that was the last straw
"I've been using this seatpost for a year on some pretty rough gravel rides, and it just isn't reliable enough. Obviously, it gets shaken around, and I've even had a notch pop out on a simple pothole. And once that happens, the situation gets worse for the rest of the ride, which turns into a real nightmare—not to mention pure suffering. As you can imagine, I’ve tried various tightening methods and positions. Recently, it happened one too many times, hence my feedback."
