! ha ha ha- ooof... I think I broke my front teeth just looking at
that.

One just has to wonder how many riders down the road are going to be
injured by these stupid light parts.

A glance at the excesses of the "drillium" days might help answer that. I
don't know how many people were injured because some drilled-out part
failed, but I did see one guy who had drilled out his brake arches. Some
of these must have kissed the road as a result.

I get the impression that the stupid light showcase bikes don't get out all that
much. Not the ones with the 135g CF saddle/seatpost with no springs or padding
and the half roll of Benotto bar tape that a stem like this is going to get
mounted on.

Did you know Mavic GEL280 rims weighed a mere 300 grams? This was
20-30 years ago. Talk about stupid light rims. Imagine people riding
such stupid light rims. Wow.

Why do you think its unsafe just because its light weight? Campagnolo
Record/Chorus ubs have aluminum axles now. Used to have steel axles.
Are the lighter hubs more prone to failure than the older steel hubs?

Huh? Who's talking about a RIM? The picture show a stupid light stem? What
am I missing?

No. Campy Record/Chorus/and up to 2006 Centaur hubs with aluminum axles are
fine. In fact, an oversized aluminum axle is probably a good place to lose
weight. Further, if you want to see an almost exact copy of the Campy hubs,
take a look at Shimano Dura Ace 10 model 7800 rear hub. It looks very, very
similar to a Campy with its oversized aluminum axle and all.

Those worked fine. What's that got to do with anything.

Of course they'll fail sooner.

If the part is designed with the material in mind, it should be fine.
Bullseye was
making hubs with aluminum axles 20 years ago. They made the axle
bigger to
take advantage of aluminum's properties. So they had very few axle
failures.
I'm sure Campy did the same and did not simple replace a steel axle
with an
aluminum axle.

A part must be designed with consideration to the mode of failure, as
well.

The prospect of a broken axle is not as disconcerting as sudden stem/
bar clamp failure.
