Use a specialized internal routing tool or a thin fishing line to pull the E-Tube wires through the exit ports.

Pros and Cons

Pros

  • Clean aesthetic thanks to internal Di2 cable routing
  • Lightweight carbon fiber construction reduces fatigue
  • Ergonomic drop design enhances comfort during long-distance riding

Cons

  • Requires adjustment to wider hand positioning in the drops
  • Carbon bars require specific torque settings for installation

Setup, Compatibility & Care

For installation, ensure you are using a stem compatible with a 31.8mm clamp diameter. When attaching the handlebars to the stem or mounting components like shifters, always use a calibrated torque wrench to stay within the manufacturer's specified limits for carbon components to prevent structural damage. To protect the carbon fiber finish, avoid sharp clamping surfaces. For maintenance, clean the bar periodically with a soft cloth and mild soapy water, avoiding harsh degreasers that might affect the clear coat. Inspect the surface for any signs of cracking or deep abrasions after significant impacts.
