GR 500 Frame
The all-new 2027 GR 500. Built for the road less traveled and engineered to take you further.
Completely reimagined for 2027, the GR 500 brings together advanced titanium engineering, purposeful frame design, and the versatility to take on whatever lies beyond the pavement. Whether you're chasing gravel miles, exploring unfamiliar roads, or setting out on your next multi-day adventure, the GR 500 delivers an exceptional balance of performance, responsiveness, and all-day comfort.
Every detail serves a purpose. Our new square-formed down tube and pentagonal top tube work together to increase frame stiffness and power transfer, delivering a responsive, confident ride when the terrain gets demanding. Complementing this performance-driven design, our flattened and gracefully swooped seat stays provide additional compliance, absorbing the rough edges of the road and keeping you comfortable long after the miles begin to add up.
Versatility is built into its foundation. Featuring our house-made sliding frame dropouts alongside UDH-compatible sliding dropout options, the GR 500 accommodates a wide range of drivetrain configurations and gearing setups, giving riders the freedom to build a bike around their own style of adventure.
Backed by 40 years of titanium innovation and craftsmanship, the 2027 GR 500 is more than a gravel frame. It's an invitation to explore further, ride harder, and discover what's waiting beyond the next turn.
One frame. Endless possibilities. Your next adventure starts here.
