Zoom Suspension Seat Post - Black, 31.6x350 mm

Product Information

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. If you want to fit a thinner seatpost to your bike, you can buy shims that fit between the frame tubing and the seatpost. You can’t fit a wider seatpost than that your bike is designed for. 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? One of the most important considerations when buying your next seatpost, is the diameter of the seat post - and how this diameter works with your bike frame. The diameter must fit the internal diameter of your frame - which is typically 27.2mm on a standard frame, or either 30.9mm or 31.6mm on an oversized frame.

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.The seatpost is one of the most important parts of your bicycle. A good seatpost supports the majority of your weight on the bike and must be able to withstand that weight while maintaining the appropriate angle for your ride and without moving. While the seatpost your bike comes with is likely adequate for the job at hand, for those looking to upgrade their kit or replace one that broke, a new seatpost offers an opportunity to cut weight and even add some suspension to reduce vibration, making it easier to ride farther. Best Bike Seatposts 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. 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. Seatpost length ranges anywhere from around 75mm to more than 400mm, though most posts come in lengths between 300mm and 400mm.

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 Best Lightweight Gravel/Road Dropper: FOX Racing Shox Transfer SL 27.2 Performance Elite Dropper Seatpost Most saddles have round rails, whereas some have oval rails. You may need a seatpost with a clamp design that’s deeper to accommodate oval rails. An older standard popular on road bikes, 31.6mm seatposts have mostly been superseded by 27.2mm-diameter posts. They’re still found on some road bikes and many mountain bikes though.

A narrower post will typically be lighter and can offer improved comfort, because it’s able to flex more easily than a stiffer, oversized post. 30.9mm seatpost 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.

There are varying degrees of complexity in getting the clamp set up and adjusted properly, from slightly awkward to downright infuriating. The Twin Link clamp uses two bolts with expanding wedges to adjust saddle angle and is easily accessible from the sides below the rails. Part of the Enve Road range with the Enve Road bar and stem, it's unsurprisingly top-level componentry with a top-level price to boot.

Fizik Cyrano Seatpost

Round seatposts come in several different diameters, to fit in different-sized seat tubes. If you’re changing your seatpost, make sure the post you’re replacing it with is the correct diameter. The longer seatpost length of mountain bikes means rigidity and robustness are important, whereas with the shorter seatposts on road bikes, compliance and ride comfort are greater priorities. 34.9mm seatpost
