The Tyee 6.1 AL Enduro offers three cable routing options:

• Sixpack ICR: Cables routed through the upper spacer and headset into the frame. Compatible with Millenium ICR stem (35 mm or 50 mm). The cleanest, completely noise-free cockpit solution.
• Standard ICR: Cables routed through the top cap. Compatible with Vertic or Millenium stem. Also a very clean setup.
• Classic Internal Cable Routing: Cables routed through Propain's own cable ports behind the head tube. The self-sealing ports clamp and seal the cables and remain closed even without cables.
