    Cannondale C2, C3, & C4 Stems

    Could someone please enlighten me as to the differences between these three stems?

    alright I'll give it a shot... a 100mm C2 stem weighs about 125g figure a C3 stem would weigh about 150g or so and a C4 even more.

    Think interms of shimano groupsets

    dura ace - C2

    ultegra - C3

    105 - C4

    these are generalizations as I have only weighed a C2 stem but you get the idea right?

    thanks for the reply. For anyone else interested the difference - C2 & C3 look identical but the C2 is made from 7075 instead of 6061 aluminum on the C3. The C2 is slightly lighter. C4 is 6061 with heavier faceplate

    Not sure of the newer ones, but I believe Cannondale used to have Syntace make them. Typically the Syntace road stems are very light and strong...

    those numbers seem very lite for C4 ... not sure why cannondale would even bother with C3 and C2 if thats right.
