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" -- Cheers, John B. |

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. :-( http://www.rivbike.com/product-p/sp3.htm 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! -- JS |

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. -- - Frank Krygowski |
