S.H.I.S. explained

Cane Creek's S.H.I.S. code states a headset's fit in one line: cup type (ZS zero-stack, EC external cup or IS integrated), the head tube bore it fits, and the steerer diameter after the slash. The /30 on this bottom cup means it takes a straight 1-1/8in steerer, not the /40 tapered version.

Compatibility & fit

Fits a 44mm head tube top and bottom, straight 1-1/8in steerer only. Dirt Works' own running text for this part labels it a 'Tapered Assembly', which contradicts both the product name and the EC44/30 code — EC44/30 is Cane Creek's own straight-steerer crown race fitment. This listing follows the code and name: straight steerer, not tapered.

Cane Creek covers 40-Series headsets with a 1 year warranty against defects in materials and workmanship. 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, so keep your proof of purchase.
