Gear Inches- The descriptions above refer to gear inches for comparison purposes. The term refers to the effective equivalent wheel diameter per pedal stroke. For example, if you're pedaling the Divide Pinion in first gear, each full pedal stroke will produce the equivalent of one wheel revolution of a 17" wheel, while the highest gear will produce the equivalent rotation of a 108.1" wheel.
