Finally took the plunge on drilling and rivnutting. The bolt trick didn't really work for me, but I could borrow the proper tool and it seems to be solid. Has survived its first ride with some seriously bumpy parts, I'll wait it out for another week and then add another set to this bike and a set to the Unit.
Nice, I was watching a video on how to do this the other day. Thinking about adding seat tube bottle bosses to my Inbred - where did you get the insert things/rivnuts?
