Last I heard the Bike Friday forks where made from seat stays. Is that right? We have had X employees here. Someone who could probably make one, if he was inclined to, and the price could be tolerated is English Cycles. He is very out of the box, and he is an X employee of BF. He uses the tiny rear triangle specs on his road bikes. Maybe a BF fork would fit, but there are a lot of dimensions that would need to be right for that to work. For one thing, most of their frames seem to use a tandem head tube.
