I just got a screaming deal on a brand new Deda Mag00 stem via Ebay. Why?
Is there something about this stem I should know about? Are they prone to
breaking? I am planning on using it on a secondary (in-town riding, winter
training, LSD type rides)....The stem coming on my new bike will be a 120 so
I found this one. I am just amazed that a stem that once (just a couple of
years ago) sold for well over $200 is now not worth very much at all!

Be extra careful tightening the bolts on the stem. Both the steerer
clamp and the handle bar clamp plate. The threads are in the magnesium
stem body. Magnesium can strip very, very easily.

Magnesium isn't one of those materials that most feel comfortable using in
an application where failure, as they say, isn't an option. It doesn't seem
to hold threads well, it's prone to failure if damaged... Magnesium is one
of those often-rediscovered "wonder materials" which someone in turn
re-discovers why it's not so practical after all.

Is the geometry such that you can drill it out and use nut-and-bolt
through-and-through?

It looks like you could do that with this stem. Not very elegant
looking and it would negate the weight savings. But you could keep it
in use.

Some mag stems are/were prone to failure... as in defects in the
material leading to sudden breakage. This was not a thread stripping
issue. I don't know about this one in particular... but since it is so
cheap, I'd be suspicious. Do a search and see if you can find any info.
