Description
Marin Four Corners 2 Gravel Bike
The Marin Four Corners 2 Gravel Bike is a steel-framed explorer built for versatility, equally at home on the daily commute or weekend adventures. Whether on asphalt or dirt, it offers comfort, capability and reliability for all kinds of riding.
The double-butted 4130 CrMo steel frame and fork are designed for comfort on rough roads and stability when fully loaded for touring or bikepacking. It comes equipped with six bottle mounts, rack and mudguard eyelets, lowrider fork mounts, generous tyre clearance, and disc brakes—making it ready for all terrains and all conditions.
Despite its classic appearance, this is no low-tech machine. Using biometric fit data, Marin offers five frame sizes, each paired with size-matched 650B or 700C wheels to suit riders from 4'11" to 6'4". A high front end provides all-day comfort and improved visibility, while off-road-ready geometry ensures confident handling when heading off the beaten path. It rolls on 44mm Vee Tire Quickstyx tubeless-compatible tyres, with clearance for up to 50mm, offering even more traction and control across mixed terrain.
