Can any seat clamp be used or is it unique to bromptons?

Unique.

I'm not saying you couldn't get a standard one to work somehow, but the B one fits a cutout in the seat lugs.  If you just want a non-latching version you can junk the latch bits.

Will search ebay for a seat and clamp

For the dickheads who only work on conventional bikes can somebody explain why you couldn't put a Charge Spoon on the stock post with a stock 5 piece clamp?

Well that's the more blunt way of putting it but as usual he's dead right.

Not if you take the first few posts literally . . .

Is there something about the top of the stock Brompton post that I'm not seeing ?

They are talking about the QR clamp/ lever for the seatpost, not the bracket that mounts the saddle to the seatpost.

By Gattopardo's replay* - and that he's about to collect a Brompton that's missing its saddle - I kind of made the assumption he was talking about the saddle. D'oh!  ;D

ETA 'REPLY' bloody autocorrect!

I am talking about the seat clamp.  Not the seat post clamp.

Or am I using the wrong terms?

I'd call that a saddle clamp, but the Brompton term appears to be 'Pentaclip'.  A seat clamp is probably something even more proprietary and squeaky, that you'd find on a recumbent, but it sounds a lot like 'seatpost clamp', which is one of the Brompton's known quirky components, which is why we all assumed you were talking about that.

The Brompton one is clever, in that it can be twiddled round to adjust the height.  No idea about the diameter of the post and compatibility thereof, but it certainly fits standard saddles.

Bromptons (unless extremely heavily modified) don't have seats, they have saddles.

(Don't ask my why seatposts aren't called saddleposts.  Probably historical reasons.)

Your two pictures are functionally interchangeable, whatever you want to call them.

You sit on a seat but you straddle a saddle.

Because it would look wrong? ;D

No reason why not the saddle clamp fits normal rails

The saddle clamp is standard providing you can get one in the right size.  The seat clamp isn't.
