Bachelor IR Dropper Seatpost

Whether your ride consists of a lung-busting climb leading to an epic descent, or endless stretches of undulating singletrack, being able to adjust your saddle height on the fly is key to becoming a faster rider. PNW Components understands that you need a lightweight and reliable dropper post to tackle this type of trail riding, and created the Bachelor IR Dropper Seatpost so you can climb easier and descend faster.

The Bachelor is all new and shiny for 2019. PNW upgraded the already loved post with a larger diameter stanchion for increased post stiffness and a lighter overall weight. The New Bachelor also gets an added DU bushing for enhanced wobble resistance, eliminating tedious side to side play at the saddle.

Some of you may wonder how the Bachelor differs from PNW Components' other internally routed dropper post, the Rainier. Well, the Bachelor uses a replaceable sealed air cartridge as opposed to a coil spring, and is also made out of a lighter 7075 alloy.

  • PNW's leading dropper is even lighter and more reliable
  • Larger diameter stanchion increases the post's stiffness
  • Added DU bushing for improved wobble resistance
  • Sealed damping cartridge offers consistent performance
  • Adjustable air pressure to customize the return speed
  • Infinite Adjust lets you set your saddle height anywhere
  • Backed by an impressive 3 year warranty
  • Item #PNW000T

Purchased this a while back. Probably a good year or so. Been solid with no issues whatsoever. Just wished i got the 150 length but wasn’t available at the time. Still happy with them that i got one for my Hardtail and both had never any issues. Solid.

Great dropper. Long insertion length.

I've put it through the wringer

Great dropper, works awesome, good speed. The insertion length for the 170 ended up being way longer then I expected wasn't even close to fitting the bike I had expected it would. My fault for not double checking measurements but just a heads up the 170 is really long.

I've used it several times

I love this dropper post. The bachelor post is a top contender for internally routed posts. It's super smooth and the size I got, I was able to adjust the air pressure. Install was simple and Im using the PNW loam lever. HOWEVER -- be aware -- if you purchase this product here on backcountry, it will NOT come with a dropper post cable or cable housing. The bike I installed this on did not come with a dropper so I did not already have the cable or housing. Just want to make sure that was known. I am attaching a video to PNW Dropper Post install. It's super simple and love the warranty that comes with it. I got the 31.6 at 200mm travel and the seat post is firm without any sway side to side. Love it!

Great and Reliable Post!

I've put it through the wringer

The Bachelor is a pretty awesome! It has very little side-to-side play in it, and has adjustments for seat return speed. I also like the fact that you can rebuild and service the post yourself when the time comes. One small annoyance is that you need to remove the seat to access the air valve for adjusting the return rate.

Awesome post

I've used it several times

People often say, 'This is a great post for the price,' but I would definitely leave off the 'for the price' part. It's a very reasonably priced piece of equipment, but the performance gives exactly zero indication of where it sits in the pricing hierarchy. It's fast, smooth, and has that nice little 'thunk' at the top-out point to tell you it's time to let go of the lever. I forget about it because it's so good at its job, and that's all I can ask from any component.

Love my PNW dropper

I've put it through the wringer

I ride 2 to 3 times a week 10 to 15 miles on rough techy trails, the dropper is up and down a lot, after a couple hundred miles it is broke in and still works great! PNW also has great customer service, I have contacted them a few times with questions and they always get back to me within one day.

Easy to install and great function

I've used it several times

My gearhead Jacob was awesome with helping me make sure this fit my bike and answering questions I had about included hardware. I was very pleased with how easy this dropper was to install, I had it all hooked up and ready to go in 20 mins. I have put almost 100 miles of use on it so far with zero issues. The action is super smooth, even with it getting caked in mud during this wet spring. I am running this on a second generation Surly Karate Monkey.


cool healer, best trail dogs ever!!


Does this product come with proper cable and cable housing to install the dropper?

going to answer my own question... NO, this does not include any cables or cable housing. ONLY the dropper post. You will need to purchase a dropper post cable kit to install this dropper if you do not currently own the cables necessary.


Does this come with a lever or is that sold separately?

The lever is sold separately and PNW have a couple different options. Take a look at item: PNW000Q
