Best Bike Seatposts

We did a lot of research to compile the following list. This included testing all the different bikes so that we could deliver a comprehensive guide that’ll help you to make an informed decision.

Without further ado, read on for our selection of the best bike seat post on the market.

1. Cane Creek 3G Thudbuster Long Travel Seatpost

First up, you have the 3G Thudbuster Long Travel Seatpost from Cane Creek. There’s a lot to like about this bike, despite it being a bit pricey. For one thing, it offers excellent performance on different kinds of terrain and it comes with a unique shaft with two integrated parallelogram linkages.

The seat automatically shifts backward when you’re in motion and it’s designed to mimic your body’s natural movements. This feature is what makes it the best shock absorbing bike seat post on this list.

In addition to enabling you to maintain a natural posture while riding your bike, this post can play a huge role in reducing the distance from the pelvis to pedal during a shift. This makes for a smoother pedaling rhythm while allowing the bike to move effortlessly up and down whenever you’re riding on a road with lots of bumps.

The first time you use it you’ll notice a change in the bike post-suspension as though one of your tires has gone soft. But, after some time, you’ll get used to the new feel of your bike and make the most of it.

Pros
  • Versatile turnability
  • Features parallel-linkage technology
  • Comes in a variety of sizes and two colors
  • Rugged and well-made
  • Suitable for different applications
Cons
  • A bit heavy

2. Magura Vyron Seatpost with Elect

The Magura Vyron Elect Dropper Seatpost definitely deserves to be on this list as it’s one of the best bike seat posts on the market. It operates according to wireless technology which makes it ideal for anyone whose bike frame lacks an internal dropper post and anyone who needs to keep their bike packed away regularly.

Another feature of this seat post is an arrow button that’s designed to offer better shock and fork control so you can easily switch your bike’s suspension units with the electronically controlled Magura model.

There’s also a snap-on cover that comes with this seat post to avoid the ordeal of having to search for the tiny dropper button. This means you’ll be able to find the dropper button effortlessly no matter how ham-fisted you are.

If you’ve ever tried putting in and removing a routed dropper then you know how much of a life-saver this feature is. Plus, this seat post is so easy to install it’s crazy!

Pros
  • Has an offset of 0mm
  • Constructed from aluminum
  • Comes in three different length dimensions including 396mm, 421mm, and 446mm
  • Comes in a diameter of 30.9mm and 31.6mm
Cons
  • None

3. SDG Components Tellis Dropper Seatpost

Any experienced biker will tell you that the SDG brand is one of the most popular and long-standing staples in the biking world. They make some of the best bike saddles on the market, especially for mountain bikes. That’s why we had to include the SDG Components Tellis Dropper Seatpost on this list.

It comes in two different lengths – 125mm and 150mm which are available in the diameters of 30.9mm and 31.6mm respectively. This seat post has an under-bar level weight of just 36 grams and it comes with its own cables.

It also features an anodized shaft with markings that tell you how wide and long it is. Not only that but you also have a cable’s end that’s protected by durable plastic housing for protection against the elements.

You’ll be glad to know that it uses a two-bolt system to secure the saddle which the head features a 50mm depth. The base is where you’ll find the nipple to the cable, which is clamped at the lever.

Pros
  • Lightweight lever
  • Comes in different sizes
  • Solid build
  • Relevant features
  • Easy to set up
Cons
  • Allen key access isn’t that great
  • The lever is not adjustable

4. Bike Yoke Revive Dropper Seatpost

The Revive Dropper Seatpost from Bike Yoke is the best road bike seat post with dimensions of 31.6mm and 30.9mm. Yes, it has a long stroke but it makes up for this with a low-profile collar and head combo which makes it the ideal option for small frame bikes.

Another feature worth mentioning in this seat post is the fact that it doesn’t have an internal floating piston. This means that you have one less thing to worry about then it comes to this dropper.

The Allen key comes with a rotating bolt that allows you to reset the seat post’s system whenever you get an inflow of air that causes it to bounce. This feature is known as a “revive valve” and it contributes to the smoothness of this seat post.

Pros
  • Offset of 0mm
  • Constructed from aluminum
  • Has a varying length of between 397mm to 467mm
  • Versatile
  • Comes in diameters of 30.9mm and 31.6mm
Cons
  • There’s no pre-drilled hole in the remote

5. REDSHIFT ShockStop Suspension Seatpost

First of all, it’s important to address the elephant in the room and that’s the fact that this is one of the weightiest posts on this list, weighing in at 545g. However, this makes sense when you consider the fact that it’s constructed from aluminum, and this includes its internal components.

We’re definitely not mad at this design because it’s incredibly well made, sporting a length of 350mm from the base to the saddle rails, with an extra 170mm round post at your disposal between the beginning of the suspension system and the minimum insertion line. This seat post has a diameter of 27.2mm which means you’ll need a shim in order to fit a 309mm or 31.6mm seat tube.

At the bottom, you’ve got the preload adjustment plug which screws in nice and snug with a numbering system that goes from 1 to 5. Basically, you’ll experience a firmer ride the higher up you go up the score. Luckily, Redshift offers a helpful weight-based guide that makes it easier to figure out your preload setting.

According to Redshift the highest setting that you can get to without losing any function or comfortability is four. If needed, you should definitely use an innerspring which takes about 5 minutes to incorporate.

Pros
  • Offers ultra-responsive suspension thanks to optimized linkage geometry
  • Provides different rider weights thanks to adjustable springs
  • Adjustable preload stiffness
  • Active suspension travel of 35mm
Cons
  • None

6. Crankbrothers Highline 30.9 Dropper Seatpost

The Crankbrothers Highline Dropper is the best bike seat post for long-distance travel even though setting it up is no walk in the park.

