Gearing for fixed-gear spinning bike?(3 posts)

Gearing for fixed-gear spinning bike?Qubeley
Jun 2, 2002 6:02 PM
I finally got myself a fixie last month, F/R breaks since I am not good at all the tricks, had about 100 miles on it, I love it!
There are a few things I am curious about:
what gearing do you use? I have 38-16 right now.
How do you divide your time between the fixie and the road bike?
I wonder, knowing your gear-ratio, can you tell your cadence based on speed you are travelling at? anybody have a chart or know a source? Thanks!

I put a few miles on my fixie this weekend too. Both of my "geared" bikes were sick. I ride a 42/15 with 27" wheels, gearing can vary widely depending upon your local terrain (I live in the Texas Hill Country and have hell descending sometimes). I can't seem to "comfortably" spin much above 140rpm with the 170mm cranks. There's an online speed from cadence calculator at: http://www.analyticcycling.com/GearSpeedCadence_Page.html

FWIW, It seems pretty acurate.

Awesome!
Now I know when I climb at 10mph in my 39-21, I have a cadence of 70rpm; and when I rode my fixie with my ride pal today reaching 31mph, I was pedalling at 166rpm; when I sprint at 40mph in 53-14/13, I am around 130rpm.
Thanks a lot!
