Everett, Washington Patent of the Year – 2024/2025
Dive Xtras Inc. has been awarded the 2024/2025 Patent of the Year for innovation in mechanical reliability. Their invention, detailed in U.S. Patent No. 11919592, titled ‘Devices for retaining a bicycle chain on a sprocket’, introduces a smart solution to a common cycling problem: dropped chains.
The new technology improves chain stability during shifts and under stress, helping cyclists maintain control and avoid mechanical failures. The patented device uses a simple yet effective mechanism that keeps the chain aligned and securely in place on the sprocket, even during intense movement or rough terrain.
Unlike traditional guards, this system integrates seamlessly into the drivetrain without interfering with performance or adding bulk. It works across a wide range of bikes, making it valuable for both recreational riders and serious athletes. The invention also reduces wear and tear by preventing misalignment and slippage, extending the life of both chain and sprocket.
Dive Xtras Inc., known primarily for underwater propulsion systems, brings its precision engineering expertise to land with this new cycling innovation. By tackling a longstanding frustration in bike maintenance, the company delivers real-world benefits for safety, performance, and durability. This advancement highlights how small design changes can lead to major improvements in user experience.
