Description
Argon 18 Equation 105 Road Bike
Built for riders who want to go further and faster without sacrificing ride quality, the Equation 105 Road Bike is Argon 18’s formula for pure road riding enjoyment.
Comfort-Focused Carbon Performance for Longer Rides
At the heart of the Argon 18 Equation 105 Road Bike is a performance-minded carbon frame engineered for real-world riding. Using Argon 18’s proprietary design method and TCS (Topological Compliance System) technology, each frame is individually analysed to optimise carbon layup and frame topology. The result is exceptional vertical compliance that smooths out road buzz and dampens vibrations, while maintaining the stiffness you need for efficient power transfer. It’s the ideal carbon road bike for endurance rides, sportives and fast weekend miles.
Stable, Intuitive Handling with Proven Shimano 105 Reliability
Designed around Argon 18’s endurance geometry, the Equation delivers a stable, confidence-inspiring ride with a slightly more relaxed rider position – perfect for comfort over long distances, without losing the brand’s performance DNA. Borrowing carbon layup concepts from Argon 18’s Pro-level bikes, this cyclosportif-focused model offers sharp, intuitive handling and refined ride quality. Paired with the ever-reliable Shimano 105 groupset, you get crisp shifting, dependable braking and outstanding value, making the Argon 18 Equation Shimano 105 Road Bike a smart choice for performance-focused cyclists who demand more from every ride.
