Greenstar Bikes began researching bamboo as a frame- building material in 2010. Several prototypes were evaluated, first using carbon fiber lugs, then cast aluminum lugs, before arriving at the current model. The final design uses aluminum chain stays and welded aluminum lugs, with bamboo top tubes, down tubes, seat tubes, and seatstay tubes. Greenstar’s proprietary manufacturing process make this combination affordable and ecologically sustainable. Furthermore, the design produces a ride quality which is solid and responsive, while absorbing vibration.
