manufactured using the porthole method to produce a seamless, strong


tube. Aluminum tubes with walls too thin to be extruded are


manufactured by rolling and welding narrow aluminum strip. Welded


tube is fairly inexpensive and is used for light support products such


as lawn furniture, toys and drains.




His 6061 and 6063 aluminum tube is all extruded.




In mitigation I might add that all of the stainless steel tubing I've


seen in the past 10 years, or so, has been welded.






I replaced damaged tubes on a 1919 JIC race bike which had

thin wall (0.9)steel seamed tubes. With brazed seams no

less. Fairly light frame, probably the bees knees for 1919.

Didn't weigh it but not bad, maybe 5lb or so.

The first plant for making thin wall seamless tubing seems to have
been opened in 1895, apparently essentially to support the bicycle
making industry as the article states that "As bicycle manufacturing
gave way to auto manufacturing, seamless tubes were still needed for
gasoline and oil lines"

for some good replacements.

Are you serious? Aluminium is not good seat post material? What about
the millions of such
seatposts in use?

Apparently no one of my seatposts is any good, since they're all made of
aluminum.

I'm not looking forward to spending $204 apiece to get them up to "sms"
standards. :-(

I was thinking about buying a Deda Zero 100.

http://www.chainreactioncycles.com/a...k/rp-prod84212

Nothing like $200.


No, it is A$ 82.34 plus shipping. Seems like a lot of money for a seat
post. Even one that is infinitely adjustable.

But far better than US$ 200.00 :-)


Better still, I ordered one on ebay for $55 including postage!

BTW the "Around Astabula to About Akron" region was owned by
Connecticut from the 1600s. It was the state's Western Reserve.

Yep. It was also owned by Virginia, depending how you read the
colonies' charters. Apparently, the various kings of England were less
than precise when granting charters to colonies, so there were
"debatable lands."

The solution for the brand new country was to turn most of those lands
over to the new Federal government, with rules for using them to
generate new states. Like Ohio, for example. But Connecticut wanted to
reserve a bit of its western land, either to pay back folks whose homes
had been destroyed in the Revolutionary War, or to sell to investors to
help finance Connecticut schools.

I live in the Connecticut Western Reserve area of Ohio. Many of the
small towns feature New England style architecture and village greens in
their old centers, brought in by settlers from Connecticut. Kinda charming.
