Redshift ShockStop

Features
  • Load capacity: 242lbs
  • Size: 16.61 x 3.5 x 2.64
  • Travel suspension: 35mm
  • Weight: 1.54lbs
  • Material: Stainless Steel

Other features: fit all bikes, easy to install, dampen bumps and vibration by up to 60%, swappable springs.

The Redshift ShockStop offers a relatively simple design. It consists of two 6061 aluminum sections with extensions that pivots on the two bearings attached to the steerer clamp. It has a standard 31.8mm handlebar diameter compatibility and 20MM of damped suspension travel. It has two elastomers within the stem cavity with a preload wedge which can be swapped out for extra support and comfort depending on the rider’s weight and preference. This suspension seat post ranges from 90-120mm with a +/- degree rise. The ShockStop stems fit standard 1-⅛” steerer tubes and are also available for oversized  1¼ bikes. It offers up to 70% bump and vibration dampening, helping to relieve pain associated with long rides, which helps reduce fatigue and increases efficiency. This shock absorber seat post offers comfort as well stability for the most relaxing ride you can get.

When we tried out the suspension support seat, we weren’t sure how it would feel, but we were pleasantly surprised. The handlebars moved up and down well with the bumps and even over gravel roads. We tried it out on some rough terrain, too, and it handled great. The rebound rate and compression can occasionally become a little rough if the rebound doesn’t respond quickly enough. This rarely happened and only ha[pened on repeated bumps. As expected, the performance varied slightly depending on your body position. When doing downhill, you notice that the anding improves. There were no bottom-outs when we took it out on rougher terrain, so they give more than enough. Although on some of the larger bumps, some of us hit the rebound top-out limit. This is one of the best seat posts for heavy riders and one of the lightest on our lists. If you often go mountain biking, this is also one of the best seat posts for that.

What do we love it for?

  • Redshift SockStock has many sizes available from 90 to 120mm, plus its lightweight. It’s very affordable and fits most bikes. The elastomer well controls the suspension, and this allows you to choose the amount of firmness you want. We noticed that when we used this suspension seat post, we could go farther and weren’t as tired when we were done riding.

What were we disappointed with?

  • The stem is chunky due to its angular design and has large bolts, but it doesn’t take away from its excellent overall design. Changing the saddle height and handlebar distance wasn’t as easy as we would like. Finding just the right fit was difficult, and it would take a few adjustments until getting just the right feel.

Premium Pick

Kinekt 2.1 XL2

Features
  • Load capacity: 320lbs
  • Size: 19.2 x 4 x 2.3 inch
  • Travel suspension: 35mm
  • Weight: 1.75 lbs.
  • Material: aluminum

Other features: hardware is made of stainless steel, comes in 4 spring sizes, 1-year warranty.

The Kinekt 2.1 XL2 is an aluminum seat post that provides maximum comfort at a minimum price. It comes in four different spring sizes from 100-320lbs. This makes choosing what works for you simply and quick. It has interchangeable springs, an adjustable preload bolt, is available in different diameters: 25.4mm, 27.2 mm, 30.9mm, and 31.6mm. It has a setback of 12mm, 25mm, a distance of 0-35mm, and is made from 6061 AL. Riders can easily change the size of the springs by turning the knob to the appropriate weight range. Because of this unique feature, riders are offered more comfortably and can find just the right tension level suited for them. This version of the Kinekt was explicitly designed for heavier riders who love to ride but have trouble finding the correct suspension seat post for their weight. It’s compatible with most bikes and simple to put on your bike.

The main reason we chose the Kinekt 2.1 XL2 over the Kinekt 2.1 is the heavier springs. This is the reason we believe this suspension seat post is the best for heavier riders. The seat post isolates your body from the large jarring bumps so that you don’t get as sore or tired trying to keep your bike under control. We found that we could ride for longer distances because we didn’t have to fight the bike so much, plus we had much more control. Even when we went down rough terrain, we stayed comfortable. The best part was with the two springs; you don’t move side to side even when riding gravel roads. We decided to try it out on a few different types of bikes during our review and found this one to be the best suspension seat post for road bikes.

Why did it make our list?

  • if you like riding in the woods, you seldom bounce off the ground, even in the rear tire. The seat is exceptionally comfortable, which makes it great for long distances. You can expect a smooth ride even if you’re riding at high speed.

