The Muirwoods is built upon a tough mountain bike foundation with a big dose of speed and agility through an updated geometry and component selection. The result is a bike with a durable cromoly frame and fork that can jump curbs and dodge potholes as you make your way through the urban jungle. A 24-speed Shimano Altus and Alivio drivetrain provides the perfect gear regardless of terrain while Tektro hydraulic disc brakes provide dependable braking performance regardless of weather conditions.
3M Reflective Decals
Urban bike frame treatment that utilizes a special reflective decal application. These decals are scratch resistant and maintain the base color of the frame under natural light to offer a stealthy appearance. Once illuminated by the lights of a car, street lamp or other bikes, a reflective prism element in the decals bounce the light back, resulting in a bright outline of the decal panels on the frame for maximum visibility in dark conditions.
Security Skewer System
Integrated wheel and seatpost skewers included on Marin Urban and Speed Commuter models with specially designed heads that require a dedicated tool for operation, deterring possible theft of parts. Special removable hex wrenches are included with each bike for fastening. CNC’d aluminum sleeves encase the bolt heads to prevent loosening with pliers or vise grips.
