what's your commuting gear ratio?

what's your favorite gear? I'm just interested after turning my old Univega into a SS. I'm running 42-18 and thinking of changing to 42-20... or even 22. I like spinning! Tempe has no hills so that's not a consideration.

When I convert my Stumpjumper, I'm likely going with a 46-18 combo. Right now I spend most of my time hopping between the 17 and 19 cogs, with the front staying mostly on the 46 ring. That gives me a comfortable spin cadence at 14.5-16.5mph (46-19) and 16.5-19mph (46-17).

39:17 (62") is my ratio, close to your 42:18. I love it: it's great for stop and go in traffic and the short hills in here. Avg speed is 22 kph @ 73 rpm.

After a year at 39:15 (70") I'm really happy I changed. No difference in avg speed but cadence went up 15%.

But gearing is about preference. Try that 42:22 and let us know! I love spinning as well. If you say its flat I would think its a bit low: at 42x22 your speed at 90rpm is around 22kph.

I like 48/17 just fine. I run fixed. When its single speed, its 48/18.

My commute is all hills, up and down both ways. I'm constantly going up and down the cassette and switching between the large and small chainring.

I run 52:19 on most of my commute although its starting to feel like I'm spinning too much with that ratio. I'm starting to gradually use 52:17 now on the flats but its going to get a lot of getting used to.

43 x 15 (75 g.i.). I'd had it set up with 42 x 16 (69 g.i.) which was great for in town, but a bit low for the open road. With the nicer weather and a chance to take some long rural detours on the way to work, I went with the higher gear. I'll probably go back down again when it starts raining again.

I’m a 46/18 (69”) SS. I like to spin 85-95+ and that gives me my 18-20 mph (my goal)

currently 48/17, though I'm starting to think it's a little short.

Summer - on 25mm slicks - 42/16
Winter - on 35mm Nokian studs - 39/17

Pretty flat around here, wind is my only nemesis. This is SS not fixed.

Looking at this thread, I might be odd for running my SS at 36x14 (66"). But then, mine is a 26" an not a 700c.

Hoping to add an SS beater bike to the stable in the coming months, and I often do my commute in a single gear, in "training" so to speak. Last time I did so was last night and this morning, and I was running 52x19. I think my SS will be set up something like 42x16 or so.

50/19 fixed, works well on the hills here but I don't really spin out on the downhills.

I am spinning away currently on the small ring at the moment 42x15(16) mostly. With age, I don't seem to have the energy to chomp at the big ring. Some weeks I have it, and some I don't. Some weeks I have a little help from the wind, and then I can get some sweet 53x13 action.

On my Roadie 42/17 is the gear I am in most commonly. On my Fixed gear bike, it's a 44/17. Probably gonna drop it to 41/17.

48x18 on the fixed, though the route from the girlfriend's house is hilly enough that I haven't ridden it fixed (yet?)....

I'm running a 42-21 on my SS road bike (only bike I own). Like you, I like spinning. The area I live in is pretty hilly though. On the flats I average anywhere between 100 and 120 rpm depending on the wind direction. The lower gearing is very nice for the hills.

gear ratio

42/16 on 700/25 on the fixie/commuter. fast enough for my commute, but not too killer on the hills.

good luck!
