Description
It doesn’t matter when you launch your attack. On a brutal climb, amidst the chaos of a breakaway, or carving through tight corners on a blistering descent, the UCI-approved ULTRA-RACE is built to deliver in every race situation. The featherlight 775g frame is constructed from next-generation MT65 carbon with zonal deployment for maximised stiffness and power transfer where it counts. Precision-engineered for peak performance, it pairs Shimano’s pro-level Ultegra Di2 electronic groupset with Vision SC45 carbon wheels, grippy Pirelli P Zero tyres, and a race-optimised Selle Italia SLR saddle. A one-piece carbon cockpit maximises aero efficiency and delivers the handling edge you need to reach the podium.
Groupset
Shimano's latest Ultegra drivetrain delivers next-level ergonomics, enhanced braking control, and the unmatched precision of Di2 electronic shifting. Experience the world’s fastest, most reliable wireless shifts and a wide gear range that keeps even the steepest climbs within reach. With Di2, every shift is instant, accurate, and effortless—putting you in total control.
Wheelset
The Vision SC45 carbon wheels feature a versatile design optimised for 28–32mm tubeless-ready tyres, delivering the ideal balance of speed and efficiency. Paired with Pirelli P Zero road tyres, they offer a winning combination of performance, durability, and comfort. The lightweight carcass provides outstanding puncture resistance without compromising ride quality.
Handlebars
Precision-engineered from high-grade carbon, the Ribble Aero integrated handlebars deliver race-ready stiffness with a streamlined aero profile that reduces drag and boosts efficiency. Contemporary styling meets performance with ergonomic shaping for all-day comfort and fully integrated cable routing for a clean, modern, cable-free finish.
Saddle
A narrow d-shaped carbon seat post introduces flex where it counts, helping to take the edge off the roughest surfaces for a smoother ride, leaving you feeling fresher for longer. Paired with a Selle Italia SLR Boost which brings high performance and comfort to any road ride or race event. The neutral shape allows complete freedom of movement without compromising pedaling efficiency or power output.

FAQs
Ultra-Race Ultegra Di2Reviews
Based on 5 reviews
Bottom bracket failed catastrophically on a group ride. Embarrassing and potentially dangerous. Quality control needs serious improvement.
Daily rider · 20-50 km/week
Headset developed a creak after 500 miles that I still cannot fix. The endurance geometry is fine but the finishing kit lets it down at this price.
Daily rider · 50-100 km/week
Solid mid-range build. Nothing wrong with it but nothing that makes you go wow either. Comfortable on longer rides once I changed the bar tape.
Weekend rider · 20-50 km/week
Best value in the range hands down. Ultegra Di2 is 95% of Dura-Ace at a fraction of the price. Climbs beautifully and descends with confidence.
Racer rider · 100 km+/week
Very comfortable on long rides. The only thing I'd change is the saddle — swapped it within the first week.
