My 2007 6 speed came with the poor Zefal others have mentioned.
It fell off and jammed the rear wheel on a poorly surfaced main road through Hereford and has never been replaced.
The titanium tip above is great as I'd forgotten that pump weight was sacrificed in the lightweight Brompy packages.
Unless you intend to ride pole to pole on yours, a decent set of tyres, bus services or short pushes mean it's not worth carrying a pump, whether you're buying Titanium or steel.
