This poll is specifically for fixed-gear bikes that are mainly ridden on roads. Freewheeling, and off-road use, throw in other major variables that I don't want this poll to have to deal with. (Of course, there are other variables, such as the terrain in which someone rides, and the cadence that they like to spin. A bigger gear doesn't necessarily mean that someone is a stronger cyclist. But, on average, it does.)

Gear inches takes your wheel size and gear ratio (e.g., 42/15) into account. Basically, gear inches measures your gear as if it were equivalent to the size of a high-wheeled bicycle. It's your gear ratio multiplied by the diameter of your rear wheel.
To calculate yourself:
(rear wheel's diameter at outside of tire) * (# chainring teeth) / (# teeth on cog)
So for my bike, with 27x1 1/4 tires (27.075" outside diameter), and a 40/15 chainring/cog combination, the gear inches is 72.2.
You can also use Sheldon's calculator to figure out your bike's gear inches.
Make sure to set the standard to "gear inches" not "gain ratio" which takes cranklength into account.

Note that the categories of the poll are endpoints. So, 71.1 would go in the "71-74" category, not in the 68-71 category. If you have an exact number (unlikely) go to the larger category.

If you have multiple fixed-gear bikes, or a flip-flop double-fixed hub, vote for the bike or gear that you use most frequently.

80.3 soon to be around 75.

71.8 but its hilly here and im still recovering from a leg fracture.

queerpunk

75.6. all-purpose.

spud

84.1 apparently

46x17

My 47x17 is 72.9 according to SB.

I'm currently stuck with either 82.9 or 66.9 with the cog and rings I have on hand. I have parts in the mail hopefully arriving today or tomorrow that will let me run at about 74 or 75 depending on tire size.

(warning: shameless plug ahead)

check out the gearing calculator I'm putting together that is tailored specifically for SS/FG applications. It helps you find gear combinations in a bunch of different ways and also calculates how many skid patches each gear ratio has.

i recently went from 78.8 (48x16) to 74.2 (48x17) and i love it! much better for riding around the city in traffic. i feel quite zippy

jamey

49x17 and it gives me 75.7 gear inches. i think it's the perfect ratio for around town.

drac_vamp

50x16 (700cx23) somewhere floating below 82. sanfrancisco has its hills.

isotopesope

my bianchi is 48:16 for street, 48:14 for track, running 23c tires. my peugeot fixie conversion is 40:15 with 27"x1.25" tires.

jim-bob

38x15x26", 43x16x650c, 42x16x700c.

You'll see a trend there.

recursive

48x15. Stock ratio on the Raleigh Rush Hour.

Fantomas

45x15 on 700c 24-7
**** hills, they are everywhere here.. you get used to it

Accident

81.0 48x16 165mm
hilly around here so we gta bust ass to get around

evanyc

odd dip in the 77-81 range, especially considering i thought 48x16 was one of the most popular combos here

queerpunk

i like to say this when gearing comes up.

lots of people qualify what they're riding by mentioning hills, as if they need to give a reason why their gearing is low (if indeed it is). it's similar to the FGG "i have a brake but don't use it"/"for the hills" phenomenon.

just ride what you ride. don't worry that somebody might think you're a pansy if you ride 69" with a brake. anybody who would think that is probably a dip****.

hyperRevue

Just went from 81 (46x15) to 76 (49x17) on my main bike.
The other is 79 (48x16)

muftek

oops, i voted one category too low. 77.42" here. sometimes i wish it was a tad higher, other times i dont. oh well.

crushkilldstroy

i always think the exact same thing. i choose my gearing because it feels right, not because of what some random dude across the country thinks.

i run 70.4 on one of my bikes and 69.3 on 2 of em. one of them is biopace. i like to spin. somebody please come and burn down my house.

I was ridding a 700c35mm tires with a 34x14(66.0) which was great for the C&O Canal, and I was able to do a normal route, but a little slow for Washington DC, and anything pruely flat. I went to a 38x15(68.8) and I like the speed of the gear, but it was not working on a normal route that included some up hills, so I am torn about what to ride, I can go with the 38x15 (I road to work today) and pick special routes that are flat, or the 34x14 and have more choices but a little slower. I am thinkning slower, cause if I want speed I have other bikes.

And all this time I thought it was a direct corrolation to the size of my penis. *SIGH*.

crushkilldstroy

well, it is. but that's a subject for a different post.
