Cane Creek Hellbender 70 headset is designed to bridge the gap between the 50-series and 110-series headsets. Hellbender 70 has all the design characteristics, sealing elements, and stainless steel Hellbender bearings found on a premium 110-series headset, at a price closer to a 50-series. With a cleaner aesthetic, Hellbender 70 offers a very high level of durability with a look to complement modern builds. Cups and covers are internally contoured and relieved to minimize weight and maximize strength. Top cover with low-friction upper bearing seal completely seals cup from contaminants and is fully captured by the top cover with no loose parts. Alloy Dual-Seal crown race provides excellent seal efficiency with low friction. Premium, sealed stainless-steel Hellbender 36x45 degree angled contact bearings. Carbon friendly captured compression ring. Rugged Bright-Dip anodized finish. Interlok spacer compatible (Sold Separately).
