    How do Cannondale shift bosses tighten?

    I've got an old CAAD3 that I'm converting from a converted fixed gear to a geared TT bike. At some point I took off the Cannondale shift bosses (the CAAD3 has a setup that's threaded through the frame instead of the bosses being welded directly in place). Anyone have much experience with these? I'm having trouble getting the bosses back on tightly.

    Forget it. The boss is tightened down by mounting the cable stops. You'll have to either put the cable stops back on (and remove the barrel adjusters) or find something else to replace them with-- maybe something at thethirdhand.com?
    Despite the fact that I constantly recommend Kool-Stop brake pads-- no, I don't work for Kool-Stop. (Although their factory is just a few blocks from my house!)

    I ride drop bars off-road. (The excellent On-One "Midge.")

    inside the left boss there should be a allen head or a flat head screw that you can ust to tighten up but you do have to actually have a produt like jb weld to "glue" them to the frame. C-dale still sells new shifter boss kits that your nearest c-dale dealer shouldbe able to get fore you.

    Actually, it proved to be a lot easier than any of that. I took a good hard look at it last night and found that I could remove a plastic cap that fit snugly over the drive side boss. The plastic piece fit into four nubs on the base of the boss and serves to hold the boss itself in place after it's tightened down. Hard to explain, but the end result is that it's tight this morning. Thanks for the replies, but it's not held on by the cable stops and no jb weld is involved.
