The Sandstone 40 is a modern allroad bike, equally capable on road and gravel. With Merlin’s custom 3D printed titanium chainstay yoke, the SS40 is capable of clearing a 700x40mm tire with short 420mm chainstays. The bike is designed to accommodate road drivetrains, giving you a narrow Q-factor and road gearing. The Sandstone 40 is the most versatile bike in our lineup: set it up as a lightweight and efficient endurance road bike or a fast and racy gravel bike.
