Building A Bicycle Dropper Seat Post

A maker known as [kane components] built a homemade bicycle dropper seat post from scratch, drawing inspiration from woodworking bar clamps. The design uses angled binding plates on a rail, a cable-actuated cam to release them, and an air spring for return. Reusing parts from a broken commercial post, the mechanism was thread-milled into a replaceable cartridge. Despite creative engineering, the build ultimately failed to work consistently — the binding mechanism couldn't reliably hold the post under a rider's weight — but the journey documents useful lessons in mechanical design, machining, and iterative problem-solving.
