The handlebars should come attached to the stem.
Simply ensure that the brake and derailleur cables track
smoothly, and that the handlebar bolt(s) are properly
tightened with (C) a 4, 5, or 6 mm Allen Wrench. (See
Figures 23-25). In the case of a 2 or 4-bolt stem, tighten
the bolts alternating between bolts every few turns. We
will adjust the position and rotation of the handlebars,
brake levers, and shifters later on (see page 35).
