Description
We have crafted a World Tour-worthy bike using a carefully curated selection of top-tier components, ready to compete at the highest level. In range-topping Hero specification, the ULTRA-AERO SL R features Shimano's professional-grade Dura-Ace Di2 groupset, Zipp 303 SW aerodynamic carbon wheels, World Tour favourite Pirelli P-Zero Race tyres, and 3D-printed Selle Italia SLR Boost Carbonio Superflow saddle. The integrated aerodynamic carbon cockpit completes the ultimate performance package.

Groupset
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. Featuring semi-compact 52/36 gearing for the perfect balance of top-end speed and climbing agility, every component is refined to deliver the ultimate on-bike experience, whether you’re sprinting to victory on the Champs-Elysees or crushing your local climb.


Wheelset
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 black tyres and 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.


Handlebars
Engineered for pure speed, the ULTRA-AERO bars are purpose-built for our fastest-ever aero bike. Their patented, next-generation design introduces a revolutionary wake-generating concept that reshapes airflow, creating a controlled pocket for the rider’s legs to sit within and reducing drag where it matters most. The aggressive, wing-shaped tops slice the air with scalpel-like precision, while the ergonomic drops and flat-top section deliver comfort and control on long rides or steep climbs. A textured finish removes the need for bar tape, keeping things clean, fast, and uncompromisingly aerodynamic.


Saddle
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
