Most dropper posts enable you to lower your saddle by between 125mm and 170mm, while outliers start at 100mm and go as high as 210mm. In short, no. Seatposts are an area where bike manufacturers seek to make gains in weight, aerodynamics and comfort – so there are a whole range of different types that come with different bikes. It’s usually made of metal, even in a seatpost with a carbon shaft, although some carbon seatposts are one-piece and include a carbon head.

Some bikes even go as narrow as 25.4mm, Cannondale being a case in point. A skinnier post will provide a bit more flex, and therefore a slightly more comfortable ride, while a fatter one will be more robust and add stiffness for additional power transfer.

ULTIMATE USE 31.6 Internal Shim

Some seatposts, particularly those for road bikes, try to add in some sort of suspension or damping mechanism to reduce the amount of vibration that reaches the saddle—and ultimately, your rump. Some of these are passive, relying on the materials in the seatpost, while others are active, with joints, springs, and pistons. Dropper Mechanism The introduction of carbon to bike manufacturing was a game changer for seatposts. Not only can it help to reduce the overall weight of the bike, but the way in which carbon components are manufactured – by building up layers of fibres –can be adjusted to give it the perfect blend of compliance and stiffness. From damping to deflection, the best carbon seatposts can help soften vibrations and take the edge off impacts. and 31.6mm are the most common seatpost diameters, with 34.9mm also emerging as a popular size for mountain bikes. 27.2mm seatpost

The most common size on modern road bikes and gravel bikes is 27.2mm. These posts can be found on some MTBs too, although the size is confined mainly to a limited number of cross-country mountain bikes.Every brand seems to have its own take on the saddle clamp design, which usually includes a bolt at the front of the head and another at the rear, although some have just one bolt. Mountain bikes typically have a lower standover height than road bikes, leaving more of the post exposed, so a wider post is preferred to improve strength. 31.6mm seatpost As with all aerodynamic upgrades in cycling, it is a culmination of marginal gains that will start to make noticeable differences to your riding. So, yes, seatposts can make a difference but, in most cases, aero seatposts will come in a proprietary design to fit a specific bike, making upgrade options considerably limited. Do carbon seatposts make a difference? Modern bike seatposts are built from various materials, with alloy and carbon being the two most common. A quality alloy seatposts will boast a lightweight profile, whilst also benefiting from being durable and cost efficient. A high-end carbon post is a necessary component for serious cyclists looking to squeeze every last bit of performance out of their machine. Competitive cyclists needing to precisely adjust their seatpost height on the fly should browse our range of dropper posts.
