Brunello GRX11

Just like the wine it's named after, the Brunello surprises you when you get a taste of it. An all new aluminum gravel frame and full carbon fork easily handle the needs of the road enthusiast turned gravel rider. With its dropped chainstay, massive tire clearance, gravel-specific geometry, and 1X Shimano GRX drivetrain, the Brunello is ready for you to choose your own adventure.
