so how tight are you getting those bolts?

I usually try putting some material between the two, say plastic cut from a yogurt carton, which is
thin, to see if it aids friction. Sometimes it works.

This just happenened w/me in a stage race this weekend. With much tightening got the bars to stay
put - thought I was about to strip it though. But the course was very bumpy & they loosened up
from the vibrations by mile 5. Kind of felt like a front-suspension road bike so I went to the
drops. By the end they were hanging down, bolts got shaken loose. Turns out one bolt had stripped
out the threads.

This was first time I used these (Deda TT on Deda bars, two bolts on the clamp) but two things
I thought:
* Maybe I didn't have equal tension in the two bolts & it seems that would set it up to loosen up
* If I toss the original bolts & replace them with extra-long ones (that pass through), then add a
backside nut w/nylon insert, it should prevent them from loosening up. Maybe. At least it would
let me just tap the stripped threads w/out going to a larger diameter bolt.

Seems adding a rough surface would help too b/c it would reduce the tension needed to keep
it in place.

Comments?...anyone try something like this?
