Giant 2026 Trinity Advanced SL Time Trial Frame & Fork

Product Overview

Lighter. Faster. More Control. Engineered to squeeze out every millisecond.

Every time trial is a battle against the clock. From windswept flats to technical descents, the course dictates everything—and the only constant is the ticking timer that determines a result. The 2026 Trinity Advanced SL TT is engineered to unlock new possibilities in that battle, combining straight-ahead aero efficiency with dynamic speed and an incredibly wide range of adjustments and adaptability.

Built on the exact same Advanced SL-grade composite frameset as the triathlon version, the TT frameset is made for time trials—developed, tested, and raced on prototype models by riders from the Jayco AlUla WorldTour squad. With a frameset that's 558g lighter and 5.9 watts faster than the previous generation Trinity Advanced Pro, plus all-new integrated solutions to help squeeze out more speed, it's the ultimate advantage in any race against the clock.

The differences between the TT and Tri versions come down to setup. The TT frameset includes an integrated down tube water bottle and cage designed specifically for aero optimization with the frameset, whereas the Tri version uses an integrated hydration reservoir and bento box.

Key Performance Factors

⚡ Full-Speed Dynamics – Built for Flat-Out Speed

• All-new composite frameset designed for flat-out speed and pinpoint control when racing against the clock

• 558g less weight for faster climbing compared to the previous generation

• Integrated disc brakes for confident cornering and descending

• Added compliance in the armrests and seatpost to help absorb bumps and vibrations for smoother ride performance

💨 Ultimate Aero Efficiency – Proven in the Wind Tunnel

• AeroSystem Shaping Technology with truncated ellipse tubing delivers a 5.9-watt aero advantage and greater stiffness-to-weight ratio over the previous generation Trinity

• Developed through Computational Fluid Dynamics (CFD) analysis combined with dynamic wind-tunnel testing

• Every tube shape and junction is meticulously shaped to minimize drag and control airflow across all relevant yaw angles

🎯 Personalized Fit – 24x More Adjustment Options

• Four seatpost offset positions (compared to two on the previous generation) offering a total range of 51mm (compared to 40mm previously) to help riders achieve an efficient, comfortable pedaling position

• 24x more armrest positioning options (stack, reach, angle and width) — easier than ever to dial in fit for all body types and any riding position using a simple two-bolt mechanism
