What it's supposed to look like. I'm posting to this old thread to provide something I can refer to in the future.
I finally got around to taking some photos of me on our tandem. I'm showing this bike because it's an all-purpose bike for fast rides, touring, and long distance. Ignore the position of my right arm, as I'm using it to hold myself upright. I'm showing moderate, all-day positions:
captains_comp.jpg - shows captain's compartment. Bar tops are 1.25" below saddle. My singles for long distance have the bars a couple inches lower than this. Note how the start of the hoods forms a continuation of the flat portion of the bar before the bend.
standard_hoods.jpg - shows normal cruise position with leg extended. Note foot is flat or heel slightly dropped, bent elbows, angle of back and knee, little finger behind bar.
low_standard_hoods.jpg - shows position for slightly faster riding. Note relationship between elbow and knee, almost level forearms, little finger behind bar.
low_modified_hoods.jpg - I spend a lot of time in this position. Note forearms again near level, two small fingers wrapped around bottom of hoods, fore and middle fingers and thumb wrapped around top of hood, wrist resting on bar top, elbow in front of knee. Stem could be 1 cm longer - this gap is minimum.
standard_drops.jpg - shows normal position for riding in the drops. Note elbow in front of knee, angle of back similar to low_modified_hoods.jpg. The low hoods position is a little bit faster, but one has better braking, handling, and faster acceleration from the drops, plus it's a nice change. I descend in the drops.
standard_climbing_tops.jpg - just like it says. My normal climbing position. Opens the chest. Note amount of elbow/knee overlap, angle of back about the same as standard_hoods.jpg.
fast_climbing_tops.jpg - shows position for climbing upwind or climbing accelerations. Again note elbow/knee overlap.
These are not racing positions. This is my touring bike. These positions are very comfortable for my aging back, arms, hands, butt, etc. There are many more hand positions available on drop bars, but the ones shown are the main ones. My legs are short and these cranks are 172.5, so your legs may not look exactly like mine in these same positions, but elbow/knee relationship should be similar.
