Factors to Consider while Buying the Best Seatposts

All Seatposts are meant to do the same task of holding the saddle and reducing the effects of vibrations as much as possible. As consumers, we usually hardly notice the Seatpost and ride the bicycle anyway. It is beneficial to know what a Seatpost does, what kind of Seatpost suits you and what are the things you must keep in mind when you are investing a significant sum of money on an accessory for your bicycle. Though it may seem as ‘just another rod on the bike’ – it determines how comfortable it is to ride your bike. Now that you’ve already read the best Seatpost reviews keep reading to be aware of some factors to consider in order to ensure you are satisfied with your purchase.

Sizing

The most crucial factor to measure is the diameter of the Seatpost. If it is not compatible with your bicycle measurements, then the purchase is a waste. The majority of modern bikes accept Seatposts with a diameter of 27.2 mm, 30.9 mm, or 31.6 mm. The wider the post, the more power transfer and resistance to failure of functionality. The narrower the post, the more comfortable over rugged terrain.

Material

Commonly, carbon fiber, titanium, and aluminum are the 3 materials that Seatposts are made of. Titanium proves to be expensive but rewards the user with a lightweight product and breeze-like riding experience. Whereas carbon fiber is also light, but they cost more and require ultimate care during installation. Carbon fiber is the preferred material due to its shock-absorbing characteristics. However, many MTB and trail riders would opt for aluminum Seatposts due to their sustainability and end endurance.

Layback

This is the distance between the middle point of the Seatpost and the center point of the saddle rail cradle. Reach, comfort, stretching, body posture – all these factors are impacted by the layback. Lesser the layback, lesser will you have to stretch to reach the bars and vice versa. This factor boils down to personal preference – people who can not work with an inline post eventually turn to a layback to adjust their riding posture as desired.


Frequently Asked Questions

What is a suspension Seatpost?

A Seatpost with an internal spring system or any sort of shock-absorbing mechanism is a suspension Seatpost. This comes in handy to bicycle riders all over the world. It helps them ride on rough terrains, be it mountain ranges, forest road, or poor roads. A suspension Seatpost basically allows riders to sit on the bicycle for longer durations.

What is a dropper Seatpost?

This is a comparatively new discovery in the bicycle industry. Rather than manually adjusting the Seatpost, the dropper Seatpost lets the rider adjust the Seatpost via the push of a button or ball present around the handlebars. This enables them to ride their bikes for longer durations without the need for stopping and making manual adjustments by hand.

What size dropper Seatpost do I need?

You need to make the calculations yourself unless you take help from a bicycle professional. Check your frame’s seat tube and measure its diameter with a relevant instrument. Commonly you will measure 30.9 and 31.6 mm. Also, make sure the height is based on the maximum extended length of the post, as no height is considered too low.

How to determine Seatpost size?

To get inch-perfect measurements, you need to measure the length of the Seatpost collar to the seat railing. Use a calibrated caliper with a tolerance of +/- 1 mm. Check the length of the Seatpost holder on your bicycle – ranging from the lowest possible point to the maximum elevated height of the seat. This allows the Seatpost length to vary and the sliding mechanism works just fine for undisturbed functionality.

How to install dropper Seatpost?

Firstly, slide the cable along the lever mechanism that is attached to the fixed barrel resting inside. Remove the cable from the other side of the housing (unless you have an internal cable system). Trim the cable to your desired length and install a removable barrel end; please use a cable cutter and not scissors. Now the barrel end should seat itself right to the bottom of the dropper, and the post would have fit comfortably in the frame.

How to adjust suspension Seatpost?

The safest way is to detach the Seatpost from the frame and work on it. Turning the post upside down, you will see a dust cap with a hex like opening that should be 6 mm in diameter. By turning the Seatpost clockwise, you will make it stiffer and more rigid, whereas anticlockwise would make it much softer.

How to cut carbon Seatpost?

For this kind of task, you must use a carbon-specific blade to get the job done. Take note of the minimum insertion amount and cut down from the Seatpost collar mark. You can also wrap the carbon Seatpost in electrical tape and then use a significantly sharp-toothed saw blade. Make sure not to breathe in the dust as the particles can get stuck in your chest and lead to fetal abnormalities.

Wrapping Up

There is mild controversy whether to use greased carbon Seatposts or not, but there is no conclusion as yet, so if you like it, go for it, but be ready for anything. Now that you have read the best Seatpost reviews, read about vital factors to consider when buying a Seatpost, and got an answer to most of the frequently asked questions, you are equipped with sufficient knowledge to make your purchase. Do you need a Seatpost for Mountain biking? Road biking? Desert biking? Biking for the daily commute? Or for your kid or wife’s comfort? There are options within all price ranges for specifics as per the requirements you have.
