Ridley has updated its aero platform with the Noah Fast 3.0, the third generation of the Noah Fast. Ridley claims it is 8.5 watts faster than its predecessor at 50 km/h (manufacturer figures). This version is also presented as the bike used by the Uno-X Mobility men’s and women’s teams.

Aerodynamics: a frame designed at the limits of UCI rules

Ridley emphasises a holistic approach to aerodynamics (frame shapes, cockpit, rider position). The brand presents the Noah Fast 3.0 as developed to achieve minimal air resistance while remaining UCI-legal.

Progressive geometry: a more forward position on the bike

The Noah Fast 3.0 adopts what Ridley calls a progressive race geometry, notably with a steeper seat tube angle (example cited by Ridley: 75° in size M versus 73° on the previous generation). The goal is to place the rider more centred/forward and enable a more efficient pedalling position, while keeping an “effective” top-tube length comparable to the previous generation.

Ridley recommends comparing the top tube length between your current bike and the Noah (Fast), rather than relying solely on the reach value.

Nimbus Aero integrated cockpit: width and stack heights to choose from

The Noah Fast 3.0 receives a purpose-built aero integrated cockpit. Ridley states:

• Hoods width: 360 mm (centre-to-centre)
• Drop width: 400 mm (centre-to-centre)
• Three stem stack options: 55 / 75 / 100 mm, with the possibility of adding up to 20 mm of spacers to fine-tune the position (manufacturer information)

The brand also mentions a steering stop/limiter at the headset, designed to reduce cockpit-to-frame impact in the event of a crash.

Claimed standards and technical details

• Derailleur hanger: UDH (SRAM Universal Derailleur Hanger), said to be easier to replace thanks to standardisation
• Bottom bracket: BB86 press-fit (standard used on several Ridley frames cited by the brand)
• Headset: upper bearing IS42/28.6 (45°/45°) and lower IS52/40 (45°/45°)
• Thru-axle: 12 mm, 1 mm thread pitch (according to Ridley)
• Seatpost clamp: integrated system (maximum torque claimed 10 Nm)

Geometry chart (excerpt of the provided values)

Ridley publishes a size-by-size chart (XXS to L). For reference, for example:

• Seat tube angle (E): from 76.5° (XXS) to 74.5° (L)
• Head tube angle (F): from 71.5° (XXS) to 73.5° (M/L)
• Chainstays (G): 407 mm across all listed sizes

To choose the right size, Ridley also recommends comparing top tube and, ideally, getting professional advice (bike fit / dealer).

What it means for road use… and for gravel riders

The Noah Fast 3.0 is clearly an aero road bike (priority on efficiency at high speed, integrated cockpit, race-oriented geometry). For a Gravelpassion reader, it can make sense as a performance road bike alongside a gravel bike, especially if the goal is to ride fast in a group, tackle rolling sportives, or do rides where aero and position are paramount.

Conversely, those looking for a more versatile bike (luggage, rougher terrain, long-distance comfort, simple adjustments) will more naturally turn toward an endurance or gravel platform.

Our view

The Noah Fast 3.0 fits the current trend of “modern” aero bikes: deep integration, a more forward position via steeper seat tube angles, and narrow cockpits to optimise how the bike cuts through the air. That aligns with what we see at most major brands in the performance segment.

Keep in mind before you pull the trigger: integration and proprietary cockpits can complicate position adjustment (and sometimes maintenance), and the stated electronic-only compatibility shuts the door on mechanical builds. At this price (7,999 € with Force AXS), the key question becomes less “is it fast?” than “is it the right platform for your use and your position”, ideally validated by a bike fit or a test ride.
