Is this the Zoom stem you bought?:

I have these on a couple of bikes, in the max (130mm) size, fully
extended, and I don't notice any flex. I'm also 230lb and use 46cm bars.
I'm hard on stems, I broke a forged Nitto stem. The Zoom stems seemed
stiffer, it's hard to imagine how they could be more beefy.
Yes, indeed we are talking about the same Zoom stem.
Your comments are quite interesting in light of my personal experience.
I'm only 155 lbs and use the 110mm stem with it very conservatively
extended.
This stem has a very similiar design/profile as the stem originally on
my bike. I do notice the Zoom stem is lighter. I think that is due,
in part to a couple of observations like a shorter neck (vertical
height) and it has a hollowed out section located where the back of the
handlebars meet the stem.
I've read some on-line reviews on the Profile H20 stem and the reviews
are mixed about its stiffness. This includes a 2001 bicycling review
and roadbikereview.com as a couple of sources.
Between the old and new stem, I've had the same fork, frame and wheel
and the same model handlebars (beefy Profile Design hammers; replaced a
couple of times due to crashes or for safekeeping).
Confusing things more a bit, between these two stems, the OEM and the
Zoom, I did have another Zoom stem on the bike, last year. Same model,
just a 100 mm. For $40 (2x20), I figure I'd experiment with my bike fit.
Long story short, I hated the fit and ride characterstics using the
shorter stem and ended up swapping out the Zoom 100 for the Zoom 110.
While I had the Zoom 100 on the bike, I did not notice it to be flexy.
Maybe I was too occupied with the poor fit to notice if it really was flexy.
Perhaps I need to loosen one of the Zoom's bolts and tighten the other
more. Yeah I know..grasping at straws...I read such advice about the
Deda or Profile stem on roadbikereivew.
Anyway, thanks for your reply.
