Overview
About this bike
Take on the streets with the Metric 3 Riding the line between a lightweight, nimble road bike for speed and a mountain bike for sturdy, stable handling in a more upright position, the Metric 3 makes a great city bike or commuter bike. Whether you are looking for a fun ride down the local greenway or through the city on your way to work, the Metric 3 is your perfect companion. The 700c wheels and custom alloy frame keep the ride quick and efficient while flat handlebars give you that mountain bike stability. This all-around street bike offers fast and smooth 35c tires that are wide enough to tackle any obstacles the pavement throws at you. With a Shimano Acera 9 speed drivetrain, rack and fender mounts, and strong double-wall wheels, you'll always be equipped for your next adventure.
