The edited lowlights/summary; any ride that involves stalling on hills twice, including one incidence of riding backwards downhill for a bit, before coming off, falling off when your right leg spontaneously unclips whilst riding uphill, falling off at traffic lights when you have a clipless moment, stalling in traffic cos you can't time your coming to a halt so as to have the pedals in the right place to start again, cannot be described as an unalloyed success.
Still, the last time I rode fixed was nearly 30 years ago. Once I get the new fixed 18t cog on I'll give it another go, in the mean time she stays singlespeed. 48/16 fixed is too rich for my taste buds.
