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.

• SRAM Red AXS build: 7.0 kg

Yes, the ULTRA-RACE has received accreditation to be race-legal for UCI-sanctioned events.

Your bike comes with an SRAM AXS charger and two battery packs — one for the front derailleur and one for the rear. With SRAM’s latest updates, the charger doesn’t include a cable, but there’s no need to worry: any standard USB-C cable will do the job.

Yes, enhanced cable integration offers a neat, cable-free appearance by keeping cables hidden, shielded from wind, and protected against the elements.

The ULTRA-RACE is equipped with fast, durable, and grippy 30mm road tyres and can accommodate up to 32 mm tyres.

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 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.

No, the ULTRA-RACE uses a proprietary D-shaped carbon seatpost, making it incompatible with third-party brands.

The frame is designed to accept the latest flat mount disc brakes.

Thru Axles:
