There are Campy NR record brakes still in service from the '60s with OE springs. SMS probably just has a missing sleeve or poor lubrication. It's possible a spring went bad, but really unlikely. -- Jay Beattie. |

Now a lot of leftist Californian polticians are essentially saying "Well, yeah, that was a long time ago. Now we see that differently and we find that to be ok! To hell with federal law". -- Regards, Joerg http://www.analogconsultants.com/ |

If you want taxpayers to buy a kiddie path where you ride your bicycle, that's hardly conservative. 3. National health? YGBSM! The regulation is bad enough but actual health care really? Check out the wonderful results of BIA hospital system. Over a hundred years of rank incompetence, fraud, theft, waste and error. Good luck expanding that. -- Andrew Muzi www.yellowjersey.org/ Open every day since 1 April, 1971 |
