    specialized m4.... what is it?!

    Whats up everybody. Wow, its been a while since I've been here. Alright I need your help, my buddy bought a Specialized M4 and uhhh.... what the hell is an M4?! I can't find a review for it. I've seen reviews for Specialized M4 hardtails, but its not a hardtail its a dually with air. On the pivot points it says "S-Works" on it but thats the only kind of identification I saw. I was just curious if you guys could tell me a little about it. Thanks.

    I believe that M4, M5, etc refers to the way in which the frame material was manipulated during the manufacturing process.
    It's better to burn out than fade away...or slip out of your pedal and face plant on the side of the road!!!

    Quote from some 2003 Specialized promotion literature:

    "M4 Manipulated Alloy frames. M4 is a unique aluminum alloy with great characteristics for making a bike:

    Strong - 24% more than 6061 aluminum (ultimate tensile strength)

    Light - excellent elongation (formability) characteristics allow tubes to be formed with thicker sections in higher stressed areas and thinner walls where stresses are less

    Durable - exceptional fatigue strength means M4 will hold up to years of hard riding"

    I found out elsewhere that it was a Columbus tubing product custom-made for specialized based on their Starship Series tubing. In a quote from totalbike.com, they had this to say about it:
    "It contains silicon and magnesium as main components apart from aluminum, and there are also little percentages of Cu, Mn and Zn. All this means a 6000 series alloy that is very resistant to high temperatures the way few millimeters far from the welds the tube reaches its highest mechanical alloys."

    The full article is here:

    Hope this helps.

    Mine is "A1 Enhanced Aluminum," whatever that means.

    If it says S-works it was a top of the line frame in its time so that's cool.