What is not ideal about it?

  • It tends to be bouncy, especially when you ride over big bumps. Because of the bounce, it’s difficult to maintain a steady pace, but if you tighten the springs, it does help improve it. If you use the 0 settings, it bottoms out, so you may want to consider a higher spring option.

Best Versatility

Cane Creek Thunderbuster ST

Features
  • Load Capacity: 330 lbs
  • Size: 19 x 5 x 4
  • Travel Suspension: 50mm
  • Weight: 1.28 lbs.
  • Material: nylon

Other Features: easy to install

This is the latest generation of suspension seat posts by Cane Creek. It has a seat post diameter of 27.2, travel of 50mm, and a minimum extension of 100mm with a maximum extension of 244mm. With the max rider weight of 330 lbs. It’s a medium-firm elastomer pre-installed from the factory. It comes with soft and firm elastomers that you can change out if you want. The post itself is made from forged aluminum. The seat clamp is a single bolt fastening with an angle-adjustment design. The seat is designed to support both round and oval rails that keep it in alight with the rear wheel. It makes the Thudbuster move up and down, helping the seat absorb the force at the same rate.

Thudbuster works well on rough asphalt and concrete by making all-terrain feel smoother, making for a more comfortable ride. It offers similar linkage technology with a redesigned seat post for increased durability. The shock absorber seat post works great with eBikes. A few of the upgrades the Thudbuster ST has that the previous version didn’t is designed with road bikes in mind and those who make long commutes. Plus, the axles are now serviceable, whereas the older models weren’t. The best change is the redesigned rubber elastomers system. It’s no longer large and shaped odd like the last version but is smaller and diamond-shaped. The good news about this is that other elastomers no longer need tools to change them.

What are our favorite features?

  • This suspension seat post is excellent for backpacking or dirt-road touring. We want the single bolt saddle installation process and how easy it is to change the rubber with no tool needed. The parallel design doesn’t change the distance between the seat and pedal.

What could be better?

  • The seat is a bit too high when you use the extra-large rubber, The suspension seat post is more expensive than similar models, and the design is a bit disappointing if you like the sleeker design. Another thing is you may have to adjust your riding style so it doesn’t bob up and down so much.

The gravel of the seat post is 20mm vertical + 15mm horizontal. This works well for the majority of riders.  It has a mini insert of 90mm and is recommended from riders from 176-220 lbs.

We chose this damping seat post because of how highly absorbent we found it to be. Even on our long rides, we didn’t feel sore with this shock-absorbing seat post. Even over larger bumps, they didn’t have a significant impact on our ride. If you live on a dirt road or frequently go up and down hills, this suspension seat post helps you feel in control of your bike. It was easy to install and easy to adjust to fit your weight. It’s made of high-quality materials and is super sturdy.   When trying it on an e-bike, we were pleasantly surprised at how smooth the ride was once we adjusted it properly to fit the rider’s weight.

Why are we impressed?

  • The ease of installation was the first thing we noticed—the high-quality material it’s made from and how durable it is. It’s lightweight and just sturdy enough to make your ride smooth. We like the limited weight range. It also comes with a 2-year warranty so you can buy it with confidence.

What negatives must you be aware of?

  • The limited information about it on the web. If you’re on rocky terrain, you will bob up and down more mainly because it’s made to absorb impact from more minor bumps, which is why this is the best suspension seat post for bikes that are ridden on gravel and dirt roads.

The built-in spring coils plus damper rubbers absorb vibrations and help you ride longer distances because you are no longer getting beat up during the ride.

What cons did we find?

  • it’s pretty loud when riding on the road, making a squeaking noise. Although installation is simply getting the seat in the correct position is more complicated, I’d recommend using a level. The installation instructions are a bit wordy, and work clean and patiently is not needed. Without a seat cover, you slip on the saddle horn frequently.

Things to Consider

What is a suspension seatpost?

A suspension seat post is a special part of a bike that has a suspension system. Unlike the standard seat post, the suspension system does not stay stationary but instead moves vertically, making it more comfortable when riding on rough or bumpy terrain.

Type and Use

Which type of seat post do you want, and what do you use your bicycle for.
