The bottom half of a Cane Creek 110-Series headset — zerostack and crown race that seats at the bottom of the head tube and carries the fork's lower bearing.

Highlights

  • S.H.I.S. code ZS56/40 — ZeroStack, 56mm cup, 40mm crown race seat
  • For a 1.5in steerer
  • Sealed cartridge bearing, black oxide
  • Black finish

What the code means

Cane Creek's S.H.I.S. (Standardized Headset Identification System) code states a headset cup's real dimensions rather than a marketing name, so two cups with the same code always fit the same head tube and steerer. The code reads as the cup type and outside diameter, then the crown race seat diameter — e.g. ZS56/40 is ZeroStack, 56mm cup, 40mm crown race seat.

Compatibility & fit

Matches a 56mm zerostack lower head tube and a 1.5in steerer only — a bottom assembly for the wrong S.H.I.S. code won't seat. Confirm your frame's lower head tube bore and steerer diameter against Cane Creek's fit chart, or ask the Tune workshop to measure and fit it.

Cane Creek backs every 110-Series headset part, including the bearings, with a 100% Lifetime Guarantee against defects — if you're not satisfied, they replace it. Everyday wear, incorrect installation and anodised-finish wear aren't covered. For warranty support, return the product to Tune Cycles and we'll manage the claim with Cane Creek's Australian distributor. This is in addition to your rights under the Australian Consumer Law — keep your proof of purchase.
