How To Stop Your Brompton unfolding when not fully collapsing the saddle Brompton seat post mid-stop stops the bike unfolding when folded, letting you push or roll the bike like a P/T-Line model without it unfolding, preventing the annoyance of Velcro straps or the seat post dropping completely; it clips on easily, works with most models (C-Line/A-Line), and is a simple solution for easier handling. This unit is designed around the rear lower fork legs being 43 -44 mm apart. Printed in TPU so is more forgiving than hard plastic PLA or PETG ones If your for legs differ in width just message us and we can design and print a custom one for you
