  1. I have a friction-powered headlight. Rather than ride another summer
    grinding energy for a headlight I don't use from about March to October, I
    bought myself another wheel. Nothing fancy, a Shimano 105 hub, some sort of
    ordinary Mavic rim.

    Wow. It's like another bike. I probably picked up at least 10% on my speed,
    I swear. And climbing hills is like a dream.

    A friend asked me, "does this mean you aren't going back to your friction
    hub headlight?" I replied that, since nearly all my October to March miles
    are in the dark, commuting, that I'd switch back without hesitation. I
    really do like the convenience of an always-available,
    never-have-to-recharge, can-never-overcharge light.

    But dang, I can't believe I rode for two summers with it. Yeah, on Thursday
    night I came back late, and I used just the cateye see-me light. But I'm
    usually never riding all that far under those circumstances (in these, less
    than 5 miles, in a street-lit urban environment), and it's well worth it not
    to have the drag.

    What is a ***friction*** powered headlight? That reminds me of those
    1950's type generators that just rubbed against the tire and did take a
    lot of effort for a little light. A center hub generator is supposed to
    take almost no power if it is not being used.
    Curious.

    I was wondering the same thing, Claire. Besides, doesn't the ***friction***
    drive generator lift off the tire when it's not needed, resulting in NO
    power loss?

    I believe she's talking about a front wheel hub generator.
    Those things are reputed to inflict somewhat more drag when
    switched off, than when switched on.

    As for your "1950's type generators that just rubbed against
    a tire," the modern versions don't require much work at all.

    Even the old Union generators (of which I have a few) don't take
    that much effort, either. At least, not for a stronger rider.

    By "friction powered headlight" and "grinding energy for a headlight I
    don't use" do you, perchance, mean a hub generator? If so, what kind of
    hub generator? I've got a Shimano 3N-71 hub generator powering my
    headlight, and it certainly doesn't cut my speed by any 10%. If your hub
    generator is a cheaper model, treat yourself to a higher quality
    generator hub like the 3N-71 or a SON (Schmidt Original Nabendynamo).

    Or have you just been riding around with your bottle generator engaged
    during daylight hours? :-D

    Or,
    Maybe she turns off her headlight by shorting it out. Ouch, what a load
    that would be.

    Using narrow tires at 100 psi you will also fly faster if you are not

    Yes, she has a Shimano hub dynamo.

    I've never really noticed any extra effort. My average speed declines a
    little, but not enough for me too care much about. Especially in winter
    when I'm already riding slower because of poor light and extra wind drag
    from extra clothing.

    A Dublin lawyer died in poverty and many barristers of the city subscribed to
    a fund for his funeral. The Lord Chief Justice of Orbury was asked to donate
    a shilling. "Only a shilling?" exclaimed the man. "Only a shilling to bury
    an attorney? Here's a guinea; go and bury twenty of them."

    Right, rechargable lights are suboptimal IMHO. And with the money saved
    from not replacing them every year[1], I've already payed for my dynamo
    wheel + light.

    I really should dig out my other front wheel. It's not so much the
    drag, but I could do with a little less weight. My bike is somewhat
    heavy admittedly...

    For reasons beyond the comprehension of most people, many fixed-gear riders insist
    on riding with no brakes. They just fight the pedals and hope that their rear tire
    alone will stop them or that they can dodge.

    When informed of this bizarre cult, a friend of mine remarked that riding with
    deliberately ineffective braking offers all the exhilaration, sense of
    superiority, and irresponsibility of driving drunk without the hangover.

    I haven't thought of a good rebuttal yet.

    If you ever want that drag back for nostalgia, just do as I did -- buy
    a new set of wheels and then neglect to adjust your brakes before you
    take your first spin. Amazing how a gently-rubbing brake pad can make
    any day seem windy and any hill seem like the Koppenberg.

    mechanic...)

    I don't think Claire has a Van der Graaf generator
    on her bike. Just an erstwhile hub generator that
    impinged a drag and weight penalty during daylight
    hours. Now she's got a lighter, free-er rolling
    front wheel and she detects a noteworthy difference.
    Same as switching to a pair of lighter tires.

    A Van der Graaf generator would be fun, though --
    make yer hair stick up through yer helmet holes.
