1973 Raleigh Competition Mk. II running 42/44T chainrings with a 17/19T Surly Dingle fixed-gear cogset on one side of the Surly New Track hub, White Industries Dos Eno 20/22T freewheel on the other - which gives me 70-in pavement and 60-in gravel fixed-gear settings, a 60-in general coasting option and a 52-in gear in case I feel brave enough for some gentle singletrack. Currently wearing 35 mm Continental Cyclocross Speed tires I picked up cheaply a couple of years back.
... and seen here in the wild -
