Equation 105 Di2 Road Bike

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.
