    What is your common gear ratio on flat road?

    On 53/39T rear with 11-25T rear,

    my most common ratio is either:
    53/15 = 3.53 (6th)
    53/14 = 3.79 (7th)

    Although my cadence is not very fast.

    Terminology suggestion: Rather than express those as ratios, or gear-sequence numbers, it is more common, and more understandable to road cyclists, to use something called "gear inches," which is the diameter of an equivalent direct-drive wheel. Divide ring teeth by cog teeth, and multiply times wheel diameter in inches (about 26.3 inches for the common 700/23C wheel size).

    So your 53x15 is about 93 inches, 53x16 about 87 inches.

    Unless you're a very strong rider who goes quite fast, those are big gears, and you are correct that your cadence is slow. For example, if you are going 18 mph with the 53x16, you're turning about 70 rpm. You might try using some lower gears and see if you can get used to spinning a little faster. It works better for most riders. In a 53x21 gear at 18 mph, you'd be at 90 rpm.

    I have no idea.

    Do people really look back to see what gear they are using and keep track of it?

    Of course on this forum the expected answer will always be: 53 x 11!

    The one that feels right for me at the time.

    I'm comfortable riding my fixie, with 42x16, all day long on flat roads.

    I like 80-85 gear inches on a flat road. My single speed bike has 48:16 (about 79 gear inches).

    On a 50/36 with 11ó23, I usually ride at 50/17 or 50/18. No idea how fast I'm going since I don't have a computer yet.

    Really?

    I knew that roadies are an insecure bunch, but I didn't realize that people felt the need to compare gear inches.

    Lots of variables but assuming little to no wind in your face I tend to settle into 50/16, 50/17 around 78-83 gear inches.

    I havenít really paid attention to that but now that Iím thinking about it, I guess I am probably in the mid 70ís, maybe the low 70ís actually Ė yeah, Iím gonna go with low 70ís. Thatís a solo cruising speed (comfortable but not beach cruiser effort) on flat ground with little wind. Probably seems slow to all you Interweb strongmen but also know that I like to spin so as not to put too much stress on my delicate and oh so supple walking appendages.

    And anyone who thinks it too slow, I got a finger to show you.

    I run 71 gear inches on the fixie and when on flats with the geared bike I'll settle into 77 gear inches. On the geared bike I can always downshift if the wind picks up. On the fixie I run a little less gear for the reserve it offers for strong head winds.

    Dead calm maybe 50/17. But it's almost never absolutely flat or dead calm here.

    I always start in the 53/21 (67") and then shift to 53/19 (74"). I like a lite, fast cadence.

    Between 70"-80" depending on winds, etc. usually 52x19 or 52x17 if I'm feeling frisky.

    Depends on the ride. I seem to average around 65.2 inches which is the equivalent of a 46/19 which is incidentally the most used gear on my bike. When I started riding I averaged 75 inches but my cadence has increased drastically.

    Probably 50/19 or 17 if I'm just riding along without any wind. Wind is usually in pretty ample supply though.

    No idea, but I know it is not flat enough that I ride around in a 53 anything very much.

    When I was riding only a singlespeed road bike, I found a 53x16 was best for flat rides.
