Technology News. I Edition 2013 Beautifully formed, bamboo frames perform at the highest level of the sport. Article created by: Marco Salas. Bamboo bicycle frames are very stiff, transferring power efficiently, are durable, resisting damage from stress and impacts; are comfortable, surpassing aluminum, steel, titanium and most carbon frames in smoothness. The Bamboo frames requires over 40 hours of labor to build. Following an interview with the frame’s new owner, we hand select a bamboo tube set that will deliver characteristics consistent with the riders expectations and requirements. Every frame is made to order and every frame is unique. All bamboo bicycles are available in stock or custom geometries. Our frame is made from bamboo that has been treated to prevent splitting. We finish the bamboo frames with satin polyurethane that functions as a vapor seal and allows the owner to maintain the bamboo frame as they would any metal or carbon frame. Lugs are made of pounded bark cloth from ficus trees. It use a plant based high performance eco resin to create the required matrix. Importantly, we discovered that bamboo and carbon fiber have different rates or thermal dynamic expansion. The early bamboo frames used carbon fiber, instead of natural fiber, to join the tubes and many of the joints failed over time. This problem was corrected with time and the joints were made with natural resins. This Bamboo frame with an integrated rear rack is a beautiful example of the flexibility in frame design afforded by our bamboo tubing and natural fiber lugs. Intended for loaded touring this frame features 35mm tire clearance, fender mounts, and long reach brake compatibility. 3
