Trek's New 32-inch Wheel Mountain Bike for World Cup: An Initial Look

Trek is making headlines in the mountain biking world with the introduction of a new cross-country race bike featuring unconventional 32-inch wheels, slated for its competitive debut at the World Cup. This bold move by a leading brand, showcased by rider Evie Richards, hints at potential shifts in professional racing equipment. The prototype bike, adorned with special Pirelli tires and boasting a more relaxed frame geometry, signals an intriguing development. Its performance on the challenging Utah tracks will be closely watched by enthusiasts and industry experts, as it could pave the way for a new standard in competitive cycling.

Trek's Prototype 32er Mountain Bike Makes World Cup Debut with Evie Richards

In mid-September 2026, the cycling community witnessed an exciting development as Trek introduced a groundbreaking mountain bike at the World Cup cross-country races held in Soldier Hollow, Utah. Professional athlete Evie Richards was selected to pilot this innovative machine, distinguished by its unique 32-inch wheels. Initial glimpses of the bike, shared by the Wisconsin-based manufacturer earlier that week, sparked considerable interest and speculation regarding its specifications and potential impact.

A notable feature of this new model is its set of prototype Pirelli 32er tires. These tires, conspicuously branded with 'prototype' in capital letters on their sidewalls, mark Pirelli's entry into this emerging wheel size. While the exact width of these new tires remains to be confirmed, observations suggest they might align with the 32x2.4-inch dimension increasingly favored for lightweight XC applications, indicating a strategic choice for high-performance racing. The tire's tread pattern appears to resemble Pirelli's Scorpion XC RC, a design well-regarded in World Cup competitions.

Further analysis of the bike's design reveals a notably slack geometry for an XC race model. Based on visual estimations, the head tube angle is approximately 65 degrees, a significant departure from the 67.5-degree angle found on Trek's Supercaliber. This suggests a design philosophy aimed at enhanced stability and control on demanding terrain, potentially at the expense of climbing efficiency. The chainstay length and bottom bracket drop are also thought to be more generous than those on the Supercaliber, contributing to a more aggressive riding stance. Despite her stature, rider Evie Richards (approximately 160cm or 5'3") utilizes a size medium frame, necessitating a negative-rise stem to achieve her preferred handlebar height, underscoring the bike's tall stack design.

Trek's decision to launch a 32er in such a high-profile event positions them as a pioneer among major manufacturers. Although rumors of similar developments circulate among brands like Cannondale and BMC, Trek is the first to put a 32-inch wheel bike into World Cup competition. This initiative follows the successful third-place finish of Alessandra Keller on a Thömus 32er in a short track XC race earlier in the year, highlighting the nascent potential of this wheel size. All eyes will be on Richards' performance, especially following her second-place finish at the UCI World Championship XCC race, to see how these larger wheels influence race dynamics and outcomes.

The introduction of Trek's 32er mountain bike at the World Cup races could represent a pivotal moment for the sport. This daring innovation challenges established norms and invites a re-evaluation of optimal wheel sizes for cross-country racing. Should this new configuration prove successful, it might inspire other manufacturers to explore similar designs, leading to a new era of performance and capability in competitive mountain biking. The move also highlights the continuous pursuit of marginal gains in professional sports, where even subtle changes in equipment can yield significant competitive advantages. It will be fascinating to observe how this trend unfolds and reshapes the future of off-road cycling.
