PNW Components Rainier IR Dropper Post
Who's this item for: XC, Trail, and All Mountain riders that want a quality post with a short insertion depth which enables them to have a longer drop.
Actuation style: All versions of the Rainier are cable-actuated.
Spring style: The V2 posts used a coil spring while the redesigned V3 posts use an air spring which allows for the length to drop to be adjusted in 5mm increments for a maximum of 30mm travel reduction.
Infinite or finite adjustments: The Rainier is an infinite adjust post. Choose the right position for you on any part of the trail.
Internal or externally routed: This is an internally routed post so your bike will need internal dropper post routing to enable it to be installed.
Lever included: Some V2 models have the choice of having a lever included while others and all of the V3 posts do not come with a remote included.
Includes cable / housing / battery: The models that come with a remote will also come with a shifter cable included. Models with no remote supplied will not come with a shifter cable.
Saddle clamp style: Classic 2-bolt clamp allows for fine adjustment of fore/aft tilt.
- 125mm - 545g
- 150mm - 575g
- 170mm - 605g
- 200mm - 640g
Stand out features: The drop of the post can easily be adjusted in 5mm increments up to an overall reduction of 30mm. No tools required. Just follow the instructions in the images and you'll be sweet. 3-year warranty!
27.2mm V3: Due to the constraints of the small diameter of this post the 27.2 V3 still uses the same internals and coil spring as found on the V2 posts. It does not have an air spring and the length of travel is not able to be adjusted.
'Set and forget' is the Rainier's motto. With a reliable coil spring, durable seals, and a massive 3-year warranty, all you need to do is put it on your bike, and ride!
150mm and 170mm options have a larger, stiffer stanchion, and also receive an extra bushing to help fight against 'wobbly post syndrome'. They also have the option for a 1x specific, shifter style lever to be included, as well as an inner and outer cable.
The 27.2mm diameter post does not have a remote option.
- Internal routing
- Infinite adjust
- 3yr warranty

Ratings & Reviews
Good not great
by Quentin Eastop
Good for the money, but too many small gripes .. from coming off a fox transfer bought this for the extra length/ shorter insert.
Firstly, the dropper itself seems to be very sensitive to seat post clamp torque as it’s not even close to its recommended 8nm and it messes with actuating the dropper
To get the dropper moving is inconsistent and has a very on/ off feel.. almost no control over slight/ slow movements ( maybe it needs to be broken in and prob coming off a fox transfer didn’t help )
Finally too much side to side movement for my liking
Also, pnw claiming a shorter insert but they’ve just added that to the collar being super wide so although I can slam the dropper all the way into my frame now I was hoping I could get the seat a tad lower to so the wide collar just cancels that out
Hopefully it just needs to be broken in some but yeah wouldn’t have been happy paying full retail for the dropper
Top quality and reliability at a great price

Build quality and finish is top notch and the action whilst not bullet fast (and endangering your future progeny) is never in doubt. As smooth as any other top quality dropper out there even though it is spring actuated. For this price you can't go wrong. If it's good enough for Jeff Kendall Weed, it's good enough for you! 3 year warranty is awesome.

Got a few rides on it now and I have to say this seat post feels like a premium bit of kit.
Very little play at the saddle.
Seat post head is good, no creaks from the saddle.
Return speed is plenty fast.
Wiper seems to be good quality.
Really easy to install if buy a loam lever, not so easy with the included leaver.
Only downside so far, you can buy the more expensive batchelor seat post with loam lever included for less than the price of the Rainier and loam lever. That left me feeling slightly ripped off,
