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
If you're between sizes, we generally recommend choosing the smaller option. It's easier to fine-tune the fit of a smaller frame by raising the seat post or using a longer stem, whereas a larger frame leaves much less room for adjustment.
Build weights are provided for a medium‑sized frame and are intended solely as general guidance. Actual weight will vary based on the selected components and accessories, as well as standard manufacturing tolerances. These figures do not constitute a guarantee or warranty of final product weight, and we may occasionally make minor modifications to specifications without prior notice.
- Dura-Ace Di2 build: 7.0 kg
- SRAM Red AXS build: 7.0 kg
- Ultegra Di2 build: 7.7 kg
- Force AXS build: 7.9 kg
- 105 Di2 build: 8.3 kg
- A SRAM Red AXS build with Scope Artech wheels and a medium frame weighs 6.58kg.
- Frame only (medium): 775 g
We offer a lifetime warranty on all Ribble frames and forks for the original purchaser. This covers any manufacturing defects in materials or workmanship so you can ride with complete confidence. The standard manufacturer's warranty covers all other components.
Yes, the ULTRA-RACE has received accreditation to be race-legal for UCI-sanctioned events.
Yes, enhanced cable integration offers a neat, cable-free appearance by keeping cables hidden, shielded from wind, and protected against the elements.
No, the handlebars can't be raised after the bike has been built, as the steerer tube is trimmed to the correct length during assembly. However, we include 20mm of spacers, so you can lower the bars if needed, but raising them further won't be possible.
The ULTRA-RACE is equipped with fast, durable, and grippy 30mm road tyres and can accommodate up to 32mm tyres.
No. Ribble bikes are supplied with inner tubes installed as standard, even when fitted with tubeless-ready wheels and tyres.
If you'd like to run a tubeless setup, the conversion must be carried out after delivery. This typically requires tubeless valves, sealant and, in some cases, tubeless rim tape depending on the wheel specification. We recommend following the wheel and tyre manufacturer's instructions when converting to tubeless.
This approach gives riders the flexibility to choose the setup that best suits their riding preferences and maintenance requirements.
No, the ULTRA-RACE is designed as a pure racing bike. For pannier rack compatibility, please explore the ALLROAD collection.
The ULTRA-RACE isn’t designed for traditional full-length mudguards. But it may be compatible with clip-on mudguards that attach to the seat stays and forks, for lighter, removable protection.
The ULTRA-RACE features two bottle mounts on the seat and down tubes. It is designed to be faster with bottles fitted than without. Pair it with Ribble Aero Bottle Cages to maximise aero gains.
It's designed to accept a 68mm BSA threaded bottom bracket.
No, the ULTRA-RACE uses a proprietary D-shaped carbon seatpost, making it incompatible with third-party brands.
The ULTRA-RACE uses a Shimano-specific derailleur hanger.
Yes, we recommend a maximum system weight of 120kg (bike, rider & luggage)
No, our bikes don't have pedals as standard to accommodate the wide range of pedal and shoe preferences. However, you can easily add your preferred option from our best-selling pedal selection during the bike configuration process.
