Mountain bike gears are an essential part of any quality mountain bike. The whole point of a mountain bike is to be able to go wherever you want; uphill, downhill, paved or dirt. The bike gears are what make this kind of versatility possible.
Mountain bike gears come in many configurations. Gone are the days of the typical 10-speed bike, as many of today’s mountain bikes can have as many as 27 gears. Serious competition riders often customize their gears in order to maximize their particular abilities.
Mountain bike gears operate through a series of sprockets on both the rear wheel and the cranks. The sprockets on the cranks are typically larger than those on the rear wheel, as they are the driving force. Generally speaking, there will be 2-3 sprockets on the cranks and as many as 9 sprockets on the rear wheel.
