A seatpost needs to fit your frame exactly, hold your saddle securely, and it will also influence how much road shock and vibration is transmitted to your backside. We have compared the attributes of the three most common materials.
Easton?s EA70 is a top-quality aluminium seatpost, and is still under half the price of the others on test. A bigger investment gets you more advanced materials like the monocoque carbon Ritchey WCS or the 3/2.5 titanium USE Alien. Ritchey?s post is lightweight, but the high-gloss finish is not durable compared to the shot-peened aluminium or brushed titanium. Attention to detail on the clamp goes in Ritchey?s favour.
It?s maybe not as simple for small adjustments as the Easton, but it?s less fiddly than the USE, which tilts as the bolt tightens. The USE is very light, but it?s only 27.2mm diameter, so it requires a shim for other frame sizes. Both Easton and Ritchey are available sized to fit directly. Expect the harshest ride from the Easton and more comfort from titanium, but at a price.
The Ritchey WCS carbon gets our vote by a whisker. Beautiful monocoque construction, good secure clamp and lightweight, it ticks all the function boxes with no complaints for comfort either.
