At the risk (certainty?) of being the noob who posts too much, i was under the impression that the way you rode a fixed gear was to have a gearing combo that would allow a decent cadence for most of the rides you go on -- a decent cadence being 80 or greater RPM. So I have just been killing myself trying to ride at a good RPM since i got the bike. I have ordered a 1T-bigger cog and we'll see how it goes from there.
