Giant, Liv, and Cadex Unveil New Time Trial Bikes and Wheels in Anticipation of the 2025 WorldTour Season

Today, Giant, Liv, and Cadex have introduced an array of cutting-edge time trial technology that will be utilized by Team Jayco AlUla and Liv AlUla Jayco in the forthcoming WorldTour season.

The latest time trial bikes, which come in triathlon-specific configurations featuring enhanced storage solutions for gear, nutrition, and hydration, showcase advancements in multiple areas. These include enhanced aerodynamics, decreased weight, superior fit options, and better handling capabilities. Additionally, the Cadex wheels contribute to these improvements with their lighter weight and aerodynamic design.

Thanks to the use of what Giant calls Advanced SL-grade composites, the Trinity Advanced SL TT frameset is a whopping 558 grams lighter than the previous generation Giant TT frame, resulting in a 12 percent improvement in the bike’s stiffness to weight ratio, according to Giant. That should make for a bike that accelerates quicker and climbs faster, both important aspects of modern time trial bikes as the race of truth continues to become more technical and punchy rather than being a simple straight-line speed test.

Giant offers a complete package that encompasses all the features you would anticipate from a high-end time trial bike today, including seamless integration and disc braking systems.

The front end of the bike offers extensive adjustability to accommodate a diverse range of time trial positions. You can modify the stack, reach, angle, and width of the armrests to fit your preferences. The stack height can be adjusted from 60mm to 80mm, while the reach can be set between 60mm and 75mm. The armrest width has expanded from six to eight settings, and riders can choose from three different armrest angles (0, 10, or 15 degrees). Additionally, there are four seatpost offset options, allowing for 51mm of adjustment to achieve a more precise fit at the rear of the bike.

Time trial bikes have long been the final stronghold for rim brakes within the WorldTour peloton, with a few manufacturers still clinging to this traditional technology. However, the introduction of the Trinity Advanced SL TT signifies another shift away from rim brakes. Surprisingly, even with the inclusion of disc brakes, this bike boasts improved speed compared to its predecessors. Giant utilized a combination of advanced computer-aided Computational Fluid Dynamics (CFD) analysis and practical wind tunnel testing to optimize the design of each tube, focusing particularly on the areas surrounding the disc brake calipers.

Giant asserts that the new model offers a 5.9-watt aerodynamic benefit over its predecessor, but does not clarify the extent to which this improvement can be attributed to the integrated storage features of the triathlon-specific variant.

Nonetheless, the bike has already demonstrated its effectiveness in real-world conditions. Luke Plapp has played a key role in its development, testing prototypes during the Olympics and recently clinching his third Australian time tr
