Bossi Grit Titanium Gravel Frameset – Built for the Long Haul

Discover the ultimate blend of durability, versatility and performance with the Bossi Grit Gravel Frameset. Precision-engineered from premium titanium and designed for modern gravel riding, the Grit is built to handle everything from fast-paced gravel racing to multi-day bikepacking adventures.

Premium Titanium Construction

Crafted from aerospace-grade 3AL-2.5V titanium tubing, the Bossi Grit delivers the perfect balance of strength, compliance and low weight. Titanium’s natural vibration-damping properties provide exceptional ride comfort over rough terrain, while its corrosion resistance ensures your frame looks and performs like new for decades.

The frame is finished with advanced 3D printed 6AL-4V titanium dropouts, offering enhanced stiffness and precision where it matters most. This cutting-edge construction method allows for optimised strength, seamless integration, and long-term durability.

Designed for Modern Gravel Performance

The Bossi Grit is engineered around contemporary gravel standards, giving riders the flexibility to build their ideal setup.

• Massive 700 x 50mm tyre clearance for maximum grip, comfort and control

• Compatible with both integrated and non-integrated cockpits for total build customisation

• Equipped with a UDH (Universal Derailleur Hanger) for easy replacement and compatibility with the latest drivetrain systems

Whether you’re chasing podiums or exploring remote backroads, the Grit adapts to your riding style.

Versatility Without Compromise

From fast, hard-packed gravel to technical off-road routes, the Bossi Grit frameset is designed to inspire confidence. The generous tyre clearance allows for aggressive tread patterns and lower pressures, improving traction and stability across mixed terrain.

Its refined geometry balances responsive handling with all-day comfort — making it equally suited to endurance events, gravel racing, or fully loaded adventures.

Built to Last – 50 Year Warranty

Quality you can trust. The Bossi Grit is backed by a 50-year warranty, reflecting the durability of titanium construction and Bossi’s commitment to craftsmanship. This is a frameset designed not just for today’s rides, but for a lifetime of riding.
