WHOOP UCI Mountain Bike World SeriesIn a groundbreaking move at the 2026 UCI Mountain Bike World Cup in Lenzerheide, the Thömus Maxon team unveiled their latest innovation: a full-suspension mountain bike equipped with 32-inch wheels. This development marks a significant departure from the traditional 29-inch wheel standard that has dominated cross-country racing for years.
The 32-Inch Wheel Revolution
The introduction of 32-inch wheels into competitive cross-country racing has been a topic of extensive discussion and experimentation. The Union Cycliste Internationale (UCI) has recently lifted restrictions on wheel sizes, allowing teams to explore this new frontier. The larger wheel diameter promises enhanced roll-over capabilities, potentially offering riders improved stability and speed over rough terrain. However, this advancement is not without its challenges, including increased weight and potential impacts on bike handling dynamics. (pinkbike.com)
Thömus Maxon’s Pioneering Prototype
At the Lenzerheide World Cup, Thömus Maxon showcased their prototype featuring a 32-inch wheel setup. The bike is equipped with a DT Swiss fork compatible with 32-inch wheels and a set of DT Swiss XRC1200 carbon wheels, shod with Schwalbe Racing Pro tires. These components suggest that the bike is nearing production readiness, indicating a serious commitment to this new wheel size. (brujulabike.com)
Rider Insights
Swiss riders Mathias Flückiger and Alessandra Keller have been spotted training on this prototype. Flückiger, standing at 173 cm, and Keller at 175 cm, are not typically considered large riders, raising questions about the compatibility of 32-inch wheels with various rider physiques. Flückiger expressed cautious optimism, stating, “We’ve tested the bike extensively, and the sensations are good, but we have to be smart. The most important thing is still to compete and not take unnecessary risks.” (brujulabike.com)
Industry Reactions
The cycling community is closely monitoring these developments. The potential benefits of 32-inch wheels include faster roll-over and increased grip, but concerns persist regarding increased weight and handling characteristics. As the UCI has permitted the use of 32-inch wheels in 2026, teams like Thömus Maxon are at the forefront of this technological evolution. (pinkbike.com)
