46X17. 71.1 G.I"s
Tried a few others from 44 to 48 but the 46 ring was just right.

I do my 10 mile commute in 27-33 minutes. My record is 25, but I had no backpack, lock or any extra weight at all that day.

39 x 14 on a 23mm tire. 73.3 GI.
I am looking to move up though, possibly 48 x 16 b/c I have both cog and chainring laying around. That would be 78.9. We'll see if it is too much of a jump.

I'm happiest in the mid 60's-low 70's. 68 is just about perfect.

main bike: 47 x 19 with 165mm cranks = 65 gear inches according to sheldon. purposely low to force myself to spin, and as an unintended consequence its truly a joy to ride. beater is about 81 gi. not nearly as fun...

42 x 16 on 700c/25mm = 69 g.i. according to Sheldon's calculator. It's probably lower than what most of my fellow flatlanders ride, but I'm looking forward to an improved spin next spring.

Another 69er here. My commute rises 360 m over about 7 km so it's nice going up and spinny going down. I do touch the front brake on the descent, but I'm hoping to improve my spin to the point where it's not necessary anymore.

76.5 looks like. Seems about right. I never seem to max out my speed.

approx 75" with a 172.5mm crank on clincher rims and 70" on tubular wheelset, same cranks. I prefer the 75 for going down hills and not having to touch the brakes.
For metro DC MD, which has it's share of short hill, repeated many times over, the 75 works fine. For those of you who are lucky enough to have REAL climbs 70" or even slightly lower might be better. Gerry
