  1. I faded out of cycling temporarily about the time when paired spoke patterns
    made their appearance. Old school says that few spokes are bad news unless
    you are a feather weight, but they seem quite popular on road bikes.

    So is old school correct, or is there new technology that makes these OK? Do
    the newer aero rim profiles make that much difference?

    In spite of my size (6'-6" 200+ lb) and high mileage, I have never used
    anything resembling a tandem wheel on my retired DF bikes, on or off road.
    In fact, they would more accurately be described as "race day wheels" by
    smaller riders than me.

    On a DF I naturally used supplesse to spare my wheels, but not an option on
    my Phantom II. Even the smooth clean roads I ride now have the occasional
    pothole. The side loads are nothing (compared to DF anyway), the 20" wheel
    is stronger (so I have read), the frame has lots of passive suspension, and
    I am thinking of a Pantour up front too.

    Given all this, the Phantom II comes with wheels suitable for a tandem for
    elephants. Overkill by a big margin I think. But how far should I consider
    going for better performance?

    They are OK for some folks. From an old school heavyweight (240#), like
    myself, I'd say less spokes are an invitation to more trips to the shop.
    However, carrying extra spokes and a wrench might be an option.

  3. I like watching American Chopper (humor factor when it comes to warped
    priorities) building rims; but why mess with a tried and true spoke
    pattern?

    Someday I will try a wild pattern of Mylar- covering the spokes- maybe
    cut with a dull knife...

    You'll find that the rims on those minimal-spoke wheels are massively
    heavy-duty. In general, the paired-spoke wheels are heavier than their
    more conventional counterparts.

    I've built wheels with rims that are 2/3 the weight of the the tall
    paired-spoke-style rims (400 grams vs. 600 grams) and they've held up
    great despite my being your size (I'm 6-foot-4, 220 pounds). A
    36-spoke wheel built with a Sun M14A rim and double-butted spokes
    should be lighter and more durable than a minimal-spoke wheel.

  5. Good enough for me, but the choice of rims for 20" size (either) seems
    pretty limited, so it may be a bit of a mute point. Narrow 26" are a little
    better.

    How about tire width vs rim width? any formula there? At the moment, my
    stock rear tire looks like it belongs on a much narrower rim (the rim is
    almost wider than the tire).
