The G SES provides balanced and aero weight for real-world speed across all terrain, at the lightest weight possible. G SES is where aerodynamics meet the realities of modern gravel. The G SES 4.5 builds off the profilic success of the SES 4.5's design by delivering top honors in aerodynamics, handling dynamics, versatility, and weight savings when compared to gravel aero wheels of equal or greater depth, with the exception of the G SES 6.7.
