S-DCR model is an Integrated headset compatible with DCR
system (Deda internal cable routing) that allows the direct cable
routing into the topcover. This solution makes any Deda stems
fitting a DCR frame, a quick and smart solution for most of bicycle
brands. It allows the full integration of the cables ,like the DCR
headset, but leaving a portion of the cables visible under the stem.
The system works with a standard tapered fork steerer (1-1/8” - 1.5”)
and requires a 52mm (1.5”) upper headset bearing od. The special
compression ring design leaves room for the cables to fit the gap
in between the headset bearing and the fork. The S-DCR headset is
also compatible with Deda HSS spacers for a better integration.
