Ultra-Aero SL R – HeroShimano Dura-Ace Di2

The pinnacle of Shimano Road technology and innovation. Dura-Ace 9200 brings new levels of comfort and control to road cycling. With the fastest wireless shifting and even more precise brake modulation, Dura-Ace redefines performance. Wireless 12-speed shifting keeps your bike looking clean while offering the fastest, most precise gear changes available. Speed is the driving force behind Dura-Ace 9200, with every component refined to provide the best on-bike experience, whether you’re sprinting to victory on the Champs-Elysees or crushing your local climb.

Zipp 303 SW is the new go-to wheelset for all roads ahead, with SRAM AXS-connected in-wheel tyre pressure monitoring. Lightweight yet strong and resilient, 303 SW delivers aerodynamic performance and superior speed, no matter the surface or terrain. Paired with a Pirelli P-Zero Race tyre designed to deliver high-performance results. Puncture-resistant without impacting weight and able to maintain grip in wet or dry conditions, this is the tyre of choice for the pro peloton.

This bike is fitted with standard butyl inner tubes. As a result, the tyre pressure monitoring system built into the Zipp 303 wheelset will not be active. To enable this feature, Zipp AXS smart tubes or a tubeless setup with Zipp’s compatible valves are required.

Engineered exclusively for our fastest-ever aero bike, the ULTRA-AERO bars redefine aerodynamic integration with a patent-pending, next-generation design. At the heart of this innovation is a groundbreaking wake-generating concept that disrupts airflow, creating a controlled wake for the rider’s legs to sit within while strategically manipulating vortexes to enhance overall aerodynamics. The aggressive, drag-defying anatomic wing top section reinforces the bar’s aero dominance, cutting through the air with precision. But speed isn’t the only priority—comfort is integral to the design. The flat-top section offers a secure and relaxed hand position for climbing, while the ergonomically optimized drops naturally conform to the rider’s palm. With a textured finish that eliminates the need for bar tape, every detail is fine-tuned for performance and control.

The ULTRA-AERO seat post features a truncated aerofoil profile that is aerodynamically optimised to reduce drag in the high-speed airflow disturbed by the rider’s leg. A composite shaft absorbs road shocks for vibration-smoothing ride quality, further enhanced by a Selle Italia SLR Boost 3D Kit Carbonio Superflow saddle, featuring a 3D-printed surface designed to maximise comfort and performance and a superflow cut-out for increased flexibility and airflow
