Cycling Tech Company Gravaa Declared Bankrupt

The Dutch firm Gravaa, known for its cutting-edge Kinetic Air Pressure System (KAPS) utilized by cycling teams like Visma-Lease a Bike, has entered bankruptcy proceedings. This development comes despite the system's presence in major events such as Paris-Roubaix and the UCI Gravel World Championships.

According to official Dutch court records, administrators have been appointed to oversee the company's liquidation. Gravaa's KAPS technology allowed cyclists to dynamically adjust tire pressure during rides, offering a strategic advantage on varied terrains.

The KAPS system gained prominence through its adoption by Visma-Lease a Bike in recent editions of Paris-Roubaix. Notably, Marianne Vos employed the system en route to her victory at the 2024 UCI Gravel World Championships, and Pauline Ferrand-Prévot also rode a Gravaa-equipped bike to win Roubaix the previous year.

Introduced in 2021, the system's core innovation lay in its ability to enable riders to inflate or deflate tires while in motion. This was achieved through a miniature compressor integrated within the wheel hub, which fed pressurized air into the tires via an electronically controlled Presta valve. Control buttons on the handlebars facilitated these adjustments, with options to link to bike computers for real-time pressure data display. The strategic benefit was clear: riders could lower tire pressure for enhanced grip on challenging surfaces like gravel or cobblestones, then increase it for optimal speed on asphalt.

The technology operates on a kinetic compressor principle, harnessing the wheel's rotation to draw in and pressurize ambient air. Gertjan van Ginderen, Gravaa's founder, explained in an interview with Cycling Weekly earlier this year that the inflation rate was directly proportional to the distance covered. For instance, a 42mm tire could see its pressure increase by approximately 0.8 bar (11.5 PSI) per kilometer.

However, commercial viability proved elusive for Gravaa. In a recent communication, John Zopfi, the company's commercial director, stated that the necessary capital and firm commitments from potential high-volume customers for scaling up production never fully materialized, leaving no alternative but bankruptcy. Challenges related to compatibility with tubeless tires and pricing were identified as significant hurdles. Despite the current situation, there remains a possibility for the technology to find a new owner. Zopfi indicated that a curator would assess whether components of the company, its technology, or the brand could be acquired and continued under different ownership.
