    Default Bike designed around the lefty fork- what happens when I slap a rigid fork on it?

    This weeks question-

    I have a custom 29er that is designed around the lefty that I am putting back together.

    In an effort to save some monies, as I am not necessarily in the market to buy a new lefty/wheel and a plethora of forks/wheels, I was wondering what would happen to the geometry of the bike if I decided to install a rigid suspension corrected fork (frame was designed around 100MM) or a Reba 29 fork.

    Other details- I am sure I am missing something.
    I am considering using a Chris King inset headset- not sure if I want to use a 1.5 external cup or just use 1 1/8 inset.

    Questions-
    Does my headset choice change handling?
    Will a Lefty designed frame work with a regualr fork?

    Gracias guys for any of your thoughts.

    Do some research to find the axle to crown and offset of the lefty. If either neasurement is within 10mm of a fork you can enjoy a stock fork.
    Use an external headset cup for the extra 12-15mm of stack height, cups and races are available in every conceivable combination.

    A-to-C on a Lefty is quite short. I ended up using a Reba set to 80mm and it was still about a cm too long. Never rode the bike w/ a Lefty, but handling was fine. Frame was built around a Lefty 29er.

    Gracias guys- the feedback is muy appreciated. Sincerely.

    From what I have put together using the google is the following-
    Axle to crown for Lefty 100 is 480
    Offset is 45

    For the Reebster the google tells me the following-
    Axle to crown for reba 100 is 509
    Offset is 46

    For 80 it is 489.

    Is that too big a difference?

    So if I have a Chris King 1.5 already in place0 I will need the conversion to use 1 1/8 forks.
