• Progressive geometry for a stable, confident ride
• Suspension-ready for up to a 40mm fork
• T47 bottom bracket, UDH hanger and full internal routing
• Dropper-post compatible
• Multiple bottle and accessory mounts for adventure rides
• Full Shimano GRX 12-speed mechanical drivetrain
• Hydraulic disc brakes
• DT Swiss 1800 wheels built for rough terrain
• Stock 40c Schwalbe tires with room for bigger rubber
• Fast on pavement, planted on rough dirt
• Handles steep sections, switchbacks and technical terrain well
• Quiet, smooth ride feel from the carbon frame and internal routing
• Even better with a dropper post and larger tires
• One issue on our test bike was rear brake rub that needed shop correction
• Bottom line: a gravel bike that leans hard into off-road performance
