Gear Shifting Components
Before we go into detail about how to shift gears on your
Mountain Bike, it should be first explained what the Mountain Bike
Gear Shifting System Components are. This to give you an idea what
happens technically if you shift gears; if you understand how the
gears work, shifting gears will be something that comes natural
instead of a thing that you should memorize.
The crank which is bolted onto the bottom bracket
consists of three chain-rings. Chain Rings are bolted into the
cranks. They come in three size ranges. The big ring (48-42
teeth), the middle ring (36-32 teeth), and the small or
"granny ring" (26-20 teeth).
The "sprockets" or "cogs" are found in the
rear hub. Modern sprockets consist of 7-9 size ranges from 36-11
teeth. Normally, the 7 & 9 speed sprockets have the same heavy
and light gear. The difference is in the mid-range gears. The
9-speed sprocket has more mid-range speed which lessens the change
in speed upon up or down shift.
