The 40-Series is the workhorse of Cane Creek's headset line-up and incorporates all the features necessary for a durable, lightweight, and long-lasting headset while offering the perfect balance of performance, durability, and value. 

Contoured and relieved 6061-T6 aluminum for minimized weight and maximized strength with split-lip sealed stainless-steel bearings. The low friction, dual-seal crown race, and top cover provide maximum sealing from contaminants, plus a captured compression ring design for carbon steerer compatibility (Interlok spacer compatible, sold separately).
