Sam Patterson may not be a household name to the average cyclist, but he’s had a great deal of impact on the cycling world. Patterson, namesake of FSA’s Metropolis Patterson Transmission, co-founded SRAM back in 1986, where he designed the ubiquitous Grip Shift shifters. Since leaving SRAM in 2000, Patterson has spent countless hours designing and prototyping fun stuff in his backyard workshop. He now has his sights set on redesigning the bicycle drivetrain as we know it—this transmission is just the first step. Patents are pending on other designs, so keep your eye out for some interesting stuff from Patterson.
Patterson isn’t a fan of front derailleurs, due to their complexity and clutter, so he’s spent the last 20 years brainstorming alternatives. Design sketches of the Metropolis Transmission were first put to paper back in 2006, and from that point Patterson began building rideable prototypes.
The Patterson is a two-speed crankset and bottom bracket unit similar in design and execution to SRAM’s HammerSchmidt and the Schlumpf Speed-Drive. Unlike the HammerSchmidt, which requires frame-mounted ISCG tabs, the Patterson is compatible with any standard 68mm bottom bracket shell. Installation is more straightforward than you might imagine, easily executable by a home mechanic with proper tools and moderate mechanical aptitude. ….Read Full Article at Bicycle Times: Link
