The Greenstar Bikes EcoCross Hybrid Frame is a multi-purpose frameset that can be used for any number of bike builds: mountain bike, commuter bike, gravel bike, hybrid bike, comfort bike, even a road bike. Perfect for streets, trails and off-roading, the EcoCross bamboo frame will help you zip up hills and enjoy your ride on almost any terrain. The bamboo and recycled 6061 aluminum lugged frame delivers an ultra smooth ride by absorbing micro vibrations. This affordable frame weighs only about 5 pounds, and still has all the beauty, quality, and performance of a bamboo bicycle from Greenstar Bikes. Stunningly available in black.
