I've always got a tender lower back. I exercise 5-7 days a week. Ride a road bike with flat bars. Up to now I've always set my seat height by the old method of putting your heel on the pedal with leg just slightly bent.

Just lately I'm watching around and a lot of commuters can touch the ground while sitting on the seat. I've also read somewhere that if the seat is too high your hips have to oscillate as you pedal.

With these thoughts, I'm going to lower my seat by 2 inches for a while and try it. An auxiliary benefit of this will be relatively higher bars and that will also be more comfortable for my back.

Has anyone else tried this already or found it good or bad?
