Exceed Ultegra FD Capacity? What problems will I encounter?

I've another post on changing gearing. A couple of responders suggested a smaller (24 or 26 tooth) granny gear on the crank (currently 50/39/30). Shimano lists the 6703 capacity as 22 teeth. A 26 small ring would be 24 teeth - is that a problem? Can it be finessed?

No, it's not a problem and I've done it on numerous cranks from 7 to 10-speed and both Shimano and Campy. The shifting from the granny to the middle ring will probably be less crisp than before but the difference is minor. I do recommend a chain watcher as a precaution against spilling the chain to the inside on a fast shift to the granny.

+1, and just a note: it might take a l'ilmore finessing/tuning during initial set-up to get it "right", but you'll get there.
