S.H.I.S. explained

Cane Creek's S.H.I.S. code states a headset's fit in one line: cup type, the head tube bore it presses into, and the steerer diameter after the slash. IS42/28.6 on top takes a 1-1/8in steerer; IS52/40 on the bottom takes the 1.5in tapered crown.

Compatibility & fit

Fits frames with a 42mm integrated top bore and a 52mm integrated bottom bore, tapered 1-1/8in to 1.5in steerer. If your frame or fork differs from this exact pairing it won't seat — check your frame's own headset code before ordering, or ask Tune's workshop to measure it.

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.
