I have 700x35C tires. The manual seems to say to set the circumference at 2205. It was not written with English as the primary language, and leaves much to be desired.
I went on a ride with someone else, and her computer said we went 5.68 miles while mine says 8.85. My phone GPS more closely confirms her number (5.4 mi).
I went poking around the Internet to find the real circumference, and found two numbers: 1370 and 2168. Just doing a ratio between what my GPS stated and the the numbers on my odometer, I think the 1370 number is more accurate.
I am not looking for 100% accuracy, just something closer than 3 miles off. What number has anyone else used in this setup?
