WILIER ZERO SLR / SL MANICOTTO PER CAVI PVC BLACK Type 2

Core Application: It serves as a specialized internal guide and friction/noise buffer inside the carbon frame. It isolates internal cables, brake housings, or electronic drivetrain wiring (such as Shimano Di2 or SRAM eTap AXS) as they pass through complex entry or exit ports in the frame, protecting them from structural wear or interior rattling.
