|  Going 29" for 2004, how to calculate gear ratio | IbisBreezer
Jan 13, 2004 1:35 PM | | What is the equivalent cog combination for 29-inch wheels that will emulate the 34-18 I am currently running with my 26-inch bike.
Huh?
Thanx. |

Jan 13, 2004 2:16 PM | | The formula is...
front / rear * wheelsize
For example,
34 / 18 * 26 = 49.11111111111111111088 gear inches |
| yeah aosty's got it, why guess or estimate, be exact nm | club

| Simple! When going from 26" to 29", drop it by 10% | GlowBoy
Jan 13, 2004 7:15 PM | | That's about 2 teeth bigger in back, or 3-4 teeth smaller in front. |
