If you look at the rear brake bridge clearance it seems to me that this bike was definitely designed for 26" wheels. I think that someone stuck a 700c fork on it in order to increase the stack and get the handlebars up higher. Look at the relation of the bottom bracket to the rear axle. They're almost at the same height, which suggests that the entire frame has been rotated (counterclockwise as we look at it), due the increased axle to crown length. Look at the huge gap between the top of the front tire and the fork crown. I'm pretty sure that the redoubtable Bill Davidson would never let a frame built this way out of his shop. I smell a rat here, there's fuckery afoot.
