Bike seat posts for MTB, road bikes, city bikes & more

Whether you are building your own bike from scratch or you need to replace a part on your bike, Bikester.co.uk has a huge range of bicycle seat posts that suit every type of bike, including road bikes, mountain bikes, city and touring bikes. More than just a pipe that attaches your seat to the bike, upgrading your bike seat post and having the seat at exactly the right height can boost your performance, reduce weight from your bike and make sure that you have optimal comfort during challenging rides.

Bike seat posts

What to look for when choosing a bike post

A bike seat post in its simplest form is a tube or pipe that connects the saddle to the bike frame. The length can then be adjusted to suit your dimensions and requirements. Having the right seat post is essential to ensure that you have a comfortable ride and you don’t experience any unnecessary strain on your back or neck.

There are a number of different types of bicycle seat posts that are engineered to suit different needs, whether you are on your daily commute from A to B, racing down hills or tearing across the countryside. Most bike seat posts are made from aluminium or carbon. The most popular material is aluminium thanks to its overall long-lasting service life and flexible, lightweight properties. Carbon-fibre is more expensive, but is more lightweight and comfortable due to its vibration-absorbing characteristics.

While most of them follow a similar form and function, there are key elements to think about when you are choosing the right seat post for you:

  • Diameter: the key feature to consider when you are looking for a bike seat post is the diameter. There are variations on the diameter of bike seat posts, but most modern seat posts, for both road and mountain bikes, have a diameter of either 30.9 or 31.6mm
  • Length: it is generally agreed that a longer post offers more comfort for your ride. However, the length is also dependent on the size of the frame and rider’s own specific dimensions (inside leg length). It is important to have enough post still remaining inside the seat tube (or frame) to avoid the risk of cracking the seat tube (most posts are marked with a minimum insertion line to help avoid this)
  • Shape: bike seat posts either come in straight or layback form. Straight, as the name suggests, has no bends, while layback has a shallow bend which places the saddle further back. This is normally down to the rider’s personal preference, and usually cyclists opt for one or the other and stick with what works for them to avoid repositioning and causing discomfort
