Integration and compatibility

As the first bike to maximize the potential of the UCI’s revised design rules, the HANZŌ uses never before applied airfoil sections for the full 16cm of length allowed by the alignment of the head tube and down tube boxes. The design also integrates the basebar and frame top tube into an aero section, with seamless blends between those shapes to ensure minimal airflow detachment. Cable and brake line integration also plays a key role to ensure the HANZŌ shows the most aero face to the wind as possible.

With a basebar and mast specifically designed to accommodate the aero extension bars from a wide range of popular manufacturers, the HANZŌ is the ultimate time trial or triathlon bike for anyone looking to get the most out of themselves and their equipment.

A stiff, responsive ride

Aero isn’t everything. The HANZŌ is so much more than one of the world’s fastest time trial bikes. It’s incredibly stiff as well, capable of translating each pedal stroke into speed. Though the front end of the HANZŌ focuses on aero, the one piece fork and head tube leading up to the mono riser ensure the front end is rigid and immediately responds to the rider’s input.

As we move further back on the bike, where measurable aero advantages are less prominent, the stiffness of the design takes center stage. The down tube has an aerodynamic function, particularly in how well it integrates an aero water bottle, but it also offers a sturdy joining point for the super rigid bottom bracket. That junction point is not only exceptionally aero, but extremely stiff, as well. This design pushes the UCI rules right to the limit for the ultimate in aero performance while still being able to transfer power efficiently.

Though we enhanced the aero qualities of the rear triangle wherever possible, like using the width of the seatstays to smooth the airflow coming off the rider’s legs, the crux of the back end is its rigidity. We’ve also been careful to ensure practicality, with features like a seatpost that fits a Di2 battery.
