Announced by the WHOOP UCI Mountain Bike World Series on 30 October 2026, Thömus maxon’s 2027 roster news gives women’s cross-country followers a tidy read on where one Swiss squad is placing its chips. Alessandra Keller has extended with the team, Monique Halter is already part of the professional set-up after stepping up during 2026, and British rider Charlie Aldridge will join from the 2027 season as Thömus maxon’s first international rider.
Keller stays at the centre
Keller remains the headline name for the women’s side of the squad. The announcement describes her as a former UCI World Champion and UCI World Cup overall winner, and her contract extension keeps a proven Swiss leader in place as the team strengthens for another crack at top-level international mountain biking.
Halter’s move matters too, especially for anyone watching how young riders find a route into elite racing. The source says she stepped up from the Thömus Akros Youngstars development set-up to the professional team during the 2026 season, while her younger brother Nicolas Halter will follow for 2027. Both were crowned U23 UCI XCC World Champions in 2026.
Aldridge adds international heft
Aldridge is the major incoming signing. The British rider joins after a 2026 campaign that included victory at the final UCI XCO World Cup at Lake Placid Olympic Sites, three further UCI World Cup podiums, silver medals in both XCC and XCO at the UCI Mountain Bike World Championships, and two gold medals at the UEC European Mountain Bike Championships.
The team is also changing behind the tape. Phil Dixon joins the athletic staff as Sports Director, with Kenta Gallagher named Race Coach and Test Rider. According to the announcement, the reinforced roster and staff are part of Thömus maxon’s plan to raise performance across the squad while retaining strong Swiss foundations.
Why it matters for XC fans
For women who follow the sharp end of XC, this is a squad-stability story with a bit of bite. Keller stays, Halter’s pathway is visible, and Thömus maxon is adding international firepower without walking away from its Swiss base.
