The Cane Creek Hellbender 70 headset is engineered to bridge the gap between the 40-series and the premium 110-series. It incorporates the same core design philosophy, sealing architecture, and stainless-steel Hellbender bearings found in the 110-series, while remaining closer in price to the 40-series.
With a clean, modern aesthetic and a strong focus on durability, Hellbender 70 is designed for riders who demand long-term reliability, smooth performance, and excellent value—making it an ideal choice for modern road, gravel, and mountain bike builds.
HIGHLIGHTS

Precision · Quality · Value
Machined from 6061 T-6 aluminum and finished with a bright-dip anodized black coating, the Hellbender 70 delivers an excellent balance of strength, weight, and durability. Its low-friction upper bearing seal combined with a double-lip lower bearing seal provides comprehensive protection against water, grit, and debris—bringing premium-level durability previously reserved for the 110-series to a more affordable headset.
At its core, the Hellbender 70 features Cane Creek’s stainless-steel Hellbender bearings, purpose-built and extensively tested for heavy-duty use and extreme riding conditions.
Hellbender Bearings
Hellbender bearings are designed to survive the harshest environments, keeping your steering smooth and consistent through rain, mud, dust, and grit.
Sealed stainless-steel bearing construction
Advanced sealing elements
Designed for long service life in demanding conditions
Interlok® Spacer Compatibility
The Hellbender 70 is compatible with Cane Creek’s patented Interlok® spacer system.
Interlok spacers mechanically nest into each other and into the top cover, creating a solid interface that minimizes movement under load and distributes headset preload evenly.
Compared to traditional alloy spacers, Interlok spacers are approximately 25% lighter.
Spacers sold separately.
Cane Creek Headsets – A Legacy of Innovation
In 1992, Cane Creek introduced the Aheadset®, the world’s first threadless headset, fundamentally changing bicycle frame and fork design. That original concept remains the foundation of nearly every modern bicycle today.
The Hellbender 70 continues this legacy by combining proven engineering principles with modern materials, sealing technology, and refined aesthetics.
