Hattie Harnden Secures Historic Belt-Drive Victory at UCI World Cup Downhill

Hattie Harnden's groundbreaking win at the UCI Mountainbike Worldseries in Les Gets marks a pivotal moment for downhill racing. Her triumph as the first elite rider to conquer a World Cup event with a belt-driven bike not only secured her a significant prize but also ignited discussions about the future of drivetrain technology in professional cycling. This victory underscores the dedication of Harnden and her Aon Racing team, who have consistently pushed boundaries with innovative bike configurations.

Harnden Triumphs with Belt-Driven Innovation in Les Gets

In a thrilling display of skill and cutting-edge technology, British rider Hattie Harnden achieved an unprecedented victory at the seventh stop of the 2026 UCI Mountainbike Worldseries held in Les Gets, France. Harnden, riding for Aon Racing, ascended to the elite women's podium, making history as the first elite downhill racer to win a World Cup event on a bicycle equipped with a Gates belt drive. This remarkable feat earned her the substantial €100,000 “Belted Purse” prize, initiated by Gates in 2024 to incentivize innovation in drivetrain technology.

The “Belted Purse” was established to challenge traditional chain-based systems, encouraging elite-level riders to adopt and compete with belt drives. Initially offered in 2024, and subsequently extended to the 2025 and 2026 seasons after no rider claimed the prize, Harnden's victory finally saw the innovative challenge met. Several prominent teams, including Aon Racing, MS Racing, Intense Factory Racing, and Atherton Racing, had previously experimented with belt-driven setups in pursuit of this prize, highlighting a growing interest in alternative drivetrains.

Harnden's winning machine, a Gamux DH bike, has also garnered attention for its unique features, including a Pinion gearbox and an unconventional raised, reversed stem. This stem design, which places the handlebars noticeably higher than traditional configurations, had initially sparked debate regarding its impact on front-wheel weight distribution. However, Harnden's commanding performance, alongside teammate Reece Wilson's second-place finish in Andorra with a similar setup, has effectively silenced skeptics, demonstrating the efficacy of Aon Racing's innovative approach.

Expressing her excitement, Harnden remarked on the reliability and consistency of the Gates Belt Drive, emphasizing how it allowed her to concentrate fully on her race without concerns about dropped chains or gear slips. Her statement reflects a belief in the potential of this technology to make a critical difference in a sport where every fraction of a second counts. This victory, while a first in downhill World Cup history for a belt-driven bike, follows Harnden's previous success with a belt-driven Nicolai at the EDR stop in Pietra Ligure, Italy, last year, although that event was not eligible for the Gates prize.

Harnden's landmark achievement at Les Gets not only validates the performance capabilities of belt-drive systems in extreme downhill conditions but also poses a significant question for the future of mountain biking: could this signal a broader adoption of belt-driven drivetrains across the sport?

Hattie Harnden's historic win with a belt-driven bike could mark a turning point for mountain biking technology. Her success, along with the substantial prize money from Gates, might catalyze wider adoption of belt-drive systems, potentially revolutionizing how bikes are designed and ridden in competitive environments. This development challenges long-standing conventions and opens doors for further innovation in the sport.
