However, if I was to shift into full pedant mode, the Oxford dictionary states that a derailleur is “a bicycle mechanism that moves the CHAIN out and up, allowing it to shift to different cogs.”, so perhaps I could stand by my original statement. |

I would, simply because you probably could get a chain guard the ceramic speed :-) Wonder if will ever see the light of day anger. |

They have far fewer gears and are very expensive. I have never seen anyone riding one, which makes me do some wondering. Andy |

Andy Well, of course riding around in a marina isn't quite the same as crossing the U.S. :-) But they guy did seem to ride it here and there daily. But think of an automotive timing belt. Every 50 - 70,000 miles? -- cheers, John B. |

I have my bike covered with a tarp, but the dust still makes it under the tarp. I have ordered a DasBike Bike Cover. It completely covers a bike. https://www.amazon.com/gp/product/B0...?ie=UTF8&psc=1 Andy |

The (only) good part about those turd dust hurlers is that they are so noisy I can usually hear them way before they get dangerously close to the spot of the parked bike.

Impressive how an stationary exercise bike (dust collecting) cover is selling almost as well at a close #22 -- should really be mandatory with each sale to fit statistics of stationary bike usage. |

What in the world are these leaf blowers? From the sound of them they must be something to remove leaves from your yard, but where do the leaves go? Into the neighbor's yard? Out into the street? It seems a real puzzle :-) -- cheers, John B. |
