so my problem is i am having a hard time finding the "clamp" on style down tube shifters for 12 speeds that originally did not have down tube shifters. My Fuji currently has bar end shifters.
if anyone can please show me a link of a down tube shifter that allows for 12 speed shifting to purchase i'd greatly appreciate it. i have searched but nothing but the common 5,6,9,10 etc. shifter comes up.
examples of the style im referring to.
and my bike for reference.
