Some ago a friend said that a Brompton set pin would fit an my Moulton APB.
The one I'v now a too short.
So I tried it with Brompton Extended Seat Pillar,
It does fit fine. The wide bit goes under the collar on the bike.

I'm only 5'10" but found the original post a bit short. I considered the telescopic but bought this one for cost and simplicity. I once asked a fellow bromptonaut if his saddle could be pinched because of his telescopic quickrelease. He didn't know, tried it, and was alarmed to find that the top pin and saddle were easily removed. I know that brompton riders generally don't have to leave their bike anywhere vulnerable so may not worry about this. I looked quite hard for information on fitting this post but found none. However, with the saddle removed, it was a simple matter of slipping the old one out the bottom and pushing the new one up in its place. It's worth cleaning the new one with detergent and giving it a good rinse and dry to avoid any danger of factory oil making it slip when clamped. And I wonder if this replacement is just the tiniest bit smaller in diameter as I had to pinch up my seat clamp by about a quarter turn. As for the resulting saddle height whereas it was too low before, it's a smidge too high now at full extent. I may cut off about 20mm from the new length and flare out the bottom end so that I can pull it fully out and know it's at the perfect position.

Exactly the same as the stock post but longer - pedalling is far easier now I can get my seat to the right height!
