Very happy with my SRAM X9(9 speed) 11-32 with a road triple running on a hollowtech bb upfront. FD is 105 and with a bit of tuning its happy with the X9 shifter. The bike shifts great. For the price I can't see how I could improve it. Suppose if money was no object I'd go internal but I really can't fault what I have. For brakes I like hydros. I have some old 530 series Deore running new xtr pads and ice tech rotors. Stopping power is off the scale. The bike I had before I upgraded to xt calipers but I really didn't feel and difference from mid range.
