    DUC32/Seven Duo Help!!!!!

    Hi all,
    I recently came into a seven duo frame that I was going to build up. Additoanlly, I have a DUC32 that I was going to put on it; however, the duo has a long 7 in.(178mm) head tube. I was wondering if you guys knew of any crowns, or anyway I could get this to work. I know there are tall crowns, but from what I can gather the max height they can accommodate is 172mm. Any help would be greatly appreciated.

    Thats a hard situation, the only thing I can think of besides a custom upper crown is trying to figure out your stack height using a zero stack headset top and bottom. This can only work if you have at least a 41.4mm inside diameter headtube.

    On edit you may only be able to accommodate a zero stack set up with a 44mm inside dia. headtube.
