Water bottle rivet

Is this a straightforward repair with a rivet gun?

Check out a Rivnut.

Should be pretty straightforward.

a rivnut, a washer, and a long bolt will do the job

The hole seems large for a cage bolt sized rivnut but maybe my eyeballs are just not calibrated today

agree, looks like a di2 port from here.

If you're in the Bay area, send me a PM. If you bring your bike over, I can pop in a new rivnut.

Agreed...port for wire...too low for a bottle cage bolt.

I think others have spotted it -- a Di2 port. If a bottle cage, there would be two of them which would of course be telling.

It does look large. Rivnuts come in different outside diameters so you have to be sure to get the right size; one too small and it'll end up tearing the metal and ripping out, and then your frame is likely kaput.

Installing a rivnut can be done with a bolt with matching thread but this will be a relatively big rivet and they don't compress well without the help of the proper tool. Plus, the tool lets you crimp it evenly rather than causing it to wiggle sideways, distort the hole, or twist the tubing itself. And you have to get it tight or the rivnut just spins and ultimately rattles. I feel it's poor economy to save the $15-25 it costs to have a shop install one with the correct tool. BTW, there are at least three different rivnut tools I know that fit different rivnut sizes and work with thin tubes, burly tubes, close quarters, and so on. Be sure you have a bolt with the same 5 mm thread threaded into the rivnut; that keeps the crimping process from distorting the threads and rendering the rivnut useless.

THis!.

Definitely not a Di2 port, frame predated electro shifting. Also has the corresponding bottle cage bolt above it (sorry, edited it out of photo). It’s definitely supposed to be for bottle cage.

What diameter is the hole, what threading in the other nut above, M5, M6?
I have a rivnut tool set that came with some nuts; I can check whether there is a matching one.

Just checked:
OD for M5 is 6.9mm, M6 is 8.9mm.

Very straightforward repair with a rivnut tool. It is a little less straightforward, but you can DIY using some washers/spacers and a quick release, but as 11.4 mentioned it will wobble and be more difficult. The right tool is the better choice if its available.

Op, consider using washers to clear the clamp. IMO the cage will be touching the FD clamp.

that's not a repair

Thanks for the feedback, this is such a great forum of knowledge (and great deals!). Shared the info with owner of bike, initially thought I’d try the repair but don’t want to chance it on something that is not mine. I’ve reset a few of these but never put one in!
