    "The Siskiyou rides soooo smooth! It’s an amazing descender, the geometry working with the big tires to give huge confidence. If the test of a bike is how much you choose to ride it over other bikes, the Siskiyou is a success." Dave.

    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.
