Can a LBS easily replace a stripped frame threaded insert?

Just asking, both my pannier frame top mounting rivets, are stripped and it looks like its just the rivet inserted into the frame hole that's stripped. can my LBS easily replace those riv nuts?

That’ll depend on the LBS. They may be able to retap or they may need to braze in a new insert. The second option will definitely damage the paint.

Any chance you could give less information?

Frame material?
And it sounds like you have existing riv stripped nuts that you want removed and replaced? Depends upon frame material (I'm guessing AL or CF, right?) and if the rivnut is spinning in the frame, or if its just the screw spinning in the fixed rivnut.

With care, rivnuts can be removed. So it depencs upon how skilled your lbs is.

Rivnuts can be drilled out and replaced, provided that they are still secure and not spinning. The chances are almost 100% that the back side of the rivnut will fall into the frame tube and rattle around in there for the life of the frame.

Are the threads stripped or is the nut spinning in the tube?

This is a very important distinction. If the nut is spinning in the frame, the fix is rather easy. If the threads in the nut are stripped, that's a lot harder to repair.

Because it's impossible to remove a fork or a bottom bracket, right?

Nope. If its in the seat stay, there is not likely to be a vent hole large enough to get the piece out of the frame.

If the nut is spinning then you just need to snug up the nut in the frame. Here is one of many videos explaining how to do it with no special tools. Make sure not to use too much force. Only enough to stop the nut from spinning is necessary.

If it's spinning but the threads are still intact, there is a chance it can be tightened into the tube wall. I have done this a number of times. Sometimes, wedging something thin like a feeler gauge between the flange of the riv nut and the tube will hold it in place enough to thread the riv nut tool into it and then a good squeeze will lock it in place.
In the absence of the tool, it can also be done with a bolt a nut and a washer.

It all depends on what the actual problem is and whether your LBS has the skills and tools to repair it. A decent LBS should have a riv-nut tool and new riv-nuts to replace damaged ones. Chances are if your LBS has been in business for more than 10 years they should easily be able to handle it.

Personally my first fix attempt would be to tap it out to the next size and use the next size fastener. That is if it looks like there is enough meat there to do that. Usually it's not like you're threading stuff in & out all the time, and once something is installed it's there for a while.

I wouldn't expect every LBS to be able to do all the same things. So you really need to ask them. Some may not even attempt to do anything, some may have more expensive solutions and others might have less expensive solutions.

The shop I work at could do it and I know plenty of mechanics who can do it but you would need to ask in your case. Head down to the local shop and see what they can do. You might also ask local frame builders and see if they can help out if no shops around. However without knowing much about the bike and what is going on it is hard to help beyond that.
