From 2003-2015 or so, this 2002 Mercian Vincitore custom road fixed-gear was my primary gravel bike, running on 28 mm Continentals or Paselas - I would flip the rear wheel around to run 45x19 (later 42x18) fixed and it worked beautifully on the hardpacked dirt and gravel backroads and fire roads around Greenwood, SC -
But a couple of years ago I built up this 1973 Raleigh Competition, taking advantage of its greater clearances to run 35 mm Continental Cyclocross Speed tires. I've got a 17/19T Surly Dingle on one side of the flip/flop hub and a 20/22T White Industries Dos Eno freewheel on the other, allowing me 70-in fixed pavement, 60-in fixed gravel, then around 60-in general coasting and 51-in gentle singletrack options. It's a wonderful all-roads kinda bike.
