    Don't do it. You will gain nothing by removing them and risk damaging the most heavily loaded tube on the frame.

    Just put a button-head bolt (the ones that come with downtube-mounted cable guides are nice) or some heat-shrink, or something on there to avoid damaging the braze-on or yourself when you crash, and call it a day.

    Even if you remove the shift bosses from the frame it will still be a conversion. Honestly, it's not worth the trouble or risk of destroying the frame. Just leave them on there and deal with it.

    You can get cable guides that fit right on. Your frame will still have something on the tube, but at least it will be a nice, smooth bump the is chrome in color. Sure beats stressing your frame like that

    Just take the barrel adjusters off. Voil!

    any time you take a grinding wheel to a frame, your doing something wrong. Mount a bell to one of them.

    Put some gears there, then man up and get a track bike.

    If you don't like how they look, save your pennies for a real fixed gear bike. But don't castrate the frame you have.

    I'll answer the question, because an 80's Schwinn Prelude is a spectacularly unimportant bike and destroying one isn't going to make a difference in the universe.

    There is no hole under the bosses. Just tubing.

    They are brazed on, with brass. They can be unbrazed, but that will wreck the paint for several inches, and it takes more heat to unbraze them than it did to braze them in the first place. This is not good for the tubing.

    They can be ground off. A carefully wielded angle grinder or Dremel tool can be used to remove the bulk of it, but you should not kid yourself that you have the skill to do the whole job with one. Nobody has the skill to do that: the underlying tubing is no more than one mm thick, and removing any of it will substantially weaken it. There was another member of this subforum who proudly showed us pics of his angle grinding job and it looked as though the bike had been attacked by a rabid beaver. That's a frame that is going to fail sooner or later. So use the power tools for most of the work and finish the job with a hand file. I'd use an 8" double cut.

    I have no interest in a "real" fixed gear bike.

    Use the shifter bosses to mount small animal skulls from the roadkill you find out riding.

    People are finding fashionable uses for roadkill all the time these days, it is an actual trend.

    pretty much sums it up, doesn't it? so you're doing this for fashion and you're going to make a perfectly good bike doomed to rot once you've realized that this "fad" is done? awesome. thanx.

    If he's asking, he probably doesn't have the skills necessary to remove them without creating some stress risers, or a weak spot.

    80's Schwinn Preludes can be decent rides.
