This is a 1994 Bridgestone MB-1 that has been upgraded with a 14-speed Rohloff internal gear hub. The MB-1 was Bridgestone's top-of-the-line mountain bike in 1994. The frame size is 46 cm (18 in). The bike is in mechanically great shape and is ready to ride. In the process of building this bike with the Rohloff hub I cleaned all components and applied grease/anti-seize where applicable. Gear shifts are smooth. The headset and chain were recently replaced (< 100 miles). The original cantilever brakes are properly adjusted and provide reliable stopping power. The bike will be professionally packed and shipped by University Cycles in Boulder, CO. You are welcome to come take a look in person if you are around the area.
