Cannondale M500 rigid forks axle-to-crown measurment?

[simonpieman]

Hello, I have a 1998 Cannondale M500 currently running on suspension forks that I wish to convert back to rigid forks. The M500 geometry was designed for rigid forks. The suspenion forks are longer and push up the front of the bike, affecting the handling.

Does anyone know the axle-to-crown measurement for the original forks or how I can find out? This will enable me to source appropriate length rigid forks.

Thank you

Around 450mm I'd guess, salsa cromoto would be a good buy.
