The Hellbender 70 Slam is Cane Creek's ultra-low-stack headset, built for riders who want to run their stem as close to the frame as possible — a slammed, aggressive position, or a short-steerer fork with no room for a standard headset.

Highlights

  • Ultra-low stack top cover: 2mm, versus roughly 8mm on the standard Hellbender 70 ZeroStack upper
  • S.H.I.S. ZS44/28.6 upper cup
  • Sealed stainless steel Hellbender bearing
  • Sold as the upper assembly only — pair with a matching lower cup or keep your existing lower
  • Backed by Cane Creek's Hellbender 70 headset warranty

Compatibility & fit

Upper cup: ZS44/28.6, a ZeroStack (recessed) bearing with a 28.6mm (1-1/8in) stem clamp, in Slam's 2mm-stack cover. This is the upper assembly only; it doesn't include a lower cup. Confirm your frame's S.H.I.S. and fork steerer length before ordering — a slam headset needs enough steerer to still thread the stem bolts safely. The Tune Cycles workshop can confirm your setup and fit it.

Cane Creek's published warranty page lists a 2-year term for Hellbender 70 headsets; it does not itemise the Lite or Slam versions separately, so this is the family term, applied here For warranty support, return the product to Tune Cycles and we'll manage the claim with Cane Creek's Australian distributor. This is in addition to your rights under the Australian Consumer Law, so keep your proof of purchase.
