No, that will not work. Ultegra 11 speed front shifters pull more cable than the older 10 speed ones did. A 10 speed front derailleur won't match except possibly for a Tiagra 4700. One question: does your Cannondale have shorter chainstays than your other bike? Short chainstays can make front derailleur setup more difficult
