Keeps Your Folded Brompton Locked Together
This small hardware kit is what stops your folded Brompton from trying to unfold itself when you pick it up. Bolted to the rear brake mounting nut, the lower stop disc acts as a bumper for the seatpost and a catch for the folded rear triangle, keeping the bike neatly compact for carrying, rolling, or parking.
If your original disc is worn, missing, or working loose, this complete replacement kit restores the secure “click” of a properly folded Brompton. The threaded plastic disc and included hardware make setup straightforward, so you can fine-tune the gap between the seatpost and disc for smooth operation without unwanted rattles.
