Hand Grip Shifters

Some bicycles are now being equipped with a shifting mechanism called
Grip Shift, which is built into the handlebar grips and does not make use of
separate levers. The actuating mechanism is built into the inside part of the
grip that the web of the thumb and index finger closes around. To select a
lower gear, twist the right shifter toward you to engage a larger rear cog. You
can shift one gear at a time by moving the Grip Shift one click, or through
multiple gears by continued twisting. By twisting the left shifter forward or
away from you, a smaller chainwheel can be selected. To select a higher
gear, twist the right shifter forward or away from you to engage a smaller
rear cog. To engage a larger front chainwheel, twist the left shifter towards
you. Single shifts can be achieved by twisting one click at a time and
multiple shifts by larger twists.

Left hand lever Right hand lever
Most mountain style bicycles are equipped with shifters mounted on the
top of the handlebars and operated by the thumbs. To select a lower,
easier gear, shift to a bigger rear cog and a small chainwheel. Pull the left
shifter back to operate the derailleur. To select a higher, harder gear, shift
to a smaller rear cog and a larger chainwheel. Push the left shifter forward
fro the front, and pull the right lever back for the rear.

Below the Bar Shifters

Many mountain style bicycles now use a shift lever arrangement mounted
Left hand lever Right hand lever
on the underside of the handlebars, which use two levers operated by the
thumb and index finger. To select a lower gear push the larger (lower)
right shifter with your thumb to engage a larger rear cog. One firm push
shifts the chain one cog, continuing to push will move the chain over
multiple cogs. Pulling the smaller (upper) left shifter with your index finger
moves the chain from a larger to a smaller chainwheel. To select a higher
gear pull the smaller (upper) right lever with your index finger to engage a
smaller rear cog. Pushing the larger (lower) left lever with your thumb will
move the chain from a smaller to a larger chainwheel.
