ViscoSet offers viscous damping to make bicycles safer by inhibiting the uncontrolled steering oscillation known as speed wobble. Speed wobbles are vibrations that start small and get worse due to harmonics. This frightening shimmy can affect the handling of any bicycle under certain conditions and is the result of many different factors.
$0.90 – $80.00
Utilizing specially designed damping plates above the bearing in the upper assembly, ViscoSet stops the oscillation known as “speed wobble” before it can grow to a dangerous level.
The Viscoset’s ability to reduced arm fatigue, provide a more stable ride, and standup to the elements lends itself to a variety of applications including Bikepacking, gravel and ultra-endurance.
Micro-thin plates are inter-leaved in an encapsulated cartridge and connected to both the frame and the steerer tube. As they rotate against each other, a fluorocarbon gel between each layer provides viscous damping and stops the oscillation of the handlebars before it grows to a dangerous level.
By changing the orientation of the Viscoset shims, riders are able to personalize the damping characteristics to their preferred amount of damping.
“I’m sold on the ViscoSet. I wish all my bikes had one installed. Reduced arm fatigue, a more stable ride, and more steadiness when packing and unpacking the bike are all great benefits. However, I also really appreciate the feel of it. With the added resistance, it simply has a high quality feel.”
In 1992, we brought the Aheadset®, the original threadless headset, to market – kicking off a major change in the way bicycle frames and forks would be developed going forward.
The original design of that revolutionary headset is still found in almost all bikes on the market today.
