SUSPENSION TECHNOLOGY
SUSPENSION THEORY
When discussing how Naild’s R3ACT - 2 Play suspension
system works, one needs to look through a different lens
to understand the technology. R3ACT – 2 Play cannot be
discussed using our normal suspension vocabulary, as it
utilizes an advanced understanding of physics to isolate
the rider’s mass from collapsing the rear suspension upon
acceleration, allowing for a reduction in damping that gives
riders a level of suspension performance that has never
been achieved until now.

LESS DAMPING = LESS RESISTANCE = LESS FRICTION

the Naild system is
counter balanced by

THE RESULT IS ZERO TRADEOFF BETWEEN BUMP ABSORPTION AND PEDALING EFFICIENCY.
THE RESULT IS A TRADEOFF BETWEEN BUMP ABSORPTION AND PEDALING EFFICIENCY.
The Naild R3ACT 2 - Play suspension system has a 60%
overall reduction in damping (restriction) creating a bike
that has both pedaling efficiency and bump absorption, with
zero sacrifice. This is made possible by a feature Naild dubs
equilibro.
All current suspension systems balance pedaling & bump
forces with compression damping, or simply restriction. This
results in compression damping (restriction) in the shock to
control the pedaling forces while riding. So, there is always
a compromise between bump absorption and pedaling
efficiency.
