Trek has unveiled a new cross-country (XC) race bike designed to meet the evolving demands of modern XC courses. This prototype, developed in collaboration with the Trek-Unbroken XC team, features a horizontal shock mounted to the top tube and flex stays, distinguishing it from previous models like the Supercaliber and Top Fuel.

The decision to create this new bike stems from the recognition that the sport has evolved, with longer rock gardens, drops, and trails that require more than the 80mm travel offered by the Supercaliber. Racers have often turned to the Top Fuel for these more challenging tracks, despite its additional weight. (racing.trekbikes.com)
Work on the prototype began in January 2024, aiming to craft the fastest 29er XC race bike possible. Trek’s engineers focused on developing a suspension platform that combines the best aspects of the Supercaliber and Top Fuel. They opted for flex stays and tested two different link options—a “swing” link and a “flapper” link—with the latter emerging as the preferred choice. The prototype offers 115mm of travel, providing sufficient support for the rough tracks encountered in today’s XC racing while maintaining an efficient pedaling platform. (racing.trekbikes.com)
In terms of frame design, Trek’s engineers prioritized weight and efficiency. By analyzing how different sections of the frame performed under stress, they were able to optimize tube shapes and material placement, resulting in a lightweight yet durable frame tailored for the demands of the World Cup circuit.

Despite the prototype’s advanced design and performance capabilities, Trek has stated that it is not intended for commercial release. The company views this prototype as a step in an ongoing iterative process, with insights gained from its development expected to influence future bike designs. (racing.trekbikes.com)
In related news, Trek’s factory mountain bike teams have rebranded as Trek-Unbroken, following a partnership with Unbroken, a Norwegian salmon-based recovery brand. This collaboration aims to enhance the teams’ competitive potential by providing resources to support their rigorous training and racing schedules. (racing.trekbikes.com)
