What is a Suspension Linkage?
The rocker arms and rods connecting the swingarm to the rear shock, tuning how the suspension feels.
Simplified animation — not to scale.
In plain English
On many bikes the rear shock doesn't connect directly to the swingarm — instead a series of pivoting links translate the swingarm's movement, often making the suspension progressively firmer the further it compresses.
“A mechanical gearbox for suspension travel — changing the leverage between wheel movement and shock movement as the wheel travels further.”
How it works
As the rear wheel moves up over a bump, the linkage rotates through its geometry, changing the mechanical advantage between wheel travel and shock compression. This 'rising rate' effect gives a soft, comfortable initial stroke that firms up progressively to resist bottoming out on bigger hits.
Signs of trouble
- ⚠Clunking or knocking from underneath the bike
- ⚠Play felt when pushing down on the rear seat
- ⚠Rear suspension feeling harsh or inconsistent
- ⚠Grease visibly missing or contaminated at the pivot points
