Kind of similar to this question (sorry for the repetition).
I have an old (beloved) specialized A1 with Shimano RSX shifters. They periodically suffer from this problem where they stop shifting. I'm getting a bit frustrated with periodically having to disassemble or flush out with solvent. So I'd like to treat myself to some brand new, preferably with internal cabling.
Does anyone know if there are shifters with internal gear cabling for 3x7? I've googled around a bit but didn't find anything.
