About Noah Fast 3.0
The Noah Fast is the third generation within our aero bike family. Icons such as Robbie McEwen, André Greipel, and Caleb Ewan won Tour stages on its predecessors. Built upon this legacy, the Noah Fast is 8.5 watts faster than its predecessor at a speed of 50 kilometers per hour.
The Noah Fast represents minimal aerodynamic drag, a modern geometry that allows for aggressive positioning, a new aero cockpit, and a holistic approach focused on ultimate efficiency. It is the official bike of the Uno-X Mobility men’s and women’s teams.
Tested and approved by Uno-X Mobility.
We develop our bikes in consultation with the professional cyclists of Uno-X Mobility. They provide feedback during the development process so that we can further optimize our bikes. For us, the quality label that the bikes are tested and approved by the professionals at the highest level is essential. The result of this collaboration? Victory in the Omloop Nieuwsblad and the team’s very first stage win in the Tour in 2025.
Cockpit Integration
The Nimbus Aero cockpit follows the trend in the peloton towards narrower handlebars (360 center-center) with flared drops (400 center-center). The top of the handlebar has a slight backsweep for an ergonomic position. The drops of the handlebar allow a aero position of the shifters, while being UCI compliant.
The Nimbus Aero cockpit was specifically developed for this new model and was an integral part of the frame's development process
Progressive racing geometry
A steeper seat angle aligns with the changing preference of riders towards a position with an open hip angle for a better power transfer.
A lowered bottom bracket compensates for the wider tires used in modern cycling.
Finally, the lower head tube with integrated cockpit allows the rider to have a more aggressive aero position, resulting in a reduced frontal area.
Pushing the limits of UCI regulations
The new Noah Fast has been fully developed based on the latest UCI regulations regarding tube shapes and profiles. The main difference is the use of the 8:1 rule, which allows tubes to be eight times longer than their width, whereas previously it was 3:1. The result is long, narrow profiles in the fork and seat stays.
Universal Derailleur Hanger (UDH)
The universal derailleur hanger (UDH) is the new standard in the cycling world. Not only is this derailleur hanger compatible with all modern shifting groups, it also protects against derailleur breakage and chain drops. In mountain biking, UDH has long been very common, and Ridley is bringing the technology to other segments as well.
Removable front derailleur clamp
Our innovative removable front derailleur clamp ensures a sleek, streamlined appearance when using a 1x setup. In collaboration with Wolf Tooth, we’ve developed a custom chainguide and chain catcher perfectly tailored to fit our frames. To maintain a clean and polished look, we’ve also designed a specialized cover to seamlessly replace the clamp when it’s not in use.
Holistic approach to aerodynamics
The new Noah Fast is not merely a lightning-fast bike but a 100% ‘performance package’ that approaches cycling from a 360-degree perspective. Every aspect of the bike is adapted to modern cycling. The cockpit dimensions and frame geometry are tailored to the expectations of professional riders. The tire clearance of 34mm will allow even use the Noah Fast on rough terrain like Paris-Roubaix. The developers carried out all simulations with the bike as a whole. That means: including wheels, water bottles, bike computer, and all other essentials. They did these tests under difference wind angles to simulate the performance in the real world . After all, this is how riders actually use the Noah Fast.
Dealer Service

Help & support
How can we help?
Which seatpostclamp is used
The integrated seatpost clamp (Ridley article code SPCAER4ZA007) is designed for the aero seatpost of the Noah Fast and Noah.
What are the different cockpit options?
We have developped a specific aero integrated cockpit for the Noah Fast. The cockpit has different stem lengths and a width at the shifters of 360mm center-center and 400mm center-center in the drops for an optimised aero position. To find your perfect position we introduce also 3 different stem stack options (55, 75 and 100mm). This allows you to ride with less or without stemspacers and find your perfect position on the bike.
What frame size do i need?
The Noah Fast / Noah uses a progressive performance geometry. This means we use a steeper seat tube angle to have a more central position on the bike. To find your frame size, you should compare the actual toptube length of your current bike and compare it with the Noah (Fast) instead of using the "reach" number in the geometry chart. For a detailed bike fit, we advice to contact your local dealer.
What is the maximum torque for the seatpost clamp?
The maximum torque to fix the seatpost clamp is 10Nm, like mentionned on the clamp
Which headset type is used?
The frame uses a 1 1/8" upper bearing (IS42/28.6 45°/45°) and 1 1/2" lower bearing (IS52/40 45°/45°)
What is the tire clearance?
The tire cleance of the Falcn RS is 34mm, actual width. This means the actual width of the tire on the rim. This can be different from the size mentionned on the tire.
Can I use a mecanical groupset?
No the frame is only compatible with electronic groupsets of Shimano and Sram.
What BB standard is used?
We use a BB86 press-fit bottom bracket standard on the Fenix SLiC, Fenix Disc, Kanzo Adventure, Kanzo Fast, Grifn, Falcn RS, Falcn, Noah Fast and Noah
What hanger is used on the bike?
The uses the SRAM Universal Derailleur Hanger (UDH). This means you will find easily a replacement hanger wherever you are as it is a standardised hanger (Ridley article code HANUDHSRA001)
What TA is used on the bike?
The frame needs a 12mm TA with a thread of 1mm (Ridley article code QRET124ZA046)
Why is the turnin radius limited on the Noah Fast and Noah?
We have added a rotation stopper in frame bearing cover interface. This rotation stopper will protect your frame from the impact of the cockpit in case of a crash.
What’s makes the geometry of the Noah Fast progressive?
The Noah (Fast) has a steeper seattube angle of 75° in size M, compared to 73° on the previous Noah (Fast). This steeper seattube angle follows the latest trend we see in profesionnal cycling where riders want to ride in a more forward position on the bike, closer to the bottom bracket. This position allows the rider to push in a more efficient way on the pedals by a more open hip angle. From a geometry perspective, we have kept the actual top tube length the same, compared to the previous Noah so the distance between the saddle and cockpit remains the same.
Why is the frame reach of the Noah (Fast) longer then the previous Noah (Fast)?
The Noah (Fast) has a steeper seat tube angle (75° in size M vs 73°) compared to the previous Noah (Fast), but the same actual top tube length. The result of this steeper seat tube angle is that the reach number will increase as a bigger part of the actual top tube length will be in front of the bottombracket and a smaller part behind the bottom bracket. When comparing the sizing of the Noah (Fast) to other bikes, use the actual top tube length as a reference number to define your frame size.
What’s the stem reach and stem stack of the Nimbus Aero?
With the development of the Nimbus Aero cockpit, we have introduced 2 new definitions for measuring our cockpits:
- Stem reach: this is the actual reach that the cockpit will add to your frame reach, measured from the center of the steerer to the center of the handlebar, in a horizontal way.
- Stem stack: this is the stack that the cockpit will add to the stack of the frame. We have 3 different stem stack options: 55, 75 and 100mm. This allows us to keep a neat, aero integration of the cockpit without adding too much spacers under cockpit. There is still the option to add 20mm spacers under the cockpit to finetune your position.
- On our stock bikes, we are using the 75mm stem stack option of the cockpit. In the configurator there is the option to select the other options.
How can I find my perfect position on the Noah Fast?
The new cockpit definitions of stem stack and stem reach will help you to find the perfect position on the bike.
- Total reach of the bike: distance of the nose of the saddle behind the bottom bracket + frame reach + stem reach.
- Total stack of the bike: frame stack + spacers + stem stack
