The Lava Dome is a versatile hardtail mountain bike that is just as happy exploring local trails as it is getting you across town. Its 9-speed drivetrain keeps things simple and dependable, while the clutch rear derailleur helps keep the chain under control when the trail gets rough. Size specific wheels give every rider a more natural fit, and clearance for tires up to 2.3 inches leaves plenty of room for extra grip and confidence. It’s approachable, capable, and ready to follow a casual ride wherever it happens to go. The Lava Dome has a way of turning a quick spin into a much bigger adventure.
