I've already posted this in the Commuting thread (dunno why but there ya go) but didn't get any replies so I've re-posted here where it's probably more appropriate.
The 2007 range of higher-end Dahon folders include a BioLogic Zorin PostPump as standard, which seems like a great idea. I'm sure I've read somewhere that post pumps are not a good thing as the seat post is weakened. Is that the case?
I'm possibly going to buy a Dahon Mu P8 which (I think) has a BioLogic Zorin PostPump as standard so I'd like to know if here are any issues with this particular post pump and with post-pumps in general. Are there a number of manufacturers of post-pumps out there? A quick Google search seems to indicate just the one.
