His bikes are equipped with a Rigidaire pneumatic seat suspension system developed by Cox that absorbs vibrations using a small compressor and two air shocks under the seat.
Volcanic explosion earthquakes (hereafter termed EXs) are earthquakes that are observed in vulcanian and strombolian eruptions, or gas bursts, which often accompany strong air shocks or infrasonic signals.
Fluid structure interaction enhances the performance of sandwich plates relative to solid plates under intense air shocks, but not as significantly as for water blasts.
In the arena of mountain bike rear shocks, air shocks lead the way in both weight savings and user adjustment over their coil spring counterparts.
Recent results on fluid structure interaction for plates subject to high intensity air shocks are employed to assess the performance of all-metal sandwich plates compared to monolithic solid plates of the same material and mass per area.
The net result of these thermal complexities is that air shocks typically get much hotter than coil shocks and as such cannot easily be used in continual high load riding scenarios such as downhill racing and long distance downhill riding.
