Setting Top Load Spring Force
1. Determine initial spring setting from spring
force chart below.
2. Compress the spring with the locking ring just
enough to allow the adjustment ring into its
correct setting.
3. Move the adjustment ring to the desired
setting. Bring the locking ring down and jam
the rings together with a spanner wrench.
4. For optimum results check download force
with a force scale.
5. Set headset on the scale and manually
compress the spring downward 5mm. Take
the force reading at this position. The lines on
the spring cover are .100” (2.5mm) apart, so
two lines equal the recommended .200” (5mm)
compression.

NOTE: The charts above provide actual spring
loads without any added load due to the
weight of the headset. These spring loads are
valid for any headset. Not all headsets have
the full range of settings; some headsets do
not have a ‘3.0’ setting, other headsets do not
have ‘1.0’ or ‘1.5’ settings. The spring loads
are calculated at the given deflection as listed
in the chart.
