    Gear Chart

    You know how most gear charts are kind of confusing and hard to read, especially if your brain is fried from too much sprinting...

    Check this out:

    Brian,

    One small request: Is there any way that you can add 45/13 and 52/15 to the chart? Those are sort of common ratios by advanced racers. They make almost the exact same gear ratio, but the feel different. The 45/13 is used by sprinters and 52/15 by enduros. 45/13 feels "snappy" and 52/15 is good for cruising at speed. I can't really explain why, but they do feel different.

    Yea, no problem. The gear range was originally related to what I had in my gear bag.

    You can see the "one chainring tooth equals two inches" rule of thumb (this is what I used for the "nominal gearing") breaks down a bit across the full range... I hadn't thought of a 45/13 before; right between a 49/14 and a 48/14 which are common gears for me. Might have to experiment with that a bit.

    Thanks!

    It was random (and cool) meeting you today at the track! I'll see you Thursday or Friday for racing.
