Touring, Old-School

In the '70s and '80s this constituted the widest gear spread available. Suntour had that hard-to-find 38 tooth big cog for its Winner Pro™ series of rear clusters. They also had one of very few rear derailleurs that could handle the tension and the chain slack. There was also the Huret Duopar® and perhaps some others which are no longer in business. The 54 up front was a Sugino on a 110BCD five-arm crank. The sixteen was from a Mavic rear cogset threaded on a Mountain Tamer Quad which bolted on in place of the 74mm inner chainwheel's spacers.
