I don't have one of the premium tools, but here are two other options that still work very well. Sure, they will take you a couple of minutes more, but these tools are still effective, and vastly cheaper:

Did you see the tool is only $40 on Amazon. I just watched the TriRig video, and this is the first time I've ever seen one of those tools. But it's pretty sweet IMO. I wonder what the resale value would be on eBay if you only used it once?

I can't see anything going wrong with following such advice from a company with a recent product recall.

I did it along with the cable routing through the top tube.



After drilling the holes I found out that all 3 of the rivnut tools we had at work were broken... so I bought the amazon one and was quite happy with it. I'd just buy it.

Thanks for the link to the $40 tool. I guess I searched for the one in the picture and not the one from the video. I saw prices more like $90.

Thanks for the pic! Nice job!

Nice try. 1/10 on the Troll-O-Meter.

Reviving this thread, can you please give an update on how the DIY top tube bosses are going? Still looking strong? I imagine a lightweight bento box doesn't nearly put the strain on the bosses as a heavy drink bottle being shoved in and yanked out much more often.

Does anyone else out there have any horror stories to tell about this. I'm going to modify an old frame for Di2 and thought while I was drilling might go the extra mile and install some of these.

Cheers
