Notes:
* Apply grease to the thread seclion of lhe bottom brackel and to the inside
thread of the adapter before installing the bottom bracket.
» Use an outer casing which still has some length to spare even when lhe
handlebars are turned all the way to both sides. Furthermore, check that the
shifting lever does not touch the bicycle frame when the handlebars are turned
all the way.
* Because the high cable resistance of a frame with internal cable routing would
impair the SIS function, this type of frame should not be used.
