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. This uncompromising race machine pairs the precision of Shimano’s 105 Di2 electronic groupset with lightweight Ksyrium 30 wheels, Pirelli P Zero tyres for race-ready grip, and a unisex Selle Italia Model X saddle. A sleek, one-piece carbon cockpit adds aero efficiency where it counts most.
Groupset
Combining technologies and functions inherited from Dura-Ace, 105 Di2 will transform your cycling experience. With a shared Di2 platform, sophisticated ergonomics, 105-optimised gear ratios and the exceptional stopping power of hydraulic disc brakes, 105 Di2 marks a new era of affordable performance. Di2 gives you the instant and lightning-fast gear shifts of the world’s fastest semi-wireless groupset. With Di2 you are in complete control.
Wheelset
Ksyrium 30 Disc is the perfect entry point into high-level race performance. This tubeless-compatible wheelset's dynamic ride quality helps you roll faster and smoother while retaining a lightweight feel for climbing and accelerating. Paired with Pirelli P Zero road tyres; which balance performance with durability, for both reliability and comfort. The carcass features excellent puncture resistance, whilst coming in at an impressively low weight.
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 seatpost adds targeted flex to absorb 'road buzz', smoothing out rough surfaces and keeping you fresher for longer. It’s paired with the unisex Selle Italia Model X saddle—designed for both sustainability and performance. Featuring a glue-less assembly, gel padding, and a Superflow cutout, the Model X delivers all-day comfort without compromise.

FAQs
Ultra-Race 105 Di2Reviews
Based on 5 reviews
Spent three months chasing a mystery creak that turned out to be a poorly faced bottom bracket shell from the factory. Hugely frustrating experience.
Weekend rider · <20 km/week
Good bike for the money but the stock wheels and tyres are a letdown. Upgraded both and it transformed the ride. Frame and groupset are great.
Daily rider · 100 km+/week
My first serious road bike and it has not disappointed. The climbing ability surprised me on sportives. Only wish it came with better wheels.
Daily rider · 50-100 km/week
Incredible entry point to electronic shifting. The 105 Di2 is smooth and reliable. Frame is the same as the top builds — absolute bargain.
Weekend rider · 20-50 km/week
Disappointing finish quality for the price. Paint chips appeared within the first month.
