I run 46:17 on my fixie, soon to be 46:19 (moving somewhere hilly). 2:1 is rarely an appropriate ratio, on or off road. If you swing over to the MTBR SS board, you'll see most of them running 32:18/19/22 or something along those lines. They think 2:1 is steep. And most fixed gear road rides think it's way too small, which I agree with.
46 Chainring, I have 13 thru 20 tooth cogs depending on my mood & training intentions that week. I've been running an 18 & 20 lately to work on spinning & that's been a lot of fun. I haven't changed the speed of my training, just increased the spinning, up to 165 to 170 cadence on the flats.
Chicago may be flat, but I've forsaken my masher ways. Plus it is my first fixed so I kind of just took a shot in the dark on the gears.
Can we just make this thread sticky? seems like a common question
42x14 right now. 700c. 175mm cranks. i only ever rode in one gear on my geared bike so i just picked whatever that ratio was when i built my fix.
but i'm thinking of making it 43x14 so i have more than 1 skid patch.
