2427.0. "Heavy Weight Rider" by TIS::GRUHN () Wed Oct 07 1992 16:03

    In a few past notes I have mentioned that one of my "Hobbies" is
    collecting what once were nice bikes from the metal heap at the
    town dump and restoring them with other similarly aquired parts.
    The last one, which my adult daughter now has, is a Bianchi from
    the cottered crank era, and a very nice bike it is.  She has 
    given me an order for a dumpcycle for her SO so that the two of 
    them can engage in recreational cycling together when the weather
    be good and the spirit moves.  I will be delighted to build up
    something suitable.  Now here is the question.  He is about 6'2"
    and weighs somewhere around 285-300 pounds.  Not fat, but a BIG
    BOY.  Being as how the machines I generaly get to rebuild are
    similar to the Bianchi mentioned above, what I am wondering is
    whether this sort of frame will handle that sort of bulk.  As
    far as frame size goes, I'll just wait till a good tall one comes
    up.  We are talking steel tubes and lugs and probably steel rims
    as well.  I know what to look out for regarding frame dents and
    rust and other potential structural hazzards.  I just don't know
    what the load criteria are.  Can anyone out there give me some
    idea what the limits are?

    	Bill,
    
    	For the record, I'm 6'6'' tall and weigh about 285 pounds.
    	I've ridden a TREK 1400 aluminum bike since 1990. I run
    	36-spoke alloy (not steel) wheels with 28 mm clincher tires.
    	I've never had any problems with this bike or this setup.
    
    	I used to think I had to have a bomb-proof bike to do any
    	riding at all. I don't feel that way anymore. Obviously,
    	I could lose some weight, which wouldn't be a bad idea.
    	Now, however, I seldom think about things like "Will the
    	bike hold me," etc.

    Stick with aluminum rims, if you can find them at the dump.
    The real strength of the wheel is in how well the spokes are laced.

    See also Mr. Perez's note 1233.0, particularly the statistics in
    the last few lines.

    I wouldn't use any rims found at teh dump.  -- I know what I throw
    away.

    Seriously folks, thanks for the inputs.  It has put my alleged mind
    at rest regarding what a good, sound, hi quality lugged frame can
    take.
    
    What I have frequently observed at my favorite used bicycle emporium
    is that a large number of cast aways are/were decent bikes which have
    had the front or rear wheel rolled over by a car in some driveway.
    The rest of the bike will be in fine fettle except for a wheel which
    is bent rather badly.  The other wheel will be from ok to like new.
    It is truly wondrous to observe just what falls prey to this throw-
    away society.  Doesn't matter a whit what kind of shape something is
    in to SOME people.  If they no longer need it, or a new model/fad comes
    along, take the old one to the dump and go buy the newest.  So they roll
    over a wheel and it gets bent enough to no longer turn.  Chuck the
    whole bike and buy a new one.  They seem to think that either nothing
    can be repaired, or that, oh never mind, I'm getting het up about this.
    BWT "het up" is an archaic expression carried over from my youth a long
    time ago and has nothing whatever to do with sexual orientation or
    preference.
