1983 Lennard Zinn 650B
Lennard Zinn built this all-purpose bike for his mother-in-law in 1983, when he was starting out as a frame builder. Lennard had recently spent time in the Redwood City, CA shop of Tom Ritchey, and had come home to Colorado with Tom's first 650B bike. Inspired by this wheel size, Lennard would go on to build a handful of bikes using this wheel system. The bikes used Super Champion rims from France, where the 650B size was commonly found on city, touring, and tandem bikes. Tires were Michelin Tandem with minimal tread, and were imported and available from Specialized Bicycle Company. The ultra-small frame has a toptube of just 46 cm (18 inches) and uses a generous rake of the fork blades to prevent interference with the rider's toes. The components are typical of the era, with Campagnolo Record high-flange hubs thrown in for a bit of class.
