I want to switch my drop bars with brifters to Soma Oxford bars. Problem Is I currently have a shimano 105 group 3X10. I would prefer to use indexed bar ends or down tube shifters because I have my heart set on these leather grips. I can't seem to find anything that will work. I was thinking that the dura ace 7900 d-tubes might work but they seem to be made for a 2x10 drivetrain. Do you think that setting the front shifter to friction mode might do the trick for the triple crank?
