S.H.I.S. explained

Cane Creek's S.H.I.S. code states a headset's fit in one line: cup type, head tube bore, and steerer diameter after the slash. The /40 on this bottom cup means it takes the 1.5in tapered crown, not the /30 straight version.

Compatibility & fit

Fits a 44mm head tube with an external-cup bottom, tapered 1-1/8in to 1.5in steerer. Cane Creek notes the EC44 conversion lower cup needs at least 12mm of insert depth inside the lower head tube — check this before fitting to an unusual frame.

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.
