Description

Every great race bike starts with the right foundation. The Ribble ULTRA-RACE Frameset gives you the freedom to create your ultimate race machine, built on a UCI-approved carbon platform engineered for explosive acceleration and razor-sharp handling.

Constructed from advanced MT65 carbon fibre, the lightweight 775 g frame combines race-tuned stiffness with aerodynamic efficiency, giving you the response you need to attack on the climbs and sprint for the line. Each detail is designed to turn your effort into forward momentum, with the precision and control to perform when every second counts.

Supplied with matching carbon forks and the Ribble AERO-ROAD integrated carbon cockpit, this frameset gives your dream build a clean, purposeful look. Pick your components and fine-tune your setup to create a race bike that fits the way you ride.

Your build. Your rules.

No Compromise Construction

Engineered for all-out race performance, the ULTRA-RACE combines advanced MT65 carbon fibre with aerodynamically optimised tube profiles to strike the perfect balance between low weight and stiffness. Weighing just 775 g, the UCI-approved frame is built to accelerate hard and respond instantly to every move you make. It's race-tuned geometry delivers precise handling and confidence through technical corners and fast descents, while aero shaping inherited from the ULTRA-AERO helps reduce drag so you can hold your speed for longer. Light on the climbs. Fast on the flats.

No Compromise Construction

AERO-ROAD Integrated Cockpit

Small details make a big difference when you’re chasing speed. The Ribble AERO-ROAD integrated carbon cockpit combines lightweight construction with aerodynamic efficiency, creating a streamlined front end that helps reduce drag. Its one-piece design integrates the handlebars and stem, with concealed cable routing for a clean, uncluttered profile that cuts through the wind.

Engineered for responsive handling and precise control, the AERO-ROAD cockpit complements the ULTRA-RACE’s race-tuned geometry, giving you the confidence to dive into corners and stay in control in a sprint.

Ultra-Aero SL Seatpost

Designed to balance race-ready stiffness with everyday ride comfort, the ULTRA-RACE carbon seatpost features a sleek D-shaped profile that complements the frame’s aero design. Its lightweight carbon construction helps absorb road vibrations, reducing fatigue and keeping you comfortable and in control when the pace lifts.

A secure twin-bolt saddle clamp allows precise adjustment of your riding position, giving you consistent support and efficient power transfer when you’re out of the saddle on a climb.The ULTRA-AERO seat post features a truncated aerofoil profile that's aerodynamically optimised to reduce drag in the high-speed airflow disturbed by the rider's leg. A composite shaft absorbs road shocks for a vibration-smoothing ride.
