RD7700 or RD7800??
Hi all. If some of you who followed my previous posts, i had changed to 39t/53t chainrings and FD-6500 front derail. So i have no problem with front shiftings. The next step is to change the rear derail as it still relies on RD-5504. Yeah, it is shimano 105 for triple chainring drivetrain. It looks ugly and nothing more like Mountain Bike's rear derail(long cage). So, i have 2 choices here. First, i would go for RD7700 as i dont want any compability issues again. The mechanic suggested my RD7800 as it works on 9spd drivetrain as well. Do you guys recommend RD7800 for my 9spd DA STI???
