Liv/Giant 2017 Avow Advanced Pro 0 (Composite/Orange/Purple)
Historically, the terms ‘comfort’ and ‘tri bike’ do not go hand-in-hand, but Liv decided to reshape that trend. The Avow Advanced Pro is leading the way with a women’s-specific customizable fit, so you can stay fresh while performing at the highest level. Nothing keeps your mind and body sharper than fueling up, that’s when the hands-free hydration system and aerodynamic snack box quickly leap up to ‘favorite features’ status.

ADVANCED COMPOSITE TECHNOLOGY
Giant's High Performance-grade raw carbon fiber is used to produce custom composite material in our own composite factory. Extremely lightweight, stiff and compliant, these handcrafted frames feature the following materials and processes:
- MATERIALS: High Performance-grade raw carbon material features an excellent stiffness-to-weight ratio.
- RESIN: High Performance formula provides excellent void minimization (bubbles) while maintaining outstanding strength. And vibration absorbing particles are added to help disperse road shock.
- MODIFIED MONOCOQUE CONSTRUCTION: The front triangle (downtube, headtube, toptube, seattube) is assembled and molded as one continuous piece. This front half is then joined to the rear chainstays and seatstays in a secondary process. This process eliminates the outermost woven composite sheet to reduce weight without affecting ride quality, strength or stiffness.
AeroSystem Shaping Technology:
Through CFD and wind-tunnel data, engineers optimize each tube shape to deliver superior aerodynamic performance.
Liv's unique 3F design philosophy ensures that, as a female rider, you are getting the best bike for your riding style. 3F stands for "Fit, Form, Function." These are the elements that guide Liv engineers and designers as they create your bike, apparel and gear. The 3F design philosophy produces the best and most appealing cycling equipment to help all women feel confident and enjoy the ride.
Liv bikes, apparel and gear are designed specifically for women. Liv's team of female designers and engineers consider all aspects of a woman's unique strengths and physical characteristics to create the only complete product collection designed solely for women. Examples of this include:
- Women's-specific fit based on global body dimension studies
- Optimized stem lengths, handlebar width and drop, and crank arm length
- Shorter brake reach
- Comfortable saddle designed for female pelvis and hip shapes
- Liv ApparelFit System with multiple fit options
Liv designers understand the importance of creating bikes, gear and apparel pieces that not only meet the highest performance standards, but also have a great look and feel. From crafting the lightest, smoothest riding bikes to designing distinctive color and graphics combinations, the Liv team is committed to providing the highest level of design and aesthetics. Examples include:
- Thoughtfully considered frame design
- Dynamic use of color and graphics to create eye-catching designs
- Color matching between rider gear and bikes
- Flattering cuts and styles in all apparel items
- Application of fashion color trends and patterns
Liv defines function by how well a product performs in its element. We strive to create lighter, faster, more confidence-inspiring bikes and products for women. Here are some of the ways Liv emphasizes Function:
- Utilizing Giant's world-leading craftsmanship and technology to produce a premium product collection
- 3F layup schedule results in custom, ultra-lightweight frame construction for the unique needs of female riders
- Functional fabrics keep you comfortable and performing at your best
- Women' s-specific chamois technology to fit female anatomy
1. SUPERIOR AERODYNAMIC PERFORMANCE
Using extensive CFD analysis and dynamic wind tunnel testing, more than 250 different frame configurations were developed and tested before finalizing the 2016 Trinity Advanced Pro frameset. To provide triathletes the ultimate aerodynamic advantage without any UCI constraints, the Trinity Advanced Pro is engineered with triathlon-specific features and optimized with Giant’s AeroSystem Shaping Technology. The result is the fastest Trinity ever.
Beginning in 2010 with a 3D scan of Giant test rider and former professional racer Grischa Niermann, Giant and development partner Aero Concept Engineering created a new, dynamic approach to wind-tunnel testing using an exact 1:1 scale mannequin, aptly named “Grischa.”
Designed with anatomically correct articulating legs, this dynamic mannequin allows Giant engineers to measure not only pressure drag and friction drag, but the precise aerodynamic interaction that occurs between the rider and bicycle while in motion—a feat not achievable using CFD or industry-standard wind-tunnel testing. By using a dynamic mannequin rather than a human rider, Giant is able to perform consistent testing, eliminating unwanted variables such as changes in body position or pedaling cadence.
In addition to Grischa, a one-off aluminum CNC’d prototype frame was developed to give Giant engineers the ability to quickly test different frame and component designs in the wind tunnel. Through this comprehensive process using both CFD analysis and dynamic wind tunnel development and testing, Giant engineers confidently optimized the Trinity Advanced Pro’s AeroSystem frame design for real-world aerodynamic performance.
(From left to right) The development process begins with extensive analysis using Computational Fluid Dynamics (CFD). Dynamic testing in the wind tunnel using an aluminum prototype frame and the Grischa mannequin allows Giant engineers to test frame designs in real-world conditions. Production sample wind tunnel testing verifies Trinity’s performance before commercial release.
AeroSystem Shaping Technology
Giant’s AeroSystem Shaping Technology is an approach to frame design that analyzes the distinct airflow conditions each area of the frame encounters to maximize the performance of the frame as a cohesive unit. Every tube profile, position and junction has been engineered, developed and tested extensively to work together to minimize drag and control airflow across all relevant yaw angles.
When compared to Trinity Advanced Pro’s TT configuration, the triathlon-specific components reduce drag by an average of 15 watts at 50kph across 0-30 degrees yaw.
2. INTEGRATED AEROVAULT SYSTEM
Triathletes must carefully manage hydration and nutrition needs on the bike. The AeroVault System delivers an engineered approach to hydration and storage that doesn’t sacrifice aerodynamics. By developing the AeroVault System and Trinity frameset as a cohesive unit, this is the only triathlon bike tested that is actually faster with hydration and storage installed than it is without.
Wind Tunnel Testing:
To validate Trinity’s aerodynamic performance as a complete system, Trinity and four key competitors were tested at ACE wind tunnel in Magny-Cours, France. Each bike was tested with and without its corresponding hydration and storage components to determine the most accurate aerodynamic performance in a race-ready configuration. Developed with AeroVault as a cohesive unit, the Trinity Advanced Pro was the only bike that was more aerodynamic with its hydration and storage components installed than without.

3. TRIATHLON-SPECIFIC FIT
The grueling distance of triathlon competition requires riders to balance aerodynamic performance with comfort. The 2016 Trinity Advanced Pro features improved geometry and functionality for triathletes to help riders achieve their ideal fit. Along with refined frame geometry, Trinity Advanced Pro’s cockpit design features a wider range of adjustability and a simplified assembly.
REFINED FRAME GEOMETRY
Working with a global community of athletes and bike fit professionals, Giant engineers reevaluated and refined Trinity’s frame geometry to meet the needs of triathletes of all sizes, shapes and fitness levels. Now offered in four frame sizes rather than three, Trinity Advanced Pro provides a wider overall fit range than before. Trinity’s proprietary 80-millimeter length AeroDrive stem is better optimized for bike handling from the extensions, and features a triathlon-specific design with 30 millimeters of additional rise compared to the AeroDrive TT stem.
