/\ WARNING
It is important to completely understand the operation of your bicycle's
brake system. Improper use of your bicycle's brake system may result
in a loss of control or an accident, which could lead to severe injury.
Because each bicycle may handle differently, be sure to learn the
proper braking technique {including brake lever pressure and bicycle
control characteristics) and operation of your bicycle. This can be
done by consulting your professional bicycle dealer and the bicycle's
owners manual, and by practicing your riding and braking technique.
The M570 brake system is equipped with a power adjuster in the wire
hooking unit of the ST-M570/BL-M570 brake lever which allows the
rider to change the relationship between the brake input and output. If
this power adjuster is moved, the braking force will be dramatically
increased, so that a high level of braking performance can be
achieved from only a small amount of lever movement. Accordingly,
normal braking operation may cause a greater-than-expected amount
of braking force to be applied, which could make the bicycle fall
forward, causing serious injury to the rider. To avoid this, please read
the following instructions thoroughly before moving the power adjuster.
After changing the power adjuster setting, make
sure that you are completely used to the new
braking characteristics before riding the bicycle,
otherwise the bicycle might fall forward if you
have to apply the brakes suddenly, such as when
a vehicle appears.
1) Without power adjuster being moved (standard
specifications for shipment)
Power adjuster
2) With the power adjuster moved to the position shown
in the figure below
An ample degree of braking force can be obtained from a small
amount of brake lever input, to provide a high level of brake
performance. However, if the brakes are operated suddenly with a
normal amount of brake lever input, there is the danger that the
bicycle may fall forward. After moving the power adjuster, first ride
the bicycle at a speed of less than 6 mph (10 km/h) while applying
the brakes repeatedly in order to get a feel for the difference in
braking characteristics before riding at higher speeds. Beginners
should be particularty careful.
When the power adjuster is moved from the middle position to the
position closest to the handlebar, the braking force will be even
more sensitive to the amount of lever input. Beginners or those
who are not fully confident should not use the brakes in this
configuration.
