Does wheel size affect gear?

There are many myths that people are told about why smaller wheels are slower than bigger ones. All of these theories, while having some truth in them, ignore several other aspects of the differences. Those differences compensate for the reasoning used by sellers in shops to make shorter-height riders purchase the bigger and more expensive wheels. In fact wheel size has nothing to do with speed. A road bike with 26-inch wheels is geared to ride at the same pace as a bike with 700c wheels. The answer is situated in gear inches. Gear inches is a system of measuring the corresponding number of inches moved forward per crank rotation.
