A 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 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.
In order to realize the best performance, we recommend that the following
combination be used.

transmission of force decreases and the return of the arch is poor, turn the
sleeve 180° as shown in the illustration, so as to increase the spring force.
Note, however, that brake levers other than the SUPER SLR cannot be used,
even though the spring force is increased.
