    a quick dumb question

    Im going to look at a bike circa 1984 - 1985 soon. It has friction shifters on down tube bosses. Will those bosses accept indexed shifters should i want to change to this in the future?

    I'm certainly not an expert, but I would say Yes. Indexing appeared in 87 as I recall.

    The real beauty of this play, aside from the fact it was made by my favorite team, is that it was perfectly executed. The receiver ran a perfect route; Wilson threw a touchdown pass, and the defender played his part perfectly. A thing of beauty.

    Yes; and they can also be used for cable stops if you want to go with brifters.

    Not if the bike was originally equipped with Shimano shifters. From, I think 1982 till 1985 Shimano used proprietary shifter bosses. There are no index shifters compatible with those bosses and cable stops have to be modified.

    +1 on Brian's post. If you went indexing, you'd have to alter the backing plates of the shifters to fit over the bosses.
    Been there, done that, on a 1986 Cilo with SLX, had to take a file to the backing plates, then found some made for that kind of boss and indexing.
