A Cane Creek 40-Series tapered headset assembly built as an OEM fitment for select Yeti frames that need a tall, wide top cover rather than the standard short cover.

Highlights

• Integrated (IS) upper and lower cups, S.H.I.S. IS41/28.6 | IS52/40
• Tapered assembly for a 1-1/8in to 1.5in steerer
• Tall, wide top cover for Yeti frames needing the oversized socket
• ZN40 sealed cartridge bearings, 6061-T6 aluminium cups
• Black finish

S.H.I.S. explained

Cane Creek's S.H.I.S. code states a headset's fit in one line: cup type (IS integrated, ZS zero-stack or EC external cup), the head tube bore it presses into, and the steerer diameter after the slash. This assembly is IS41/28.6 on top and IS52/40 on the bottom — match both halves to your frame and fork exactly.

Compatibility & fit

Listed by Dirt Works as Yeti-specific, built for 2019-onward Yeti frames (including SB130, SB150 and SB165) that take a wider top cover than the standard 40-Series short cover. Dirt Works and other distributor listings disagree on the exact cover width (51.1mm vs 51.5mm), so confirm the figure with Cane Creek or Tune's workshop against your frame before ordering — a headset for the wrong cover size won't seat.
