CHOOSE THE RIGHT SIZE -- Please check the diameter of the bike seatpost before purchasing. Incorrect diameters will not fit; 27.2 mm/31.6 mm are different diameters and are not interchangeable. Remove the old seatpost from the frame and you can see the diameter of the seatpost.
INDIVIDUALIZED ADJUSTMENT -- Our bicycle seatposts support riders weighing up to 200 kg/440 lbs.

For heavier riders, tighten the bottom nut clockwise; for lighter riders, loosen the bottom nut counterclockwise.
APPLICATIONS -- The high-strength aluminum alloy Goucrro shock-absorbing bicycle seatposts are suitable for most mountain bikes, gravel bikes, hybrid bikes and e-bikes; the surface of the seatposts is anodized to prevent rust and durability, which greatly improves the product's service life.
