Handlebar to stem torque specs?

joel roth said:

I just installed 'clip-on' aero bars to my road bike. On my first ride
this morning, I notice the handlebars began to rotate downward. I need
to tighten them to the stem.

I have a torque wrench. Is there a suggested number of ft/lbs?

This is a particulary poor application for reliance on rote torque
numbers. The bars should be tightened until they don't slip anymore.
No need to tighten them more than that.

Some handlebars are slipperier than others, and there's no way to make a
meaningful generalization of appropriate wrench torque.

Make sure that you have lubricated the clamp bolts, both the threads and
the undersides of the bolt heads.

Some combinations of clipons/main bars are problematic. Putting a small
scrap of sandpaper between the bar and clamp will sometimes solve the
problem.
