All you need is a bar with about 30+ degree sweep and 2" rise. What you have is what I call a broom handle. ZERO flexibility for hands or posture.
Forget the fit. One girl blogger got 4 fits to see what happens. They were ALL different. LOL
My custom has a 610 mm TT and old style chrome bars with 70d sweep and 2 1/2 rise. ZERO back pains. Yesterday I rode my 78 lb tour bike 107 miles with my SA RD5w. Only thing sore was my bum. LOL
