Built for riders who prefer the flexibility of semi-internal (under the stem) routing, our Headsets for Semi-Internal Routing were developed for frames using an EC44 headset. These headsets are equipped with a custom seal at the cable entry ports that eliminates contamination from moisture and debris, maximizing bearing life.
