TT3

Invent your future

Born to Win. Built to Last

The future of triathlon starts here.
Designed to push the limits of performance, the TT3 combines cutting-edge aerodynamics with exceptional stiffness. Every detail — from the frame profile to the fully integrated cable routing — has been optimized to convert every watt into pure speed. The result: a bike ready to take on the wind... and the clock

With the TT3, S1neo redefines what a triathlon bike should be. Lightweight, stable, and comfortable, it delivers a unique riding experience — even after hours of effort. Because in triathlon, the difference often lies in the details.

Tested in the wind tunnel and refined on the most demanding courses, the S1neo TT3 is the ultimate expression of aerodynamic performance. Its aggressive geometry and total component integration make it a pure concentration of efficiency.

This new triathlon model features the latest integrated technologies (dietbox, toolbox, waterbox). Each compartment — for nutrition, hydration, and essential tools — is perfectly built into the frame to optimize aerodynamics and efficiency.

The TT3 is crafted from Toray T1100 High-Modulus Japanese Carbon Fiber, offering exceptional tensile strength without compromising stiffness, power transfer, or vibration absorption. The result is a lightweight, stiff, comfortable, and incredibly durable frame .

A one-piece molding process ensures seamless construction — no more two-triangle assemblies like our 799D model. The TT3 is made for speed — and high speed. Whether you're racing a sprint triathlon or taking on the challenge of an Ironman, it will deliver both performance and pleasure. Adjustments are intuitive and limitless, helping you unlock your full potential.

Like all our products, the TT3 has been validated through extensive testing and certified by an independent laboratory. It fully complies with international safety standards (ISO/FDIS 4210-6).

A precision tool built to take you faster, farther, and higher on the podium. With the TT3, every detail brings you closer to your best performance.
