Misleading product description
After recently purchasing a hellbender 70 visco lower headset for my ebike, I immediately started having issues with the headset coming loose due to the dampening plates compressing, which is dangerous. As it turns out, this head set is only designed for on road use only and should not be used on any type of mountain or gravel bike. When I spoke with Cane Creek's customer service about this, their comment was the description infers this. Too bad the LBS I use who specialized in MTB didn't catch this either.
Below is a direct quote from the manufactures website. Bottom line don't waste you time or money on this product. I set $200 on fire between the product plus labor to install and remove. Cane Creeks answer....to bad so sad.
"Hellbender 70 Visco is a patented steering stabilizer headset designed to make bicycles safer and easier to control by inhibiting the high frequency steering oscillation known as speed wobble. It also makes the handling of heavily loaded bikes more stable and predictable. Stabilization is provided by a stack of damping plates built into the headset, separated by a viscous carbon gel, that helps riders maintain control, reduce fatigue and ride with confidence.
Great for e-bikes, cargo bikes, loaded touring, and commuting."
