FAQ

Questions and answers relating to Argon 18 Equation Shimano 105 Asphalt Grey (S)

Is the Equation suitable for racing?

Answer

While its primary focus is endurance and sportives, the Equation is plenty fast for local circuit races or club tens. Its carbon layup is stiff enough for sprinting, though it prioritises comfort over pure aerodynamic aggression.

What is the maximum tyre clearance?

Answer

The Equation is optimised for modern road standards and can comfortably accommodate tyres up to 30mm or 32mm (depending on the rim width), allowing you to run lower pressures for increased comfort on rougher road surfaces.

How does the "Asphalt Black" look in person?

Answer

It is a sophisticated, stealthy finish. It features a matte/satin texture that resists fingerprints well and provides a premium, understated look that won’t go out of style.

Can I fit mudguards to the Equation?

Answer

The Equation is designed as a performance road bike; while it doesn’t have traditional eyelets for full-length guards, it is compatible with many high-end clip-on mudguards (like SKS Raceblades) for winter protection.
