OneUp V2 Carbon Handlebar (35 mm) & Sixpack Millennium Stem (35 mm)

The face plate is difficult to mount – is that normal?

Yes, this is normal with this combination.

The OneUp V2 Carbon Handlebar (35 mm) and the Sixpack Millennium Stem (35 mm) have a very precise fit. This ensures that the handlebar is absolutely secure later on, but the installation may feel tighter than with other combinations.

Why is the fit so tight?

The tight tolerance ensures:

• maximum grip of the handlebar
• no twisting under load
• even distribution of force on the clamping area
• This is technically intended, especially for carbon handlebars.

How do I properly mount the face plate?

• Position the handlebar cleanly in the stem
• Align the face plate
• Lightly screw in the screws by hand
• Press the handlebar down slightly into the stem
• Screw in the screws evenly in a cross pattern
• There may be a noticeable "settling" of the components during this process.

The face plate "does not sit properly" – what to do?

With this combination, it may happen that the face plate does not sit flat immediately.

Solution:

• Apply controlled pressure to push the handlebar into the clamp
• At the same time, tighten the screws evenly
• A slight "clicking" sound may occur and is not critical.

Can I apply more force?

Yes, but in a controlled manner and without misalignment.

Important:

• no one-sided load
• do not "pull the screws tight"
• components must remain properly aligned

What should I pay attention to when tightening finally?

• Always tighten screws in a cross pattern
• Maintain the specified torque
• Check for gaps

Important:

• Top side: no gap ("No Gap")
• Bottom side: a small gap is correct

Is this uncritical for carbon handlebars?

Yes, as long as the installation is done correctly:

• clean contact surfaces
• correct torque
• even clamping
• The tight fit is not a problem here, but part of the secure construction.

What to do if it still does not fit?

• Check the handlebar position again
• Completely loosen the screws and reposition
• If unsure, have the installation done by a professional dealer
