Wooden Bicycle - Need Help Picking Components
I am hobbyist woodworker and casual bike rider (mostly for exercise). On a recent vacation to California I happened to see a store that sold hardwood bicycles. At the time I was not able to go in, but the image of the hardwood bicycles hanging in the window has stuck with me. As a result I am going to be building my own hardwood bicycle frame. The woodworking part of it I feel pretty comfortable with. The main hangup I have right now are the components for the bike. I will have to purchase some of these components before I can begin my build since their dimensions will definitely influence how I build my frame.
I have two big concerns right now. The first and foremost is the front derailleur and how to attach it to the frame. Most front derailleurs clamp onto the bike with specific sized clamps. It will likely be very difficult for me to make my frame that precise size, mostly because my frame will likely be bigger and probably not perfectly round. Instead I will have to go with a direct mount front derailleur. Are there any direct mount front derailleurs that allow for greater freedom when positioning the front derailleur? The more the better in this case since I will be literally shaving away pieces of the frame to get it to mount correctly.
The second concern I have is where to find certain metal parts I will need. More specifically I will need 3 metal tubes and two wheel brackets? (not sure what to call them). I need a metal tube to go into the frame for where the seat post will mount, where the front fork will penetrate the frame, and for the crankset. I also will need metal brackets for the rear wheel to attach to.
To give you an idea of what I am trying to do here is a picture of a bike made by Renovo (the company that inspired this whole thing to begin with)
Thank you in advance for any help.
