There are two important parameters
in suspension systems, namely anti-squat and anti-rise.
Anti-squat is responsible for the pedaling
(accelerating) characteristics while anti-rise is for
the braking (decelerating) characteristics. These two
parameters are dependent on factors such as instant
center path, chain-line, and center of mass, which all
vary with suspension travel. As such, it is difficult to
keep anti-squat and anti-rise at a level that is
consistent throughout suspension travel.
Typical suspension bikes have anti-squat/anti-rise
levels that vary from as little as 10% to as much as
150+%. Isolink design bikes have BOTH anti-squat and
anti-rise levels that vary by less than 1% throughout
the entire suspension travel.
This gives a very consistent feeling bike regardless of
suspension position. The desirable pedaling/braking
characteristic at sag point is carried over whether the
suspension hits a bump/is bottomed out.
The graph below shows the anti-squat/anti-rise curve of
an Isolink bike. Anti-squat is set at a little over 100%
for efficient pedaling, while anti-rise is set midway at
around 44%. As observed from the graph, the
anti-squat/anti-rise values hardly vary. The dotted
lines represent other bikes, which are unable to keep
the anti-squat/anti-rise values constant.

It is possible to design an Isolink
bike with any desired anti-squat/anti-rise levels. The
first prototype Isolink bike actually had anti-squat at
around 100% while anti-rise was at 109%. Anti-rise is a
rider and riding discipline preference, the same way
some riders like the feel of floating brakes. |
