A very special touring bike built by Watanabe for Mr. Watanuki. This is a "demountable" -- it separates into two halves via quickrelease joints on the top and downtubes. Note the shift levers on the seat tube to avoid bridging the separation. The bar bag and front racks are also demountable designs, making it a snap to remove the bags. This arrangement makes it easy to do tours with a mix of train travel and riding, as the bike can be broken down into more easily stowed pieces.
