GIANT TRINITY ADVANCED SL 1 TIME TRIAL/TRIATHLON BIKE 2026 CARBON/MATTE CARBON

From windswept flats to climbs, corners and descents, the new Trinity Advanced SL delivers dynamic speed and control when every second counts. 

Easily adaptable to triathlon or TT, and featuring aero-integrated hydration and fuelling systems, it’s lighter, more aerodynamic and smoother riding than the previous generation, with greater adjustability to dial in position and fit. 

Key Features

• The new Trinity Advanced SL is built on an Advanced SL-grade composite frame and fork that’s 558g lighter than the previous generation.
• New disc brake integration for greater control along with added compliance in the armrests and seatpost to help absorb bumps and vibrations.
• The front end of the bike is totally redesigned with more armrest adjustments for stack, reach, angle and width, while a wider range of seatpost offset options allows the rider to dial in a powerful, comfortable pedalling position.
