Headset stem:
All MTBs fitted with aheadset stems are sold with setting rings. The
handlebar height suggested in the shop is the highest. If you would prefer to raise the handlebar position, you will need to
choose a higher stem.
Adjusting aheadset stems on your bicycle:
To reduce the height you need to use appropriate tools (T-bars 5 or 6 depending on the model - see tools chapter).
- Completely unscrew screw A, then the two B screws in the stem.
- Remove the stem.
- Take 1 or more setting rings.
- Replace the stem.
- Replace the setting rings above the stem.
- Tighten up screw A and tighten the B screws.
Checking that aheadset stems are properly fitted to your bicycle:
To check the adjustment of your stem, close the front brake and rock forwards and backwards on
your bicycle.
If you feel any movement in the steering system, tighten up screw A.
Second check: lift the front of the bicycle off the ground and turn the handlebars from side to
side.
If it's hard to turn the handlebars, unscrew the screw A.
If this procedure seems too complex, please ask the staff in the workshop at your nearest shop.
Checking that the handlebars are properly mounted in the stem.
On Elops (1, 3, 5 and 7), b’Twin Pack and BMX bicycles, the handlebars are set at a significant angle. The angular position of the
handlebars should not be modified by more than 10° compared with the assembly position (see pictures below).
• Adjusting the seat post and seat: check that the whole bicycle is solidly assembled and that the seat is solidly clamped in the frame, respecting the
minimum insertion point indicated on the tube.
• Tightening the stem: before each use, check that the stem is properly adjusted using appropriate tools (see tools chapter) and tighten to the torque
indicated. Check the value in the stem/steering system torque table.
• Tyre inflation, dimensions and mounting direction: inflate your tyres to the correct pressure, referring to the pressure range indicated on the side of
the tyre by the manufacturer; your tyre’s resistance to wear depends on it. Mount the tyre in the direction indicated on the side (the arrows indicating
the rotation direction).
• The assembly and tightening screws should be tightening according to the recommended torque settings. A screw or nut that is too tight may
elongate and lose its shape. A screw or nut that is not tight enough may move and wear out through fatigue. In both cases, this may cause the screw
or nut to break suddenly, resulting in a loss of control and the user falling.
• WARNING: Insufficient tightening of the screws between the stem and the fork, the handlebar tightening screws or the screws fastening the
handlebar extensions, may compromise the steering and lead to a loss of control and the user falling. Put the wheel between your legs and your
hands on the grips. Try to twist the entire handlebar/stem assembly around the axis of the fork. If this handlebar/stem assembly moves while the
wheel remains stationary or if the handlebar extensions turn around the handlebars, the fastening screws are not sufficiently tightened.
