I wish that I could've entered my build Skin Deep for the WBO, but it doesn't seem to fit any of the rules. I've been getting my jig ready and I'll probably actually start work at about the same time as the rest of you. Maybe it'll get done quick and I can start another one for the bo.
Skin Deep definitely doesn’t fit the Vintage category but I thought you’d be ok for the Scratch-Built category and upon re-reading the rules, I see what you mean… you’re using the donor bike “back triangle” and “previously welded together sections” of frame tubing that disqualifies it from the Scratch-Built category.
Vintage bikes are usually quite expensive here when they turn up, which isn’t that often, so vintage is out for me if I want to participate. So it’ll be Scratch-Built if I enter and I do have an idea of what to do.
For those that might not have seen them, here are the WBO rules…
Vintage: Would rather not have a specific date limit on it, but if it is mass produced in China, it probably doesn't belong, think more of Chicago Schwinns, Spaceliners, Elgins, you get the idea...
Obviously this could put those outside the USA at a disadvantage, but what about lugged English Raleigh frames or similar? They are everywhere! Start looking around and I am sure most of us could find something old and interesting. Frame modifications are allowed!
Scratch-Built: Let's use the Uncle Stretch definition of Scratch-Built: "In order to qualify for a scratch built bike, you have to build it complete. If you use the head tube and bottom bracket from a built bike, that is acceptable, but you have to build the frame. That includes the back triangle."
You can use tubing from bike frames, but not previously welded together sections. You can use factory produced forks though!
We are seeing a lot of builders stepping into the scratch-built area and want to give them somewhere to play!
Maybe it'll get done quick and I can start another one for the bo.
