Any US sources for 550mm seatposts? (31.6 or 31.8 mm diameter)
I see some expensive CNC seatposts for over $100 but wonder if anybody sells the cheaper ones like are supplied on many folders.
I wish there were easy sources for folder-suitable seat posts in the UK; I've not found anything for my brompton. I'm not going to spend £50 or whatever on an alloy seat post.
I made a telescoping seat post from parts I had lying about. Found an old 25.7mm seat post that fits inside the folder's 31.8mm post. Added an old quick release and now its good to go.
