    metal tape to protect frame under/near the BB?

    I just did a build for my kid, the carbon frame has (had) a small metal 'guard' stuck with adhesive on the underside of the chainstay up near the bb, apparently to protect from chain suck after chain drop. One the first ride with that bike yesterday on a front downshift the chain did drop and contact the frame, - the factory protective metal piece did protect the frame completely (not even a scratch), but the little metal piece came off and is a bit bent up.

    Anybody use an aftermarket metal tape (like muffler tape?) to cut their own frame chain-suck protectors? Any recommendations for tape? I'm thinking if I had a roll it wouldn't be bad to put a little protector patch on all my carbon bikes.

    Those metal guards, though thin, are still usually a lot thicker and stiffer than any metal tape I know of. Perhaps you can flatten it out and stick it on with some grey 3M permanent outdoor double adhesive foam tape...or fabricate a new one from a piece of sheet metal.
    Do the math.

    metal tape is way to thin to protect the frame. Try to reuse the stock piece or use some 3m 6mm heli tape.
    Making shit harder than it needs to be isn't awesome, it's just...harder.

    My friend has given me some of that /\ sort of tape for chainstay chain slap, and it works great, - it just might be tough enough for chain suck too. I'll work on my kid to be more gentle with the drivetrain: "if you don't talk to your child about chain suck, who will??"

    You can use casting kit. Repair tape from Lowes/Homedepot or order casting kit off of Amazon/ebay.

    The kit comes with some compression vinyl wraps. They are too short for this. Grab an old inner tube and cut it into strips and use those strips for your compression wrap.

    I just use spray contact cement on the frame and back of fiberglass to hold in place.

    I remember passing by a display of that Fiber Fix stuff at Lowe's showing a pic using it to fix a broken bicycle frame and thinking Wow.
    Do the math.

    Yeppers. On back of box ix picture of it holding bike frame together.. More of the WTF to me than a Wow though.

    On amazon you can just order/search casting kit and they come in lots of different widths and colors. You just need to supply the cut up tube. The vinyl wrap that comes in the Fiber Fix kit is no where near long enough to wrap a down tube or chainstay. But it does work for the small chainring/chain suck shield. Just tape the frame first with painters tape before putting on the fiberglass kit.

    Make the fiberglass 2 to 3 layers thick. I use 2 layers on stays and downtubes. 3 on chainring/chain suck shield area.
