Restore or upgrade your RockShox Lyrik D1+ fork with this genuine OEM Crown Steerer Unit (CSU). The CSU is the upper structural assembly of the fork — comprising the crown, steerer tube, and upper stanchion clamps — and is the correct replacement part when the steerer or crown is damaged, or when rebuilding a fork to a higher specification. This unit carries the DebonAir designation and suits 27.5" or 29" wheel builds with a 44mm offset.

  • Genuine RockShox OEM Crown Steerer Unit (CSU) for the Lyrik D1+ (2023 onward)
  • 44mm fork offset for the Lyrik's intended trail and enduro geometry
  • 69mm OD steerer with 1.8° taper for use with tapered headsets
  • DebonAir air spring compatibility — correct crown porting for DebonAir positive chamber
  • Diffusion Black anodised finish; no gradient graphics
  • Suits both 27.5" and 29" wheel builds

The CSU determines fork offset (and therefore trail and handling character), steerer diameter, and the alignment of stanchions relative to the crown. Using a genuine RockShox CSU ensures correct stanchion spacing, accurate offset, and proper torque specs at all clamp interfaces. This is an advanced service part — fork disassembly and reassembly requires appropriate tools and mechanical knowledge, or should be performed by a qualified mechanic.