The issue with installing this seatpost is the fact that it doesn’t come with the clearest instructions, plus you have to balance the tension between the inner and outer cable the whole time.

However, when you get over this initial hurdle it’s much easier to enjoy a smooth ride on your bike over long distances, thanks to this post. There’s no sag at all with this.

This seat post also comes with a salad cartridge look so that you don’t have to worry about frequent upkeep, save from the odd lubricant here and there. The best part is that this seat post is easy to mount on your saddle thanks to its low-stack height, especially after the first few times of trying it out.

Pros
  • Features internal-only routing
  • Constructed from durable aluminum
  • Unique two-bold quick-release design
  • Suitable for all types of different cockpits
  • Comes in three different sizes
Cons
  • It’s not easy to return it to its original position

7. RockShox Reverb AXS Dropper Seatpost

The RockShox Reverb AXS Dropper Seatpost is quite impressive, with features like thoughtful design, upgraded construction that includes longer friction-floating piston, and a slow-degrading new grease.

This new oil helps to maintain the seat post nice and smooth for longer while improving the overall service of the seat post. In fact, this seat post has been shown to have a generous lifespan of up to 600 hours!

This seatpost also sports a new and improved head which can now be attached onto the saddle rails using a single bolt. This technique is great for heavy-seated landings and it’s one of the features that make it truly worth the price.

  • Easy to setup
  • No difference between a cable dropper and a wireless dropper
  • 0mm offset
  • Very responsive
  • Operates really well with AXS wireless drivetrain
Cons
  • None

8. Funn Updown Dropper Seatpost

You’ll love the design of the remote lever which takes pride of place underneath the bar and is large enough to handle the Shimano shifter. There’s also a hinged clamp included with this seat post which makes the installation process that much easier (and faster!)

You’ll enjoy clean routing thanks to the four frame clips and O-rings that this seat post comes with. However, you still have to contend with the debris and dirt that the seat post is exposed to due to its rear-facing mechanism. Still, it’s the best carbon seatpost we’ve seen in a while.

Pros
  • Easy to install
  • Comes with a reliable and ergonomic lever
  • Offers great value for money
  • Features internal cable routing
  • It’s a big upgrade from this brand’s previous dropper post models

How to Find the Best Bike Seat Post

There are more than just a few considerations that you must consider when looking for a new seat post and we’ve put together a list of the most important.

While seat posts have pretty much the same function, they come in all types of different sizes with varying features.

However, most people don’t notice all these differences because the seatpost is not the most noticeable part of the 10-speed bike.

Material

The material that your seat post is made from is incredibly important. The most popular materials include alloy, carbon, and titanium.

Alloy posts are known for being cheaper, lightweight, easy to maintain, and install. But the downside is that they’re also rough around the edges and will make your ride that much more difficult.

On the other hand, you have pricier titanium posts which offer a softer ride and are lightweight as well. Carbon posts are also soft and lightweight but they’re often difficult to install and cost more than the previous two options.

However, the most important thing to keep in mind when considering the materials that your bike seatpost is made from is to utilize the right amount of grease when connecting it to the frame to avoid unnecessary damage and seizing.

Layback

Layback refers to the distance between the middle of the saddle rail cradle and the middle of the post. It has a marked effect on the comfort and reach of your seat post.

A post that has a considerable amount of layback typically puts you in a stretched-out position.

If your bike saddle doesn’t feel efficient enough for your needs or you just want efficient time trialing then you should definitely consider a layback-free inline post.

The one downside of this is that inline posts can make for a harsher and less comfortable ride due to reduced flexibility.

Saddle Attachment

At the topmost part of the seat post is a clamp or cradle where the saddle rails stay and it should be flexible enough to allow for back and forth movement. That way, you can enjoy a more comfortable and stable saddle position.

You’d ordinarily use one or two bolts to keep the saddle clamp in place, while a dual-bolt system is the most common because it’s able to keep the load in place. You also have fore and aft bolts while others are based on a left and right orientation depending on the specific manufacturer.

Some systems feature a sideward bolt system so they are able to keep the saddle rails in place while remaining flexible.

Length

It’s equally important to ensure that your seatpost has the right length for your needs.

Seat posts come in lengths of 280mm to 400mm and the one you pick will depend on the amount of post that’s left showing on the rear when you get on the bicycle. If you’re unsure then you should measure your old post and use that as a reference.

Regardless of the seat post length, you should definitely avoid going over the minimum insertion limit. If your current post doesn’t meet this requirement then you might need to go a size up just to be on the safe side.

Diameter

Next you have the seat post diameter. This is another essential feature to consider. Most seat posts have a diameter of 27.2mm, 30.9mm, and 31.6mm. Older frames often feature a thin 26.8mm diameter but you won’t find a lot of them on the market nowadays.

A wide diameter often translates to a stiffer ride but most frames have a post that measures 31.6mm, while 27.2mm is a popular choice for the comfort factor.

It’s worth noting that some frames have a diameter of 27.2 mm for racing purposes which leads to a softer feel, especially on the back end.

Color

Color is another crucial aspect that plays a role in selecting a bicycle seat post.

Ideally, your post should match the stem and bars, but you could always opt for something unique such as a Union Jack flag which is what’s featured on the design of the Thomson Elite Union Jack seat post.

Conclusion

Well, there you go! So far in this article, we’ve provided you with all the helpful tips required to help you figure out how to find a quality seat post for your bicycle.

In addition to comprehensive reviews of the top models on the market, we also gave you an updated list of features and functions to prioritize in order to narrow down your options.
