Internal Cable Routing Headset 

A brief look at FIRST's new All-Aluminum (no plastic spacers) Integrated Cable Routing Headset. The key component is the top cap which is specifically machined to fit the particular stem it's designed for. The model here is designed to fit an FSA integrated stem and handlebar.
We demo the process of installing the headset to give you a general idea of how it would look. We did not have the FSA stem to demo a tight integration between the headset and the stem. But you get an idea of how it works. FIRST COMPONENTS is primarily an OEM (Original Equipment Manufacturer) and ODM (Original Design Manufacturer). This internal cable routing headset is offered on an OEM/ODM basis to brands wishing to produce their own branded design of headset.
