The Trinity Advanced SL 1 is built for aerodynamic efficiency and sustained high speeds. The integrated cockpit allows fine adjustment of stack, reach and armrest position to achieve an aggressive, efficient aero fit. The stiff Advanced SL carbon frame maximises power transfer during hard efforts, while the deep-section SLR 1 50 carbon wheels maintain speed and stability in crosswinds. Wireless SRAM Force AXS shifting ensures precise gear changes without cables, and the integrated power meter enables structured training and race pacing. Hydraulic disc brakes provide consistent stopping power, even in wet conditions. Aero efficiency: optimised tube shapes and integrated storage reduce drag Race-tuned fit: adjustable cockpit for precise aero positioning Power-focused: integrated SRAM power meter for training and racing High-speed stability: carbon wheels and low-friction hubs maintain momentum WHY choose the Giant Trinity Advanced SL 1?
