Dropper Posts For Fat Bikes

The one fat bike part that will change your riding

The dropper post, what negative thing can I say about the dropper post. Nothing. Well maybe specific things about specific ones, but as a whole, the dropper post is a beautifully thought of must have fat bike… any mountain bike part.

If you do not know what a dropper post is, picture a seatpost that can get out of your way when you need it to. When do you need a seatpost out of your way? Descending downhills, drops, roll ins and it’s nice to get it out of the way in technical sections like rock gardens. So with a dropper post you can get the seat post and saddle out of your way for those listed conditions, then pop the seat back up so you can get your full leg extension again.

I have installed dropper post on my singlespeed Surly Pugsley and my singlespeed Surly Wednesday. The dropper post has really changed my fat bike riding by giving me a lot more confidence. So crack open a beer and let’s talk about this wonderful device called a dropper post.

External Dropper Post

Most fat bikes today have internally routed cables, but fat bikes like the Surly Pugsley and older Specialized FatBoys run all their cables externally. Dropper posts are fairly new to the market (unless you are talking to some real old school mountain bikers) so most of them are internally routed, but fear not there are external dropper post that will work with your fat bike.

DNM Dropper Post

From my experience the DNM dropper post is the first dropper post that most people have purchased. I have seen this on a number of first generation Specialized FatBoy, Trek Farley and the Surly Ice Cream Truck fat bikes.

On the MTBR.com forums the DNM dropper post gets 3.5 stars out 5. I did not read all the reviews, but overall people were happy. The 1 star reviews are always funny, people expect a $1000 performance out of a $150 dropper post, some people complain just to complain. Anyways you can get the DNM dropper post here.

KS (Kind Shock) eTen

This is the dropper seatpost that I currently have installed on my Surly Pugsley. I am a bit nostalgic for this dropper post as it is the first one I got and it completely changed my riding. After installing this post I was confidently attacking downhills, doing three foot drops and launching off of some jumps on my fatty.

The price on the KS eTen fluctuates in price but at around $150 it is hard to dispute the value. Are there better ones on the market, of course; but if you are on a budget you would be hard pressed to complain about it. You can purchase the KS eTen dropper post here.

PNW Components Cascade Dropper Post

The PNW Cascade dropper post is the most expensive external dropper post on our list. I would really go with one of the other two unless the fat bike you are installing this on is going to be your one and only fat bike for years to come.

Aside from being the most expensive external dropper post on the list, the PNW Cascade dropper post is also the highest rated. Hmm, for about $75 more then the other two dropper post, the higher review could be worth it. You can get the PNW Cascade dropper post here.

I have loved my KS eTen dropper post on my singlespeed Surly Pugsley, but I have to admit, I’m a bigger fan of my singlespeed Surly Wednesday that has an internally routed dropper post.

Internal Dropper Post

If you have a more modern fat bike or higher end fat bike you most likely have internally routed cables. Also if you have a high end fat bike it might have come with a dropper post already, if it came with a RockShox Reverb I feel your pain. Working in a bike shop I’ve seen a number of RockShox Reverb issues so much so when a customer says I’m having a problem with my dropper post I assume it’s the RockShox Reverb. Well if you are looking for a RockShox Reverb replacement or just want to get an internally routed dropper post here are a few recommendations for you.

KS eTen Integra Dropper Seatpost

If you are on a budget and you have and internally routed fat bike, this is the dropper post for you. I would have listed the KS Crux-i that I have installed on my Surly Wednesday, but the $150 price tag for an internally routed dropper post almost seems too good to be true.

The only limitation I see is that the KS eTen integra is only available in a 31.6 diameter. This limits the amount of fat bikes that can use this KS dropper post, but it’ll be great if you have a Trek Farley! You can get the KS eTen integra here.

Crank Brothers Highline Dropper Seatpost

Ok, cool, the Crank Brothers Highline is supposed to have the best dropper post remote in the game. Also you can get the Crank Brother Highline in various travel lengths including: 100mm, 125mm and 160mm! I personally find 125mm to be enough. But imagine the gnar you could handle with a 160mm dropper post!

Since the Crank Brothers Highline dropper post comes through in a diameter of 30.9 and 31.6 it will fit most fat bikes on the market. Crank Brothers is known for their high quality bike components, so I would say you can’t go wrong. To get the Crank Brothers Highline dropper post go here.

PNW Components Bachelor Dropper Seat Post

I was about 10 seconds away from pulling the PNW Bachelor from the list, but then I saw it comes in two serious travel lengths: 150mm and 170mm! Highland here I come! Pink Bike could not even say anything negative, “What’s lacking about the Bachelor 150? A big name and marketing budget. That’s it.”

Oh, the PNW Bachelor comes through in the diameters of 30.9 and 31.6. It is going for just north of $300, but 170mm of travel… mmm travel. Anyways, you can get the PNW Bachelor dropper post here.

RaceFace Aeffect Dropper Seatpost

What can I say, it’s RaceFace. If you have been fat biking or mountain biking within the past decade you have most likely heard of this mountain bike parts company. RaceFace makes high performance mountain products for a reasonable cost.

The RaceFace Aeffect dropper post comes through in 30.9 and 31.6 diameter, so it will fit most fat bikes on the market. The RaceFace Aeffect dropper post also comes through in two different travel lengths: 125mm and 150mm. If it’s RaceFace you really can’t go wrong. You can get the RaceFace Aeffect dropper post by going here.
On my singlespeed Surly Wednesday I have the KS Crux-i. I personally have not had any issues, but the one customer issue I personally came across KS happily took care of it as a warranty issue.

Dropper Post Remotes

If your got yourself a KS dropper post it most likely came with a dropper remote that sits on top of your handlebars on the left side. Yeah, it works, but do yourself a favor if you are running a 1x system on your fat bike, get a dropper post remote that positions below the handlebar; like where a front draillier shifter lever used to be.

KS Southpaw Left Handed Remote Lever

If you got yourself a KS dropper post the KS Southpaw dropper post remote is a must have. KS typically comes with a dropper post remote that sits on top of your handlebars. This is fine and dandy if you are style running a front derailleur on your fat bike, but most of today’s fat bikes are coming through with a 1 by whatever drive train. What most fat bikers are now doing is placing their dropper post remote where the front derailleur shifter used to be. It makes it a lot easier and convenient.
