The RockShox Deluxe Ultimate in 165x40mm brings the DebonAir+ air spring and refined Deluxe damper to frames specifying a compact stroke at the common 165mm eye-to-eye length. The shorter 40mm stroke suits frames with higher leverage ratios that translate the available wheel travel efficiently.

  • DebonAir+ air spring — supple initial stroke with a progressive ramp near bottom-out
  • XL4S0 4-position air volume tune for matching the spring curve to your frame
  • Reb55 rebound and Comp30 compression dials for independent adjustment
  • Lightweight Deluxe Ultimate damper body
  • 165x40mm sizing for frames with higher leverage ratios

DebonAir+ links the positive and negative air chambers to deliver a supple top-of-stroke feel that builds progressively through to bottom-out. The XL4S0 four-position tune adjusts the spring ramp-up without disassembly. Reb55 and Comp30 external dials offer independent rebound and compression adjustment from outside the shock body.

Fits frames specifying 165x40mm rear shock dimensions. Verify your frame's mount standard and hardware sizing before ordering.
