just glued bearings into all allen holes on my bike, looks really nice (i think) as well as reassuring.
for the record - you'll be wanting 3/16" bearings for 5mm allen holes. they fit a dream, i also used one in the 6mm saddle hole. obvously a bit looser, but still a deterrant and it only a charge bucket anywayz...
what type of glue do you use? i can't imagein how one would glue metal to metal
