It gives me the willies when I see some people riding their bikes, grinding out their precious knees. "Raise your seat!" I want to shout to them, and sometimes do, especially to the young ones, who like to pedal with their knees high and their pants low, spinning round and round, their legs never extending the way they should.
Yes, biking can make you fit, but if you don't fit your bike, you're asking for trouble. You lose power, invite fatigue, and can end your ride feeling sore and achy without realizing why. This spring, besides cleaning up your bike—checking the brakes, the spokes, the cables—pay attention to the fit.
