why so much stem failure?buffalosorrow

Time and time I hear, read and have myself stem failure. Why has this not been corrected?

My ITM open stem threads are striped, its a $25-30 stem I barely rode it. Im looking for a solid stem, is my only option the Salsa S.U.L? Hell it looks good, on steel frame bikes.

Are Deda, ITM etc.. going fourth with repairing or
re-designing their stems? I have read about the recalls.... but have not information.

The torque spec for all of the bolts on my Thompson stem workes out to be something like 9 or 10 foot/pounds. That's not very much. Left to my own instinct I probably would have doubled that.

There's also a sequence procedure for tightening the bolts. You should gradually "walk" the bolts up to the recommended torque. It takes me three or four times around to get them all up to only 10 foot/pounds.

I think that not using the proper sequence will tend to result in a loose handlebar, so guys compensate by cranking the bolts. The result isn't good.
