The bottom half of Cane Creek's premium 110-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 rather than the more common 1.5in or 1-1/8in. Sold as the lower assembly only.

Compatibility & fit

S.H.I.S. EC44/33: 44.00mm head tube inside diameter, 33.03mm crown race seat, 12mm stack height. The lower cup sits on top of the head tube (external cup), 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 backs every 110-Series headset bought new with a 100% lifetime guarantee, covering cups and bearings with no proof of purchase required for the claim itself. 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 for your own records.
