Never did ride in "aero" position. Never wanted to.

Now, it's upright and used for commuting and leisure.

Was extremely fit (great cardio, very strong, flexible) up through the mid-90s or so. Fitness began to give way to coping with and focusing on old injuries, and what exercise I could accomplish. About 2005, I began to raise the stem and the bars. In 2014, I got an adjustable stem and even taller bars. Now, it's 5" riser swept bars and a nearly-upright riding position, with a shorter top tube, wider Brooks saddle. The past 20 years have been a change from modestly-athletic (posture 3/performance) riding position to one that's upright. Pretty much tracks the injury condition and ability to manage it.

Sign of the times.
