Cane Creek 40-Series Headset – Tapered Steerer

Features

• ZN40 bearings are corrosion-resistant zinc-coated, machined-steel cartridge bearings with hardened steel balls, which vastly increases the longevity of the 40-series headset
• 6061 T-6 aluminum cups and covers are internally relieved to reduce weight
• Durable steel crown race
• Interlok® spacer compatible (spacers not included)
• Innovative Clip-Seal completely seals the top assembly and captures the compression ring to reduce the number of loose parts
• High-quality, low friction face seals on the crown races
• Designed for 1-1/8 to 1-1/2 in. tapered steerer tubes, or straight 1-1/8 in. steerers with a conversion crown race (not included)
• External cups press into head tube
• Integrated bearings fit directly into compatible head tubes without the need of a bearing press
• Zero stack uppers press into head tube with very little stack height
