Mixed-Surface Bikepacking Bike – Chromoly Frame 1×12 Drivetrain
$3,299.00
Whether you dream of local overnighters or round-the-world epics, Sunremo GRX 610 can help bring it to life. Its triple-butted steel frame and Cutthroat Carbon Deluxe fork create a comfortable-yet-durable ride that’s engineered for loaded touring on mixed terrain. Adjustable Alternator 1.0 Flat Mount dropouts let you tinker with wheelbase and ride feel, and cargo mounts galore give you the freedom to roam farther between resupplies. Shimano’s GRX 610 1 x 12 drivetrain is a smooth-shifting system with more enough gear range for climbing the Cordillera Blanca or capitalizing on tailwinds in Croatia. Sunremo’s ride quality and adaptability make it a smart choice for a steel bikepacking bike — we know you’ll go far together.
