The PNW Components Loam Dropper Post (31.6mm diameter, 150mm travel) is designed for mountain biking and offers a nice balance of features for riders wanting adjustable seat height on varied terrain. One standout feature is its tool-less travel adjustment, allowing you to easily change the seat drop by 25mm to fit different frame sizes or personal preference without needing special tools. It’s made from aluminum, keeping the post lightweight at about 1.6 pounds, which helps avoid adding unnecessary weight to your bike.
The air cartridge lets you fine-tune air pressure for a personalized feel, which is great for comfort and control. It is a solid choice if you want a durable, adaptable dropper that works well across a range of mountain bike setups, especially if you’re comfortable installing the lever system yourself or upgrading existing parts. The 3-year warranty adds peace of mind about its quality.
Many riders find it reliable and effective, though beginners might want to consider the extra steps needed for full setup.
The EXA Form 900i dropper seatpost is designed for mountain and e-bikes, offering 150mm of travel which is good for smooth height adjustments on rough trails. It features a 31.6mm diameter, so it's important to check your bike’s seat tube size before buying to ensure a proper fit. The post supports internal cable routing, which helps keep the bike looking neat and protects the cable from damage. Height adjustments are done via a remote lever, letting you change your seat position on the fly without stopping.
Made from durable 7075 aluminum alloy, it balances strength and lightness, with this particular 445mm length version weighing about 870g. This weight is typical for dropper posts with this travel range, though there are lighter options if you prioritize minimal weight. Installation is straightforward, and helpful videos are available, which is great if you're not very experienced with bike maintenance. It comes with a lifetime warranty against defects, which adds confidence in its durability.
One drawback is that the remote cable length is fixed, so bikes with unusual layouts might need adjustments. While the post performs well for multi-use mountain biking, riders seeking ultra-lightweight or very high-end features might want to look for premium brands. This seatpost is well suited for riders wanting reliable dropper functionality with clean internal routing and solid build quality at a reasonable price.
