Comparison of Auminium, Steel and Carbon forks?

Are there any impartial tests that have been done on Auminium, Steel
and Carbon forks? Some people say carbon absorbs vibration better than
steel and Aluminium, others say it makes little difference... etc etc

The differences of design, materials quality and manufacture are greater than
the differences in the materials themselves. Even in weight there is an
intersection between the three. I've got bikes with all three and they've all
got something going for them.

Really depends on what you're doing with the bike and which forks you're
choosing from.

So do Carbon forks really absorb vibration significantly better than
Aluminium, so giving a better ride?

They definitely vibrate differently. I don't know that it is less. I do know
that with stupid small tires pumped up stupid hard they are noticeably less
annoying on buzzy road surfaces. I also notice that I don't notice it that much.
The only reason I own carbon forks at all is because I found them at a
ridiculously low price while building up a bike. I'm sure if I'd spent $350 on
the damn things I'd be telling you all about how much better they are.

It does if you think it does (see: "the placebo effect").
 
Aluminum sucks for forks. Youll rattle out your teeth. Steel gives
the plushest ride but with heavier weight than carbon. Carbon absorbs
shock well . I have all three and the best thing I did on my cross
bike was swap the aluminu fork for a carbon one. My two favorite
rides are a Lemondsteel with carbon fork and a Bianchi steel/steel

How many points for a mid-thread troll?

careful now, r.b.t regulars are here to shoot the ****, not commit
heretical acts of reality checking such as you have just done.

the best "impartial" test you can do is ride them yourself and compare.
not something some people with mere opinions are prone to do.

You didn't miss the celeste part, right?

It does if you think it does (see: "the placebo effect").

Even if you don't think it does, carbon forks, in general absorb more vibration than aluminium.

Yeah, there are no impartial tests that establish the relative characteristics
of forks made from different materials. Such a test would have to hold all other
variables constant in a way that simply isn't possible.

How come? Not arguing, just curious. Seems (to me, not a mechanical
engineer nor wrench) that one could get three forks with same geometry,
tilt at proper head tube angle, clamp dropouts to shaker table, add mass
loading from above, hang some accelerometers on the stem and let 'er rip.
Just to see, y'know?

That won't tell you much about the materials though. You could do the
same test with three carbon forks with the same geometry and get
vastly different results.

what's hard to hold constant about a transducer attached to one end of a
fork, with a known vibratory input at the other end?

I assume we're not saying that quality control is so poor that three forks
of the same brand/model would not measure the same. More like small
changes in fork shapes, cross-sections, etc., have a bigger influence on
vibration transmission than the the material itself. So the chances of
finding three forks of different materials which are built sufficiently
similar that those other factors will not contribute to the results is
slim to none.

"vastly"??? ok big guy, you need to go ahead and define your
understanding of "vastly" now.

I have riden all three and I can't really say that I know the
difference. Nowadays, there are mostly carbon forks and can be had for
as little as $70.00. Since they seem to ride fine I use them. They
seem to be made a lot lighter than steel forks and they tolerate my
200 pounds w/o problem. So, I think that they are fine for what they
do. Regarding shock absoption, etc. I wouldn't be able to tell the
difference or ride quality, I wouldn't be able to tell the differece.
