Only time will tell.  Dahon design flaws can show up
after a while. For example, I was surprised to find the
spoke nipples on my relatively high end Dahon Speed 7
were aluminum -- discovering this only after stress
fractures dislodged the spokes. Why would the designers
choose failure prone aluminum over the standard brass
nipples? I was luckier than my friend, who's aluminum
Dahon frame also developed stress fractures. Over time,
many of the nuts and bolts rusted on various parts of my
bike rusted. The Speed 7 looked good when I bought it.
Over time, the design flaws blossomed. I have bikes that
are older, and held together much better.


The Ancients actually knew something:

I'm curious about the age of that advertisement.

As I understand, during the first huge bike boom of the
1890s, steel had the same high tech cachet as titanium or
carbon fiber has today. It was still relatively rare and
pretty expensive, even if far cheaper than it had been in
(say) the 1850s.

So I wonder if the ad was from a time when they were
bragging that it was new, or from a time (kind of like
today) when they were bragging that they don't need none of
that new-fangled aluminum?


It was indeed touting a technological breakthrough.

The first bicycles were seamed steel tube brazed to cast
iron joints. Raleigh was first with "The All Steel Bicycle"
having developed bulge-formed steel bottom bracket shells to
go along with their pressed steel lugs and thimble crown forks.
