Any recent news on AVA PIVO stems

Getting a PR-10 ready for its stem and have a very good condition PIVO stem but have heard that they are like AVA stems and can fail - Is this true - It looks in good shape - Should I not use it???

I have never heard of an issue with Pivo but I have heard of people confusing Pivo with AVA.

when a similar query was posted on the Classic Rendevous listserver asking whether anyone themselves ever has a "death stem" fail on them, there was no one with direct experience as I recall, or maybe just one. People told of other brand stems failing and many people ride with Pivo stems to this day. Bottom line is to inspect old alloy stems regularly for crack formation/spreading, just like you should with old alloy crankarms.

I think what it comes down to is that AVA didn't mark a min insert. Running a stem too far extended is a hazard on any brand.
That being said, I have seen a few cracked ava stems, and some that look worthy of racing.
Don't listen to the masses, check for yourself and be informed.

I have had a couple of AVA stems recently. One was much lighter than the others and had the feel of a piece of dried bone or seashell. It lacked an insertion mark also. I didn't use it.

I thought the problem with the Death Stems was that they had 2 expander slits at the bottom, which allowed them to expand a little too much.

That is true of a lot of the split stems but also that the stem is 25-35 plus years old. I had one that couldn't tighten and found that someone had over tightened so far that it split the fork on the keyed section of the fork threads Inspect twice and install once
