Leveraging the cutting-edge aero technology of the Noah Fast 3.0, we’ve made the Triton Fast the fastest bike in the peloton.

Aerodynamic storage system
The Triton Fast integrates a hydration and storage solution directly into the frame design. This system keeps nutrition and essentials within reach while maintaining optimal aerodynamics, so nothing slows you down.
Easily adjustable & removable cockpit
The Triton Fast features a cockpit designed for maximum adjustability. Extensions and base bar can be fine-tuned quickly, making it easy to find the perfect fit. Thanks to its modular design, the cockpit is also easy to disassemble for travel or maintenance.
Triathlon-specific, progressive fit
The Triton Fast features a progressive triathlon geometry that positions the athlete closer to the bottom bracket. The result: maximum power transfer combined with stability in every race situation.
Internally integrated hydration system
The Triton Fast features a fully integrated hydration system inside the frame. Designed for quick access without disrupting your aero position, it keeps you hydrated while staying fast.
Proven at the highest level

Adjustable fork rake
The Triton Fast is equipped with flip chips in the fork, allowing you to fine-tune the rake. This gives athletes the freedom to balance stability and agility according to race conditions and personal preference.

Help & support
How can we help?
The Triton Fast is designed with a UDH hangers. This means you can use all electronic groupsets on the market who need a regular hangern but also direct mount groupsets like the Sram Transmission groupsets.
The tire cleance of the Triton Fast 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.
The maximum torque to fix the seatpost clamp is 4Nm, like mentionned on the clamp
The Triton Fast is designed with its dedicated basebar to have a perfect aero integration with the frame.
You can use all extensions on the market with a bolt spacing of 15mm and we recommend the use of an M6 bolt to mount the extensions on the Monoriser Wing
The Triton Fast is developped for electronic groupset in a 1x or 2x configuration. The frame is compatible with traditionnal rear derailleurs and T-Type rear derailleurs
We use a BB86 press-fit bottom bracket standard on the Triton Fast.
The integrated seatpost clamp (Ridley article code SPCAER4ZA012) is designed for the aero seatpost of the Triton Fast.
When using a 1x setup the maximum chainring size is a 70T. When you prefer a 2x setup, the maximum inner ring size is 42T and outer ring is 62T
You can adjust the rake of the fork in 3 different positions thanks to the flipchips: 45, 50 or 55mm. Changing the rake of the fork has an impact on the handling of the bike: a short rake (45mm) will provide a stable and slower steering, a long rake (55mm) will provide a more responsive and faster steering.
The Triton Fast will be deliverd with a monoriser spacers set that goes from 2cm up to 10cm, in steps of 2cm. There are also 3 spacers of 0,5cm to finetine your position. The Monoriser wing where you mount the extensions will add another 20mm of stack to your stack.
The maximum heigth you can reach is 13,5cm (10+1,5+2).
The Monoriser Wing allows you to find your perfect position thanks to its rotational system. You are not limited anymore by spacers in fixed angle like 0°, 5°, 10° etc, but you can finetune the angle in every possible position.
