【★★★Double Check Before Buying★★★】Please confirm that the diameter of the seatpost you are about to purchase is exactly the same as the old seatpost on your bicycle to ensure complete compatibility. If the diameters are different, installation will not be possible
【★★★How to choose the length, 365mm or 580mm?★★★】365mm is suitable for / compatible with most bike types and riders, such as cruiser bikes, mountain bikes, folding bikes, and some e-bike brands like Aventon and Lectric; 580mm length is only suitable for / compatible with certain folding bikes with particularly long seatposts, such as Brompton and Dahon.
【A Better Cycling Experience】The widely used model SP12-NCX/SP17-NCX from a certain brand often results in a forward-backward displacement of the rider's center of gravity during cycling, leading to discomfort during prolonged rides. In contrast, Safortbikes suspension system adopts a verticalized design, ensuring the rider's center of gravity remains consistently perpendicular to the ground. This guarantees a constant riding posture, providing a more comfortable experience for the cyclist.
【Exclusively 4-Link Suspension System】Introducing our patented 4-links parallelogram structure for an unparalleled riding experience—unlike central compression, this design achieves a perfect pressure balance, delivering a softer and more comfortable ride.
【Reliable Suspension】This suspension seatpost has passed rigorous metal fatigue tests, exceeding 100,000 cycles in both vertical and lateral directions. While the seatpost primarily absorbs vibrations in the vertical direction, it's important to note that during sharp turns, significant lateral forces are generated. If the suspension system cannot withstand such forces, there is a risk of structural failure in the suspension system over prolonged use.
【Extreme Capacity】This suspension seatpost can maintain stable shock absorption performance even at minus 40 degrees Celsius (-40 °F) and supports riders weighing up to 198 kilograms heavy riders (436 pounds). In contrast, similar products from other brands typically accommodate only 140 kilograms (308 pounds).
【Specification】Suspension travel 50mm, offset 25mm, total length 365mm / 580mm optional, weight approximately 800g, made from aerospace-grade 6061-T6 aluminum alloy, manufactured in Taiwan.
【★★★Installation★★★】Please note, the clamp of this seatpost features a more secure and stable structure compared to the side-mounted clamps of common seatposts, so the installation method differs slightly. Please install the rear end of the saddle's rails by sliding them into the clamp of the seatpost (refer to the installation video on this page for details).
【★★★Usage★★★】 The default spring tension may not be suitable for everyone.If that's the case,you need to adjust the tension at the bottom of the seatpost to ensure the suspension works for you. Use '+' for tighter tension (suitable for heavier riders) and '-' for looser tension (suitable for lighter riders), to ensure the springs match your weight.
