💬 FAQs
Is the Nexum Drag compatible with my frame?
Yes — it’s designed for standard 1-1/8″ steerers and can be customised for ACR, D-shaped, or other integrated headset systems. Contact us if you’re unsure about your setup.
What’s the difference between the Nexum and Nexum Drag?
The Nexum Drag is the aerodynamic version, featuring a flatter top section, improved stiffness, and reduced drag — ideal for performance road and gravel builds.
Can I customise dimensions and finish?
Absolutely. Choose your preferred handlebar width, stem length, angle, carbon weave, flare, and finish. Even the logo colour can be customised.
Does it support Di2 or mechanical groupsets?
Yes — it supports both, with options for internal or semi-internal routing through the bar and stem.
How should I install it?
Use a high-quality carbon paste and a torque wrench. Maximum 4 Nm on steerer and lever clamps. If unsure, have it installed by a professional workshop.
What’s the warranty?
2-year manufacturer warranty from Darimo Carbon, covering defects in materials and workmanship. Every cockpit is handmade and inspected in Spain.
🔥 Why Riders Choose the Nexum Drag
