I replaced the chain that I broke on Saturday with one I had in my
garage that I must have purchased five to ten years ago.

It has a connecting link and it says "Taya" on it. It's for 6,7,8
gearing. It seems okay, but I think that this is the first time I've
used a chain with a connecting link since childhood. I looked up Taya
and it's a big Taiwanese chain manufacturer.


I still have a Sachs-Sedis 7-speed chain on my road bike which I bought
from a friend as NOS, for $6 which was the old sticker price (the
sticker had already turned brownish). No link, mounted with hammer and
anvil as usual. To my utter amazement it doesn't show any measurable
stretch after over 2000mi and sometimes I really put the coals on
because of our hills. Even the old Wippermann chains could not rival
that. I am very religious about chain cleaning and lube though.

The old 5-6-7 speed Sachs chains wore out three days after the bike
was junked.


The Sedis (later Sachs-Sedis) material and Delta hardening process was
not only exceptional but unsurpassed down to today except for possibly
Record chains. That ended with SRAM.


Why is that? In the automotive world such an advance in technology is
kept and further developed, not rescinded and chucked back into the dust
bin. Well, usually.

For example, transmissions nowadays typically last the whole lifetime of
a car. 20+ years for us on two vehicles so far, for everything. Vehicle
owners would have a hissy fit if they had to swap out a chain every 5000
miles.
