cboynyc, did you already convert your bike to 22" rear / 24" front?
I'm thinking about doing the same with disc brakes and Nuvinci hub on a F700 Cannondale.
I read about people succeeding in 24" conversions, but never saw a 22" rear wheel in a FreeRadical kit.
My goal is also to lower the rack a much as possible for better handling with 2 kids on it.
