The bottom half of a Cane Creek 40-Series headset, built as an external-cup conversion: S.H.I.S. EC44/33, for a 44mm lower head tube running a 1-1/4in steerer. Sold as the lower assembly only.

Compatibility & fit

S.H.I.S. EC44/33: 44.00mm head tube inside diameter, 33mm crown race seat, 12mm stack height. The lower cup sits on top of the head tube, so check your frame has at least 12mm of clearance above the head tube for the cup to seat correctly. Internal parts are cross-compatible across Cane Creek's 10, 40 and 110-Series headsets, but the cup and crown race must match this exact S.H.I.S. code. The Tune workshop can confirm your frame's standard and fit it.

Cane Creek's 40-Series (Forty) headsets carry a 1-year warranty to the original owner 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.
