Cane Creek's 40-Series ZeroStack top assembly delivers precision engineering with a focus on durability and minimal weight. Featuring a 44mm head tube diameter and 28.6mm stem clamp compatibility, this component integrates sealed black oxide cartridge bearings with innovative Clip-Seal technology that eliminates loose parts. The 6061-T6 aluminum construction is internally relieved for weight savings, while high-quality face-seals on crown races ensure smooth, low-friction performance. At just 44g, this tall stack (15mm) assembly offers exceptional value without compromising on the reliability Cane Creek is known for. Engineered in Fletcher, NC, it's compatible across the 10, 40, and 110-series headset lineup and supports Interlok® spacers for versatile setup options.
