Keyhole hubs?
"Jim Rogers" wrote in message
... If not, why not? Seems that Phil Wood hubs are pretty close, but they don't have the keyholes. Of course, Sheldon often said that, with their radiused spoke holes, spoke breakage with a Phil hub was "unheard of." So maybe keyholes are unnecessary... I think you've got the answer there. Spoke breakages aren't the common thing they used to be, both as a result of improved materials and improved building technique. So keyhole hubs are now a solution in search of a problem. (I use 36H on a touring tandem, and don't bother with spares. Granted, it's 26", but that sort of thing would be considered insane a few years ago.) cheers, clive |

I'd love for the answer to my question to be: "Sure, keyhole hubs allow you to easily change a spoke when it breaks every 10-20 thousand miles, but your radiused spoke-holed Phil hub provides such better spoke support that you won't have to change a broken spoke for more than 100,000 miles. So your hub is better than a Maxicar." --Jim |

Just kidding, you're probably right. Thanks for the info. --Jim |

Replacing a spoke is only a little faster with a keyhole than without
it - except when something else gets in the way. The cog issue has been solved by the cassette lockring. Since a broken spoke is a rare event, no one is likely to pay the extra machining cost for the miniscule benefit. Disk brakes could change this calculation... How many people even carry the right lengths of replacement spokes?? JG |

I'm questioning why there are not keyholes for spokes on the drive side of rear wheels, where freewheels (and cassettes) would be in the way. The cog issue has been solved by the cassette lockring. *Since a broken spoke is a rare event, no one is likely to pay the extra machining cost for the miniscule benefit. *Disk brakes could change this calculation... You're probably right. I use freewheels on Phil Wood hubs. For me, I thought keyholes might be handy (unless they cause more broken spokes than regular holes). It also seemed like it would be easier for those with cassettes, although less so. How many people even carry the right lengths of replacement spokes?? Many, according to bicycle touring message boards I read. --Jim |
