1837.0. "Buying for a Pre-Teen, Safety or Lenght of Use?" by MUSKIE::VENTURA (Wherever you go, there you are!) Tue Feb 05 1991 11:32

    I have been shopping for a bike for my son for over a year.  He is
    12 years old, and has grown at least 2 inches during the time we
    have been looking.  Various sales persons have told us different things
    about "fit", when we first started looking a 19" or 48 CM frame was
    "OK", last night we found a PANASONIC AL-7000 with a 56 CM frame.  
    He currently has a 31 inch inseam, weighs about 100 pounds and is 5' 5"
    tall.  The salesperson had him straddle the bike.  With his feet flat
    on the floor (wearing shoes) the top tube touched.  I asked the sales-
    person if this was safe, and got the response, "He will grow into it".
    
    The bike is on lay-away, we live in Minneapolis, so my son will
    probably grow at least another 1/2 inch before we have them build the
    bike this spring (which could be 3-4 more months up here).  We will also 
    probably put thinner tires on the wheels (700 x 18) which will give him 
    additional clearance.  They have 54 CM availble, but the componants go 
    down one level (Currently Exage 400).  I want my son to be able to ride 
    the bike for at least 2 years, should we go with the 56 or the 54 CM frame?
    Also, I checked the Bicycling '91 buyers guide to see if we got a good 
    price ($294), but could not find Panasonic, are they still making bikes?  
    Since this is an aluminum frame I am a bit concerned about the warrenty.
    
    Thanks in advance,

1837.1SOME THINGS TO CONSIDERWMOIS::C_GIROUARDTue Feb 05 1991 12:2125
     Height alone cannot be the only consideration around the planning
    of growing into fit. While adjustments to stem and seatpost height
    may help with the leg length, upper torso growth is as important.
    
     In other words, you may be able to get by for two years depending
    on the the growth rate, but only if there aren't severe changes
    in torso length, arms (and legs). A fit kit will almost always
    recommend a "range" of frame size, e.g. 54cm-54cm or stem length,
    e.g. 105mm-110mm, etc... There is room there to play with anyway.
    
     Your problem is a tough one. 
    
     I'm almost positive PANASONIC is out the bicycle business. Someone
    else may confirm this. I think issues around warranty will be at a
    very low risk (unless there is a severe mfg.'s defect somewhere).
    If the shop has any reputation for customer service, they'll stand
    by the bicycle. It wouldn't hurt to ask them though.
    
     I'm a little over 5'6" (what a giant!) and my fit kit stated 53cm to
    54cm. My inseam is a little shorter than 31" however. Long legs for
    young guy.
    
     Just some input - not all the answers...

    Do you  have  to buy now? If not, why not wait till spring and see
    how much he's grown?

    I'd be careful about getting a bike that he'll "grow into" for two
    reasons.  The  first  is that he might stop growing. The second is
    that  if  the bike doesn't fit when he starts riding, riding won't
    be fun and by the time the bike fits, he won't be interested.

    If he's  growing  that  fast it might pay to buy (and then sell) a
    series of used bikes, one per year or two. That way the cost won't
    change much and he'll always be riding a bike that fits.

    If you do buy a new bike, I would buy one at the larger end of the
    fit kit range, and possibly buy a longer stem after a year to deal
    with his growth.

    [obligatory recumbent  plug:  a  recumbent  typically  fits a much
    wider range of height than a diamond bike.]

1837.3my 2�NOVA::FISHERWell, there's still an Earth to come home to.Tue Feb 05 1991 13:4511
    Yow, with that growth rate and the way kids grow anyway, any fit
    will change in 4-6 months.  Figure that in one 6 mo period his
    torso will grow and leave his arms behind, in the next 6 months
    his legs will grow faster than ...
    
    Just keep in mind that when you have to buy new shirts or new pants
    or something because he's outgrown everything, there may be something
    to change on the bike, too.  Also the more seriously he uses the bike
    the more seriously you should consider making changes.

1837.4Smaller = BetterGSFSWS::JSMITHChromed CannondaleTue Feb 05 1991 14:0118
    
    	If you really want to purchase a *new* bike then
    	I'd go with the smaller frame for a few reasons:
    
    	1.)   Safety.  He'll be able to control the bike better
    	      and be less susectable to injury on the smaller frame.
    
    	2.)   The seat height adjustment will keep him on the
    	      bike for a few years with a few stem changes.
    
    	3.)   Most pro's use a smaller thus lighter frame because
    	      they can ride faster (also stiffer frame).
    
    	Just my 2 c's...but personally I'd just buy him a new bike that
    	fits every year at a police auction until he either stops growing
    	or gets serious about racing.
