How it Works

This remarkable seat post
uses
a gas spring and a soft
coil spring that work together
to suspend the rider. The gas spring supports the rider while the coil spring provides progressive compression. Because the gas spring carries most of the load the coil spring can be much softer (35 lbs/in. instead of 100-160 lbs/in.) This combination of gas/coil spring produce a superbly soft suspension not available until now. So unique is the concept it won a U.S. patent .

Features/Benefits

Nitrogen Gas Suspension Benefits

HIGH SHOCK ABSORPTION! Gas/Coil spring designis extremely responsive. A gas spring and soft coil spring work together to absorb most of the impact, therefore less of the impact is transferred to the rider.

REDUCED VIBRATION TRANSFER Gas charged springs with internal oil dampening neutralize vibrations. As the gas spring compresses and then smoothly rebounds, the rider is isolated from almost all vibration. V ibration is dramatically reduced. Expect to rideyour favorite trails for much longer without fatigue or soreness.

NitroPro has a UV
resistant vinyl boot.
Ride through the
elements at ease!

Nitrogen Gas Springs with oil are permanently sealed which means ZERO maintenance.
Expanding Key Design removes any side to side play by growing in width inside the steel stanchion as an adjustment nut is turned. Nothing ever to rebuild, just turn the adjustment!
Pre-Load adjustment fine tunes the gas/coil spring to your specific body weight. Use any flat blade screwdriver. No hex wrench needed.
NitroPro's exclusiveSlotted Ground Stanchion creates a 'Zero Stiction Area' where normally loads would behighest on other stanchions. The Expanding Key passes through slot to stop rotation of stanchion. No key ways to wear or keys to replace ever! Special Teflon bearings are designed to transfer a micro layer of Teflon onto the ground surface of the stanchion creating a Teflon to Teflon interface for stictionless movement for the full travel.
