In the city I ride in the relaxed hood (arms almost straight) or aero hood position (meaning my elbows are angled at roughly 90 degrees) for the most part as shifting and breaking is easier for me on the tops.
Once I am out of the city, I ride the drops when it is close to flat and in an aero position in the hoods when I climb. I only use the “relaxed” position when I am doing very long, sustained climbs (think >20 minutes) or selectively when it gets very, very steep.
I didn’t know all this when the bike was fitted to me last year, because this was my first road bike in about 10 years.
