Some bikes, such as the Giant TCR, even have integrated seatposts that cannot be replaced. If your bike has D-shaped or aero seatpost, like the Specialized Pavé, it is unlikely you would be able to upgrade it without going back to the specific manufacturer. 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. How to choose the best road bike seatpost for you Are all seatposts the same? It comes in sizes from 24.5 to 31.6mm and is claimed to weigh 178g in the 27.2mm, 25mm-offset package – that's pretty light but not as light as the Roval. 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. The Twin Link clamp uses two bolts with expanding wedges to adjust saddle angle and is easily accessible from the sides below the rails. While quite a few carbon posts have a metal clamp head bonded on the top, the Enve post is carbon through and through. You may be looking for a simple weight-saving aluminium option or, for those who like to hit the trails, some of the best gravel seatposts use rubber-cushioning elastomers or mechanical pivots and springs to smooth out the bumps.Īt 300mm in length, the Enve seatpost is available in 0mm, and 25mm-offset versions. From damping to deflection, the best carbon seatposts can help soften vibrations and take the edge off impacts.īut that doesn't mean carbon is the only option. 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. The introduction of carbon to bike manufacturing was a game changer for seatposts. While you may be tempted to think the cycling world has got a little bit too obsessed with ticking all the boxes in the safety manual (although that is, unarguably, an important aspect), compliance in this scenario is a measure of the elastic deformation the seatpost can endure – which a key contributor to comfort.
