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.

GEAR REVIEW.COM
...The damping mechanism built into the gas spring of the NitroPro is about perfect.
I never felt that the post was trying to eject me from the saddle. It always returned to the top of its stroke smoothly in a controlled manner.
...The NitroPro seat post has about a smooth an action as I have ever felt in a seat post, and the expanding key keeps the post moving up and down, not rotating side to side....Summary... put it plainly, it works well. ...the rider is rewarded with a noticeably smoother ride.
I heartily recommend it to anyone still riding a hard tail mountain bike. James Sharp is a contributing editor for GearReview.com specializing in mountain biking.

NitroPro offers a solution by coupling a coil spring with pressurized nitrogen gas.
On the trail, the NitroPro is definitely plush and takes big hits with ease.
Compared to other suspension posts I've ridden, the NitroPro feels the most full-suspension-like... Overall, the NitroPro is on the right track with using pressurized nitrogen.
Coil springs and elastomers can be geared toward either big hits or small vibrations; the NitroPro excels at both...All suspension posts have positive and negative aspects -- the NitroPro just has a few more strengths and a few less weaknesses. by Dain Zaffke
MOUNTAIN BIKE ACTION
"The NitroPro moves into action and smoothly (ever so smoothly) compresses and rebounds back to its fully extended position.
We wish more forks had action as smooth as the NitroPro.
This is a big step forward in suspension seatpost performance."
"If you currently employ a suspension seatpost, the NitroPro would be a serious upgrade.
You won't believe the adjustability, amount of travel and quality of travel."
You will feel less shock compared to full suspension bikes* and other suspension seat posts that use a stiff coil air or elastomer spring.
There is less shock because a gas spring allows a softer more active coil spring to absorb the shock instead of passing it to the rider.
Elastomers, Air, Pivot type suspension seat posts with high spring rates (100-160 lbs/inch) just don't have the shock absorption ability to give you comfort and satisfaction.
*compared to the first two inches of travel of a full suspension bicycle. 90% of suspension travel is in the first two inches.

I am not sure what size seat post diameter I need?
1. Remove your current seat post from your bike and look at the lower part of the seat post below the "Min.Insert" line.
2. You will see a number like 26.8 or 27.2 or 30.0 etc. This is the size you will need when ordering.
3. If not clearly marked take post to a local bike shop and have them measure it or you can measure the diameter yourself if you have calipers. Another way is to go to the frame manufacturers website.
NitroPro needs a minimum of 4.5 inches (114mm) of space.

How It Works
|
This remarkable seat
post
uses a proven method of shock
absorption. A charged nitrogen
gas chamber completely isolates
the rider from all vibration and
movement of the lower post.
A gas and coil spring work to-
gether to suspend the rider. The
gas 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. Similar to
auto suspension using gas shocks.
So unique is the concept it won a
U.S. patent. |

Gas Suspension Benefits
100% SHOCK
ABSORPTION! Gas/Coil spring design
is extremely responsive. A gas
spring and soft coil spring
work together to absorb 100% of
the impact, less
of the impact is transferred to
the rider compared to
seat posts that use stiff
elastomers/coil springs.
Overall you will experience
improved performance
levels over a wider variety of
trail and road conditions.
REDUCED
VIBRATION TRANSFER As bike rolls
over obstacles vibration is
transferred to the frame
causing the rider to become
fatigued. 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. Compared to non
gas suspension seat-
posts vibration is dramatically
reduced. Expect to ride
your favorite trails for much
longer without fatigue or
soreness. |
NitroPro has a
double tied UV resistant vinyl boot. Ride through the elements at ease!
