PRO Headset - Ahead | Tapered | for Internal Cable Routing - IS52/28.6 | IS52/40

This headset from PRO not only enables clean and convenient, but also seamless and aerodynamically advantageous internal routing of hydraulic brake hoses and electronic cables (including Shimano Di2). The Ahead headset achieves a particularly tidy aesthetic in combination with handlebars, stems and integrated cockpits from the Vibe series, for which it was specially developed.

In addition to the resistant stainless steel bearings, the rubber seals and plugs, which protect against the ingress of water and moisture, are also dedicated to durability and longevity. While the round bearing cover ensures compatibility with most frames, the micro spacers allow easy height adjustment for precise adaptation to the respective bike model.
