Caution: The handlebar stem is an A-head stem, the top screw
E is preloaded with 1-2 Nm and does not adjust the handlebar
stem. Trying to tighten bolt E can damage the head set bearings.
Failure to correctly secure the handle bar and bar stem can
result in serious or fatal injury. Ensure there is no play in the steering
and that the steering is working smoothly. Should you need further
advice to adjust the headset, please contact your A2B dealer.
