Yep, I swap the 140mm forks to and fro from my Yelli. Geo ( HA, CS, WB ) is very similar which was the whole idea. The only negative is the BB height, 15" which takes some getting used to especially on the slow tecky stuff. Having the Talas helps though so dropping travel to 110mm makes life easier. Beauty about old Cannondale frames is they can take a tapered fork. This is a 2007 frame, so I got it cheap and no big loss if it wouldn't work. However it is riding very well and although it won't replace the Yelli, it compliments it nicely.
