I've started riding my '02 Mercian Vincitore again. I wound up removing the 18T fixed cog I use for dirt roads and swapping in a 17/19T Dos Eno freewheel I picked up used. Yesterday and today are the first times I think I've ever ridden this bike with a freewheel instead of fixed cogs. I plan on flipping the wheel back around to the 16T fixed cog tonight, but I'll keep the freewheel because I can see how having a 60 or a 67-in gear and the ability to coast could be a good backup.
