- WeightThe most accurate way to determine any bike’s weight is to have your local dealer weigh it for you. Many brands strive to list the lowest possible weight, but in reality weight can vary based on size, finish, hardware and accessories. All our bikes are designed for best-in-class weight and ride quality.

Highlights
Designed using Computational Fluid Dynamics and dynamic wind-tunnel testing, the Trinity Advanced Pro delivers a proven aerodynamic advantage. Handcrafted from premium Advanced-grade composite and meticulously formed with AeroSystem Shaping Technology, this is the choice of Giant pro triathletes including Ironman 70.3 World Champion Gustav Iden. It offers a comfortable fit for long distance training and racing nd its unique AeroVault system includes an integrated front hydration unit, top tube storage box and downtube water bottle that, together, actually improve the bike’s aero performance on the road.

Advanced Composite Frame
Aerosystem Shaping Technology
Through CFD and dynamic wind-tunnel testing, engineers optimize each tube shape to deliver superior aerodynamic performance.
Aerodrive Tri Composite Base Bar
Trinity’s proprietary, triathlon-specific 5:1 airfoil base bar delivers the ultimate in aerodynamic performance and features a reversible design, giving riders 40-millimeters of height adjustment.
PowerCore
A massively oversized bottom-bracket/chainstay area features a fully integrated, 92-millimeter-wide bottom-bracket design. Asymmetric chainstays provide additional stiffness on the driveside and stability on the non-driveside.
AeroVault System
Developed concurrently with the frameset using CFD analysis and wind-tunnel testing, AeroVault delivers a hydration and storage solution that also increases Trinity’s aerodynamic performance.
Internal Cable Routing
All-new internal cable routing hides derailleur and brake housing from the wind for maximum aerodynamic advantage and improved aesthetics.
