottle that helps improve aerodynamic performance. cycling on the road. It also offers a wide range of adjustments which allows athletes to fine-tune the fit for comfort and efficiency over the 112-mile Ironman bike distance.

Custom graphics feature a blue-black fade intended to express the movement, the flow of the rider in the water, and the slicing of the wind on the road. Brush strokes above the main colors add to the effect, and the design is transferred to the CADEX Aero WheelSystem. The wheels are also inscribed with Blummenfelt’s signature and the word by which he lives: “It hurts more to lose”

Now that his dream season is over, the Olympic champion is already preparing for 2022.

One thing’s for sure, it’s going to be a wild ride.
