Dual Control Shifters
The majority of drop bar road bicycles produced today are fitted with dual control levers.
Since both the brakes and the gears are built into the one mechanism, dual control
shifters make it possible to change gears without having to remove your hands from the
handlebars. Shifting can be performed whilst your hands are resting on the lower bend
of the handlebars or on the brake lever hoods (in the “drops”). Pulling the shifter towards
the bar activates the brakes, while shifting the dual control lever in towards the front wheel
engages the gears. To select a higher gear, the small right lever is pushed to engage
a smaller, rear cog. Pushing the large lever inwards activates the large, front chainwheel.
To select a lower gear, shift the large right lever inward to engage a larger rear cog.
One firm push shifts the chain one cog, while continuing to press will move the chain
over multiple cogs.
