1651.0. "What is double, triple and qaud butted?" by SALEM::SHAW () Mon Jul 23 1990 09:12

    
    Hi there, 
    
    I am in the market for another mountain bike, and would like a little more
    info. Since I started with one and upgraded the components on it,
    my knowledge in the feild of frames is limited, I think I know 
    enough about componets though to make the choice there.
    Could someone explain what exactly is the process of double ,
    triple and quad butting. 
    I have narrowed my choice to two selections, One bike is chormoly
    tange dubble butted with mono stay and straight forks, that I can
    guess would be very precise and quick especially downhill but 
    would it be a little too stiff a ride for like a whole day out.
    The other one has and oversized frame, and the brochure says it
    is double, triple and quad butted.This one only wieghts 25.5 lbs
    as opposed to the first one that ways 28 lbs. How much of a difference
    does a few pounds make in climbing and is that realy the criterea
    to select a frame. I read in MBA that slightly heavier frames are
    easier to handle on downhill rides cause they don't bounce all over
    the place. 
    The bike shop that has these two bikes is located in the city so
    although I can test drive them around the store, I cann't really
    try them out on dirt.
                                                              
    Thanks in advance,

    If its a quality bike and the prices are in the ballpark then go
    for the lightest bike possible! I have a freind who has a Klein
    ATTITUDE and its got to be the best handleing easiest to ride MTN
    bike ever. The lightness allows MUCH easier climbing (after all
    you gotta go up it so you can come down it!) and I can't notice
    a difference in decending at all.
    As far as frame terminology goes all I know (and really care about)
    is the type of tubing being used and the geometry of the frame.
    chormoly tange is great for MTN bikes. All you might want to know
    now is the angles of each frame.
    And for DOUBLE, TRIPLE.... butted, I think its the process of makeing
    the tubing thicker near the ends of the tube where the heat of brazing
    may weaken the metal and thinner towards the center of the tube
    where the excess metal isn't needed. This process allows for the
    lighter bike.
    One more thing, I'll probably recive alot of grief about this but
    everyone has the right to know and form there own opinions so here
    it goes. I perfer steel over aluminum first because its easier to
    spell ;-) and second because on a MTN bike your gonna fall and your
    also gonna hit trees, sometimes are going to be harder than others
    and with steel its easier to fix than with you-know-what if you
    happen to break or bend something. This is my opinion and you
    should make your own judgement.

1651.2What are choices for a mid. priced MTB?SALEM::SHAWMon Jul 23 1990 11:4314
    
    Hi Eric, 
    >if its a qaulity bike go with the lighter...
    Well, it is not qaulity like Klein. It the new ATX 770 from Giant,
    The other (heavier bike) is the Monghoose I-BOC comp. 
    BTW, I am shopping in the Souther NH area, but will be willing to
    go to MA (ie the bike shop in Cambridge is advertising a sale)
    If anyone is familiar with New England area, what other options
    do I have for between $550. to $750.00 for a fairly decent bike.
    I do ride hard and take a lot of downhill rides, and yes I do fall
    occasionaly. As for the two bikes mentioned above, any damage to
    the frame and the manufacturers will replace the fram free of charge.

    Shaw,
    
    I have a Mongoose I-BOC Comp 1989, and my son has a Diamondback
    Asent EX.  The two bikes ride completely different. If you want
    to take my IBOC out for a test spin drop me a line. or call me 
    @242-2447.
    
    I am located in the Westfield plant, so if you are down here on
    business bring your bike shorts and shoes.
    
    I have a GREAT place to ride just up the street :-).
    
    There are things that I like better on his bike, and there things
    I like better on mine.
