I've been riding a fixed gear road bike on my daily commute for 5 months now and am really beginning to feel the benefit. The gearing is quite high, 48×17, but my route is best described as undulating, although certainly not flat. At first I would try to keep the cadence high and get out of the saddle whenever needed. However, for the last week or so I have been extending the journey home from 3.5 miles to nearly 20 and instead of getting out of the saddle to keep spinning, I have been sitting and concentrating on good technique and power instead. I've also been trying to keep my heart rate down on the flats. Anyway my question is, do you think that this is a more beneficial way to ride fixed or has the wind simply been behind me?
