Nice conversion!
I notice you've adjusted the limit screws on the FD so that it doesn't drop into the little ring and was wondering why. Maybe your shifters are different, but I have the older generation Sora shifters on my bike (the thumb lever ones - 3400 I think) and they work for both doubles and triples. It has a third click, but I have to adjust it out as I have a double.
Is it because the Sora RD doesn't have the capacity for a triple? If not, why not put the old RD back on - all 9 speed shimano RDs should be compatible with each other whether from a road bike or MTB (cage length aside).
