replacing the seatpost of a 2009 cannondale rize 3

wesrjohnson

Hello yall, I am looking at buying a 2009 Cannondale Rize 3 and I am contemplating replacing the stock seatpost with a Crank Brothers Joplin seatpost, do ou guys know if it will fit?

I figure they must make one that will but just want to make sure that if I buy one it will fit.

Thanks
