The
Shimano Rapid Fire Plus shifters
(e.g.
XTR model 2007) work according to the usual
Rapid Fire principle (see above), but in addi-
tion the small lever (the index finger lever)
can be used with the thumb too. Using the
thumb leads to the same shifting action like
using the index finger. The chain runs to the
small chainwheels and sprockets.
So you can shift by thumb and index finger or
use the thumb only.
0. The gears
Furthermore, you can shift more than one
gear by one move: A short shifter travel
results in a one gear change, a long shifter
travel leads to a double gear jump.
With the
Shimano Dual Control gear and
brake lever
components, the brake lever has
to be pushed downward to shift to the smaller
sprockets at the rear or to shift to the bigger
chainwheels at the front. This will give you a
higher gear.
Pushing the brake lever upward or pushing
the optional small lever, located under the
handlebar, with the thumb, will give you a
bigger sprocket at the rear or a smaller chain-
wheel at the front, both leading to a smaller
transmission.
