In 06 I had A Trek DX 7.5 with Flat bars super bike and did over 2000 mile tour with 4 panniers, now I have a 2012 Specialized Tricross Sport with drop bars, I have done over approx 1000 miles so far and a small tour with 4 panniers I was contemplating in changing the drops to flats, simply because I have never been down on the drops, Change or no Change
