Everything old is new again...
It seems that a rear suspension system using a flexing chainstay is
not a new idea after all. http://ah.bfn.org/h/pierce/pierce/source/7.html Later, Pierce would make automobiles and trucks. http://ah.bfn.org/h/pierce/pierce/ -- Typoes are a feature, not a bug. Some gardening required to reply via email. Words processed in a facility that contains nuts. |

They're probably Osymetrics, which are an anti-Biopace ring: http://www.osymetric.com/design.htm There are other non-round ringmakers out there.

There has been a recent discussion dismissing them as impractical but apparently apparently they were marketable. |

They were marketable. Major Taylor rode and won (lots!) on a shaft drive bike. But "marketable" doesn't mean better. Shaft drives are certainly less efficient than chain drives - i.e. they have greater friction losses, because of the two bevel gears. And if you want multiple gears, your shaft drive will need an enclosed hub gear, which is less efficient than a derailleur. As I understand it, shaft drives around 1890 - 1900 were seen as elegant and clean. The roads of the day were probably bad enough that a little friction in the drivetrain wasn't very noticeable. And most bikes had only one speed, so the efficiency difference wasn't as great as it would be today, competing against derailleur gears. While I can appreciate their beauty, I wouldn't want one on my bicycle. And I speak as the owner of a BMW shaft drive motorcycle! - Frank Krygowski |

I guess the difference is, the BMW has plenty of power to spare. ;-) Mark Hickey Habanero Cycles http://www.habcycles.com Home of the $695 ti frame |
