ALWAYS TIGHTEN FASTENERS TO THE CORRECT TORQUE.
BOLTS THAT ARE TOO TIGHT CAN STRETCH AND DEFORM.
BOLTS THAT ARE TOO LOOSE CAN MOVE AND FATIGUE. EITHER
MISTAKE CAN LEAD TO A SUDDEN FAILURE OF THE BOLT,
CAUSING YOU TO LOSE CONTROL AND FALL.
WARNING
/27
The stem controls your handlebar alignment and must be tted correctly for
safe riding. The steerer tube and stem must be tight and exhibit no "play".
You can check this by loosening the bolts on the side of the stem (1) and
tightening the cap bolt (2) to pull the "stack" of steering bearings and spacers
together.
Do not over-tighten the cap bolt, but the stack of bearing and spacers on the
steerer tube should be tight. Ensure that the stem is aligned with the front
wheel (3).
Once aligned, re-tighten the stem bolts that clamp the steerer tube (1). Now
check alignment and angle of the handlebars and then tighten handlebar
clamp bolts (2). All bolts on the stem should be torqued to 7 NM.
