  • 2017 Marin Urban

Bike Description

The Muirwoods 29er is our rough and tumble commute machine. Offering the toughness of a mountain bike-based chromoly frame and fork with an updated geometry and durable component selection, this bike is designed for riders wanting some fun on their commute. From jumping curbs and train tracks to adventuring the dirt roads on the outskirts of town, the Muirwoods 29er can take it all. A 27-speed Shimano Altus and Alivio drivetrain provides the perfect gear regardless of terrain while Shimano hydraulic disc brakes provide dependable braking performance regardless of weather conditions. Night time visibility is taken into account with highly reflective 3M graphics on the frame and tires, while integrated rack and fender mounts allow you to build up the bike to best suit your needs.
