Uggh! Stripped stem. What to do?(5 posts)

Uggh! Stripped stem. What to do?Mariowannabe

I was adjusting my handle bars, and when tightening the bolts on the stem that hold the bars, I stipped one. Not the bolt, but the female side. I was torquing them to too high of a spec. Its an ITM aluminum stem. Is it toast? Or, can I run a tap in it of one size larger and still have confidence that its safe?
it's toast, replace it. nmclimbo

Compare the cost of a stem to the cost of a stem failure.dzrider

I'm no alarmist but it's a cheap enough part that I wouldn't want to risk having one break. Things usually fail when the stress on them is increased. The thought of handle bars falling away in a panic stop or while rocking the bike accelerating is pretty frightening.

Depending on how badly stripped the threads are, a good LBS or machinist may be able to insert a helicoil. Properly done, it should be as strong or could even be better than the original tapped threads. Also check on price for the job as compared to a new stem.

Ditto this. Expect to pay ~$7-8 per hole.
