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.

• Shimano 105 Di2 build: 8.65 kg
• Shimano Ultegra Di2 build: 7.8 kg
• 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.

No, you can't raise the handlebars after the bike is built, because the steerer tube is trimmed to the correct length during assembly. However, we include 20 mm of spacers, so you can lower the bars if needed, but you can't raise them further.

The ULTRA-RACE is equipped with fast, durable, and grippy 30mm road tyres and can accommodate up to 32 mm 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 CGR 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 either a SRAM-specific derailleur hanger or a Shimano hanger, depending on the fitted groupset.
