The 7700 Thru-Rod shock is the latest development in short track shock technology. The thru-rod design eliminates the gas pressure feel entirely. Thru-Rod design eliminates any displaced fluid, so the need for a separate head valve or nitrogen chamber is no longer needed. This drastically reduces running friction and improves consistency by eliminating the effect of rising gas pressure commonly associated with gas shocks. Also by eliminating the head valve, this reduces the amount of pieces and flow paths the fluid must take. This allows the shock to change direction quicker, resulting in more mechanical grip.
