Quick Poll–What gear combo are you using, and how many gear inches are you pushing? See http://www.sheldonbrown.com/gears/ for a gear inch calculator.
I’m running a 46X18 on 700X28s with 170mm cranks for a 68.4 gear inch total.
It feels pretty stiff to me, but I wonder what the ‘hard core’ guys out there run.
42/17. I wanted to be able to climb the hills around the rose bowl. 170mm. 700x23
34/14 or 15. 165 cranks, 700x31 cross tires.
44x16 on 650x20’s. Whatever that works out to…
I ride my fixed-gear for commuting in Chicago - very flat and sometimes windy.
700x35 tires, 175 cranks
48x18 72-inch for winter (really have to push into a head wind; really have to spin with a tail wind)
46x16 78-inch for summer (kinda big, but I like to keep up with the impromptu pace lines that sometimes form on the lake front path)
I time trial and do my AT intervals between 90-96 inch gear. When I just putz around on the fixe, I usually am mid 70s ish. I generally try to keep my cadence around 100. It is much easier with 165 cranks as well. G
during the winter when I’m riding on the roads I run a 46 X 17. It’s pretty hilly here in socal and I like that gear a lot. During the summer when I’m on the velodrome I’m running a 48 X 14 thinking about going to 49 tho. 71 and 90.1 gear inches respectively.
I use 39 X 16 with 170mm that’ll will get me up and around most routes here in Upstate NY.
42x16, 700c wheels, 170mm cranks. Very hilly in these parts.
48/16 came on my Pista, but that is to high for anything but putting around town with. Maybe if I got a higher gear, I would ride the damn thing a bit more. As it is, decelerating is a knee killer.
700c X 23 tire with 172.5 mm cranks
Fixed gear: 42 x 16 = 69.0 gear inches

69 inches for my fixe trainer in hilly Seattle (700c, 172.5 - I have 170s on my actual track bike.)
.
45/18, 170mm cranks, 700c. Hilly here, it seems to be okay for the most part, haven’t had to get off and walk…yet.
42/17 for me. I use the fix for recovery and high cadence work, as well as making it my town bike.
I typically run around 69 gear inches for general commuting around the hilly Vancouver area. It’s enough to be bitch-ass hard on the steepest hills, and “I can barely hold this cadence” on the descents.
I switched to a 73 for a while after I raced it in Olver, but it was too much coming up the steeps from Kits pool. (Of course I’m not bright enough to find an alternate route, either 
)
69 is good for commuting, recovery rides, and general tooling around.
