I was doing my occasional maintenance -- which was extensive because the BB, RD and FD had gone to sh**. The pulleys had shark's teeth, and the FD cage had practically worn through. The BB was shot, and the bike was creaking like crazy, including a snapping sound that made be a bit nervous -- and for good reason. The left side chain stay had practically cracked all the way around. Waaah. Bike two down (Supersix in roof rack incident). I'm down to one bike -- the Roobay. Time to go on a buying spree for a fast commuter. -- Jay Beattie. |

There's someone who put turbo props on them, even. They're not pressurized, so they dont' suffer from pressure cycles, and they structure is such that every part can be replaced, without too much other changes. -- sig 22 |

Back in 1978 or so, I designed and made my own handlebar bag. The bags I had at the time had a 1/4" steel hanger frame that looped under the stem and over the handlebar. I decided to try an aluminum hanger frame on mine. I used a 3/8" rod of 2024, annealed it, bent it into the pretty contorted shape, then heat treated it again. I'm sure it saved me as much as an ounce. I wondered how soon the aluminum would fatigue. But it's been fine for 40 years now. Time to go on a buying spree for a fast commuter. Isn't that an oxymoron? -- - Frank Krygowski |
