Sorry, no bamboo folder. (Although I might change my mind in the future). Since I have a limited time to see patients, I figure that I'll focus on the rootcanals and crowns now, and think of bamboo folders later. My original vision was the Swift in bamboo: 1. it's a simply hinge that doesn't require propietary parts, and can be built big without hampering effectiveness. 2. The frame design is very strong--while a unitube probably shouldn't be done with bamboo, it'd be not too hard to have a simple truss. 3. The bike itself is a joy to ride, very efficient and stiff. It wouldn't be too hard to adapt whatever parts you want to add, provided that it can be on the original Swift. After riding on the Xootr swift for the past several months, I've really fallen in love with the bike. It's top speed is a bit limitted compared to some fancy road bikes and it's not good for offroading, but it's ideal for street riding. It's also very fun and solidly built. My main issue was building the Jigs. I'm currently too anal, and too lazy to build it (I'd rather graduate first).
