First, hope you and the Calfee folks are all healthy and still able to work during the pandemic. Second, thanks again for all your assistance as I was building my bamboo frame. I finished the frame and built it out with fun SRAM gravel components. I’m enjoying riding it and getting lots of compliments about it. It really rides well. Since this is the first frame I’ve ever built, you and Craig’s videos were indispensable. I might change a…
On July 4, 2010, Joost Notenboom and Michiel Roodenburg, began a 20 month bicycle journey from Deadhorse in northern Alaska to the Antarctic Peninsula south of Ushuaia. Their mission was to take one bottle of icy Alaskan water from the Beaufort Sea down to the seas around Antarctica in a symbolic effort to complete the natural water cycle and raise awareness for the global water crisis that is leaving over 1 billion people around the world without access to safe and…
Concreet Table A flat table is key to building straight frames. Melamine chip board is fine for awhile but it will eventually warp, especially if left outside. Build a long lasting, warp-proof flat table out of reinforced concrete with a poured epoxy surface. Find a mostly flat floor to work on. Lay down a strong plastic sheet (Visqueen) that's at least 4 mils thick. Continue to instructions
Cable Stop Guide for Bamboo Cable stop are small parts that attach to the frame and hold the cable housing. They are glued on and screwed through the wrapping. View the PDF
Causes, Prevention and Fixes Causes: Splitting of bamboo is caused mainly by rapid changes in moisture content of the bamboo. This can be caused by rapid changes in relative humidity of the atmosphere, or the bamboo being dried unevenly, or getting soaked and then drying out too quickly. Some bamboo species are more prone to splitting than others. And thinner walled bamboo is more susceptible to splitting. Lastly, the septums of the bamboo (those little walls at each node) can…
It's all about the Bamboo We offer our bamboo bicycle frames in all frame styles and geometries. We enjoy this flexibility as we do not use forms or molds to join the bamboo tubes. As a result, there is no imposed constraint. We are able to miter and join the bamboo tubing at any angle to support complete personalization of the product. While they have long been popular with enthusiastic racers and endurance road riders, owing to our bamboo’s amazing…
How bike geometry measurements affect stability : Rake and Trail: Bike Fork Rake explained - this is also known as Offset, which more accurately describes what it is: the hub’s offset from the steering axis. Not to be confused with the curvature of the fork blades, which some people think of as “rake”. Straight blade forks can have plenty of offset. Fork offset determines trail when considered with head angle (and the diameter of the wheel). Trail is best thought…
Standard frame measurement terms ST: Seat Tube: Measured from the center of the bottom bracket along the center to a point near the seat post binder. The exact location of this point may vary between manufacturers depending on the frame design. The main purpose of this would be as a reference point and, if located at the seat binder, would indicate whether your favorite seat post would be clamped above the minimum insertion line. TT: Top Tube: Measured from the…
