BEFORE YOU RIDE
Thumb shifters (Top Mounted)
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
for 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
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.
