Rivet Gun for water bottle eyelets?
So I just got off the phone with Specialized's warranty team about this issue:
The Eyelet that the Bottom Bracket Cable guide bolt threads into has fallen INTO the frame of a Specialized Venge. I thought the frame was buggered but after talking with the folks at Specialized they told me that if I can fish out the floating piece it is the same thing as a water bottle eyelet and that it can be re-installed using a rivet gun.
So:
1. What type of rivet gun would you guys suggest? I mean I definitely dont want to be shooting a rivet straight through the carbon
2. Is there some type of standard Water bottle eyelet that should be used?

with a regular Poprivet, But
Riv Nuts are somewhat like Poprivets in that you can expand them from the outside.
Though the difference is that you use the threads in the center,
pulled up against the out side flange, of the-riv nut, to do it.
It is possible to do that, without the real riv nut tool .
in even more cramped locations, with the bolt itself and a few flat washers..
than the hub QR trick.. allows.

If so, I'd try to get Specialized to send you a new rivet that is sized for your exact application. Using the wrong rivet (or trying to re-use the one you have) sounds pretty iffy to me. You sure don't want to damage your carbon frame by using the wrong size/length rivet. Using the wrong type size rivet could also require too much compression and, as such, you could end up damaging your carbon fiber frame (imo).

I'd be very worried trying to install anything like a rivet that expands into a carbon frame of a downtube.
Find someone close that repairs carbon frames near you and have them do it.
Or as mentioned above a Warrantee may be in order but they may fight you about that.

In the Bottom Bracket Id say 1st remove the crank and BB , then you can get to both sides.
Might even put in a small Machine screw, and a nut sumarily lock-tighted in place and that would be tidy.
a regular poprivet + a backup washer, is another approach. the backup washer takes the spreading head forces.

I'd install the RivNut with some epoxy. Reduced the amount of squeezing action you need to apply to the RivNut and helps "heal" the carbon. You want clean surfaces and a bit of roughing up of the RivNut's outsides is a good idea. I have done a number of water cage bosses this way without problems or further issues. Andy.

If your not comfortable with using a pop rivit gun, save yourself the grief, and take it to an LBS. Still, determined to fix it on your own? A poster suggested using epoxy to reinstall the part. I would start here, less evasive and less chance of damaging the frame further.

My reference to using epoxy was with the RivNut. Only not as much compression as when pressed into a metal tube. Andy.
