Battle Mountain 2004- Velox Solium / velox5One compact, all-in-one drivetrain/subframe. Some features: extra-narrow bottom bracket, two-stage chain drive to a Rohloff hub with disk brake, and a custom fork that was a senior's year-long project at Cal Poly. The head angle is 76 degrees and there's some negative fork offset in order to give it 1 3/4" of trail. They were allowing all sorts of people (including me!) to test ride it in the parking lot- usually after the first couple pedal strokes everyone could ride it without problems. It's really an amazing machine.
