    RM Vertex 70 BB Size & Seatpost Size?


    After along time away (my Blizzard got nicked in 2001) I'm back in the RM owners club.
    Got myself a 2004 Vertex 70 frame and am now trying to sort out the build.
    I measured the BB width and it seems to be about 70-71mm (inaccuracy in my measuring not the frame) so is it a nominal 73mm shell or 68mm?

    Whats the seatpost size?

    The BB shell should be 73mm and the Vertex seat post has been 26.8mm for the longest time, although they may have changed it to 27.2mm when they changed the ETSX frames to 27.2mm for the 2005 model year.
