    80mm fork for Rush?

    A whimsical ideal hit me and I wonder if it works or not:

    Can I install a 80mm fork on a Rush frame?

    Seeing a 80mm fork works on a Caffeine and F series frame, my assumption is yes but not sure. Anyone?

    Has anyone tried this?
    I may be putting the headshok that was on my warranteed Jekyll on a new Rush.
    This ought to work well, except for lower bb concerns, because the Jekyll was great with 135/80!

    Couple of members here (MTBR) did this. Seem to me that I remember a very nice orange Rush with matching orange headshok as well. Just flip through the pages within the "Rush" section of the ""Post Pics Of Your Cannondale Rush threads."
    Here's one:

    The 80mm Headshocks have the same A-C height...I think. So, it would not alter the BB.

    A regular 80mm fork, well....

    No problem in switching with a lefty 110

    I have a Propeth SL with a lefty DLR 2 110 mm. Last year the Lefty had to be repaired just before I left on vacation, all my LBS could do was swap if for a 80mm Headshock.

    This dit not alter the geometry of the bike, riding was just the same, just less travel at the front.

    When you look at the Cannondale F-series and Taurines, you'll see them with Lefty 110 and headshock, both with the same geometry (check the Cannondale data on geometry). So from that perspective there is no reason why you could not use a headshock.

    On the picture you can somewhat compare it to my GF's Rush.

    I think that you can insert spacers into the lefty to make it 80mm.

    Does anyone have the bb height of a Rush with a headshok?

    It was mentioned that the a-c height is the same as the lefty, if thats so then bb height is the same too?

    I'm used to an 11.5" bb on a large Optimo hardtail, I wonder how low the bb can dive under compression?

    Or, how "bad" can the Rush bb height be?

    i have a lefty with spacers (80mm) for my F5 so yes you can reduce the travel on the lefty
