Ridley Noah Fast 3.0 Ultegra Di2 Bike Info
The Ridley Noah has a history most aero road bikes can only aspire to. Robbie McEwen, André Greipel, and Caleb Ewan — three of the fastest sprinters professional cycling has ever produced — all won Tour de France stages on earlier generations of this Belgian-built machine. The Ridley Noah Fast 3.0 Ultegra Di2 Bike is the third evolution of that legacy, and it arrives with one stated ambition: to be the fastest road bike Ridley has ever built. According to Ridley's own wind tunnel data, it is 8.5 watts faster than its predecessor at 50 kilometers per hour. That advantage comes from a ground-up redesign, not incremental tweaks.
At the core of that redesign is Ridley's decision to fully exploit the UCI's updated 8:1 tube profile rule — a change that permits tube cross-sections to be eight times longer than their width, compared to the previous 3:1 limit. The result is a fork and rear triangle with long, knife-like profiles that slice through the air with far less resistance than was previously possible. But Ridley didn't stop at tube geometry. Every aerodynamic simulation was conducted with the complete bike as a system — wheels, water bottles, bike computer, all of it — under multiple wind angles to reflect how the Noah Fast 3.0 actually gets ridden. This holistic approach is what separates a genuinely fast bike from one that merely looks the part. The official race bike of the Uno-X Mobility men's and women's teams, the Noah Fast 3.0 has already proven itself at the highest level, helping the team to victory at Omloop Het Nieuwsblad and their first Tour de France stage win in 2025.
Geometry received equal attention. The seat tube angle on the Noah Fast 3.0 measures 75 degrees in size M — two degrees steeper than the previous generation — positioning the rider further forward over the bottom bracket. That shift opens the hip angle for more efficient power transfer on sustained efforts and brings the body into the kind of aggressive position that matters at race pace. The bottom bracket sits lower than before, accounting for the wider tires that have become standard in modern road racing. A shorter head tube combined with the integrated Nimbus Aero cockpit lets riders achieve a genuinely aero front-end position without stacking spacers to compensate for an ill-fitted frame.
This build pairs the Ultra HM Carbon frameset with Shimano Ultegra Di2 throughout — R8150 front and rear derailleurs, R8170 hydraulic disc brakes and shifters, and an R8100 crank running a 52/36 chainring setup with an 11-30 12-speed cassette. Electronic shifting is not just compatible here; it's required. The Noah Fast 3.0's cable routing and frame design are built exclusively for electronic groupsets. The wheels are DT Swiss ARC1400 Dicut, 65mm deep with 22mm internal width front and rear — a tubeless-ready deep-section carbon wheel that adds its own aerodynamic contribution to the system. Up front, a Continental Aero 111 handles airflow around the leading wheel. At the rear, a Continental GP5000S TR handles grip and rolling resistance. The Nimbus Aero cockpit — designed specifically for this frame as an integral part of its development — runs 360mm center-to-center at the hoods, flaring to 400mm at the drops, with 75mm bar reach and 125mm bar drop. Saddle duties fall to the Selle Italia SLR Advan L3.

Design Benefits
- UCI 8:1 tube profiling: Long, narrow fork legs and seat stays developed to the limit of current UCI rules produce measurably lower aerodynamic drag — a key contributor to the 8.5-watt gain over the previous Noah Fast at 50 km/h.
- System-level aerodynamics: Wind tunnel and CFD simulations were conducted with the complete bike — wheels, bottles, computer — at multiple yaw angles, so the aero advantage holds up in real-world riding conditions, not just head-on airflow.
- Progressive race geometry: A steeper seat tube angle improves power transfer; a lower bottom bracket accounts for wider tire profiles; a shorter head tube with integrated cockpit puts riders in a genuinely aggressive position without fit compromises.
- DT Swiss ARC1400 Dicut wheels: The 65mm deep-section carbon rims with 22mm internal width add their own aerodynamic profile to the system, and the tubeless-ready construction opens the door to lower pressures for improved grip and comfort on rougher roads.
- 34mm tire clearance: Enough room for contemporary race tires and wider rubber, giving riders flexibility across different road surfaces — including the kind of rough terrain seen at Paris-Roubaix.
Final Take
The Noah Fast 3.0 is built for riders who want the sharpest tool available in aero road cycling and aren't willing to compromise on the components that make a race bike perform at its peak. With Ultegra Di2 shifting, DT Swiss ARC1400 wheels, and a frameset purpose-built around the latest aero regulations, this is a complete race package — not a frame with mid-tier parts bolted on. It suits criterium racers, competitive century riders, and anyone whose standard for a road bike starts with what the fastest professionals in the world are racing on.
