Description
Argon 18 Equation 105 Di2 Road Bike
Designed for riders who want speed, control and exceptional value, the Argon 18 Equation 105 Di2 Road Bike is a modern mile-eating machine that thrives on long summer epics, fast group rides and challenging road conditions.
Precision Performance with Shimano 105 Di2 Electronic Shifting
The Argon 18 Equation is built around a performance-focused carbon frame that uses Argon 18’s proprietary design process and TCS (Topological Compliance System) technology. Each frame is individually analysed to optimise carbon layup and topology, delivering outstanding vertical compliance to absorb road vibrations while preserving stiffness for efficient power transfer.
Paired with Shimano 105 Di2 electronic shifting, the Equation offers crisp, effortless gear changes with race-proven reliability. The endurance geometry provides a stable, comfortable riding position for long days in the saddle, while staying true to Argon 18’s performance heritage.
Atten L42 Carbon Wheels: Speed, Control and Real-World Versatility
Completing the package are the Atten L42 carbon wheels, engineered to withstand the demands of competitive racing and challenging mixed-surface rides. Designed to strike the ideal balance between aerodynamic efficiency and lightweight performance, the L42 wheelset delivers rapid acceleration, responsive handling and excellent durability. A modern rim profile measuring 21mm internal, optimised for 28mm to 32mm tyres enhances comfort, grip and control, making these wheels feel confident and composed across varied road conditions.
