Ridley Noah Fast 3.0 Frameset
Ridley Noah Fast 3.0 Frameset Info
There's a specific type of rider who should be looking at the Ridley Noah Fast 3.0 Frameset: someone who already owns a high-end electronic groupset worth building around, wants to choose their own wheels, and has no interest in paying for a complete bike's drivetrain just to pull it apart before the first ride. For that rider, this frameset is the right way into the Noah Fast line — Ridley's fastest road platform, sold as a frame, fork, and full Nimbus Aero Cockpit, ready to spec exactly as you want it.
The frame is Ultra HM Carbon, Ridley's Elite Series high-modulus layup, and the engineering behind it reflects a real generational step rather than a revision. Working within the UCI's updated 8:1 tube profile rule — which permits cross-sections up to eight times their width, compared to the previous 3:1 limit — Ridley shaped the fork legs and seat stays into long, narrow profiles that carry significantly less aerodynamic drag than older designs allowed. The claimed result is 8.5 watts faster than the previous Noah Fast at 50 kilometers per hour. Those numbers come from wind tunnel and CFD simulations conducted with the complete bike as a system — wheels, bottles, computer — at multiple yaw angles, so the advantage reflects real-world riding rather than idealized head-on airflow. The Noah Fast 3.0 is the official race platform for the Uno-X Mobility men's and women's professional teams, having carried the squad to victory at Omloop Het Nieuwsblad and their first Tour de France stage win in 2025.
The geometry follows where professional road racing has moved. Size M runs a 75° seat tube angle — two degrees steeper than the previous generation — pushing the rider further forward over the pedals for a more open hip angle and more efficient power transfer on hard efforts. The bottom bracket drops lower than before, accounting for the wider tires that are now standard across road racing. The head tube is short and designed to work as a unified system with the integrated Nimbus Aero Cockpit.
That cockpit is worth emphasizing. Ridley developed the Nimbus Aero specifically for the Noah Fast 3.0 and included it in the aerodynamic simulation process from the start — it's not an accessory that was bolted on at the end, it's part of what makes the frame fast. It ships with the frameset because Ridley considers it part of the aero package. The Nimbus Aero runs 360mm center-to-center at the hoods, flaring to 400mm at the drops, with 75mm bar reach and 125mm drop. Three stem stack heights are available — 55, 75, and 100mm — letting you find your position cleanly without relying on a column of spacers under the bar. The 5° flare gives the drops a slightly wider, more stable feel in an aggressive position.
Two things to know before you build: the frame is electronic-only — compatible with Shimano Di2 and SRAM eTAP AXS 12-speed, no mechanical option. And if you're planning a 1x build, the frame's front derailleur mount is removable. Ridley developed this with Wolf Tooth, along with a custom chainguide and chain catcher, and includes a cover plate that replaces the clamp when it's not in use — so a single-chainring build looks intentionally finished rather than like something was left off.

Design Benefits
- UCI 8:1 tube profiling: Long, narrow fork legs and seat stays enabled by the updated UCI rule deliver measurably lower aerodynamic drag — the direct source of the 8.5-watt gain over the previous generation at race speed.
- Nimbus Aero Cockpit included: Developed as part of the frame's aerodynamic system, not as an add-on. Getting the cockpit in the box means the front end and frame work together as Ridley intended — no compatibility questions, no separate purchase required.
- Progressive race geometry: The steeper seat tube angle positions the rider for better power transfer; the lowered BB improves stability with modern tire widths; the short head tube combined with the Nimbus cockpit enables a genuinely aggressive aero position.
- Removable FD clamp + UDH: The Wolf Tooth-developed removable front derailleur mount keeps 1x builds looking clean. The SRAM Universal Derailleur Hanger provides broad drivetrain compatibility and crash protection — and is easy to replace anywhere in the world.
- 34mm tire clearance: Room for 28–32mm tires at race pressures, with flexibility well beyond the old 25mm road standard. Useful for anything from smooth criterium courses to the rougher roads of spring classics riding.
Final Take
The Noah Fast 3.0 Frameset is the right choice when you know what you want to build and you're not willing to compromise on the frame underneath it. You're getting the same Ultra HM Carbon platform and Nimbus Aero Cockpit as the complete bikes — the parts that define how this machine performs — with full control over drivetrain and wheel selection. A UCI-legal race frame, built your way.
