FixMeUp! Instructions continued: interpreting the results

Below is a picture of the Java 1.0.2 version of FixMeUp!. I'll describe reading the display using this picture. While other versions of FixMeUp! look slightly different, you'll have no trouble applying what you read here to using those versions.

The numbers along the top of the chart tell you that the chart shows gears for chainstays ranging from 16.00" to about 16.25". And the numbers along the left margin indicate that gears ranging from 80" down to about 55" are displayed. To change the range of gear inches shown you need only scroll the chart using the scrollbar. To change the chainstay, enter a new value in the chainstay field and click on the "Apply" button.

The label above the middle vertical line is the length of the chainstay the chart was generated for. The gears closest to the middle line are the one's we're interested in.

The light blue highlight area gives FixMeUp!'s guess at the range of gears that will fit on a frame with the chainstay length for which the chart was drawn. The area shown above is for a frame with vertical dropouts using a standard axle. With a horizontal axle the area is several times wider than the chart; with a Fixed Innovations axle it's about four times the width you see here.

The gears you can use in your frame -- assuming all the inputs are correct! -- are those with their left edges in the blue area. In this case, that means 40x14, 42x16 and 44x18. And maybe a few others in the part of the chart that's scrolled out of view above or below.

The purple region at the lower left of FixMeUp!'s display gives detailed information about whatever gear is selected (the 42x16 in the middle of the chart, in this case.) The location of this detail area is one thing that differs among the various FixMeUp! versions; in some it's in a separate dialog.
