I've been hesitant to join the fray because I'd really like this
entire thread to wind down.  We all come to this forum because we
appreciate the form and function of lugged steel bikes that are built
with recreational / utility riders in mind.  I personally do not enjoy
the conflict that seems so pervasive in other on-line communities, and
it saddens me to see it here.

But a few things are gnawing at me.  I'll preface this by saying that
Grant is not only entitled to his opinion, but each member of this
community obviously agrees with and celebrates many (if not most or
all) of Grant's views.  However, I don't think that we should be
dogmatic.  Critical thinking is a good thing, and not only when
questioning conventional wisdom that leads folks to buy racing bikes
that are uncomfortable for recreational riding and unsuitable for day-
to-day tasks.  Here's are my personal heresies:  First, I don't agree
that carbon is an inherently dangerous or inferior to steel.  Second,
I don't agree that the weight savings associated with MCRBs are
irrelevant for recreational riding.

For what it's worth I recall seeing a number of spectacular failures
from the early days of carbon (esp. forks) in the late 80s / early
90s.  Memories of those failures kept me off of carbon for a long
time.  And to be fair, the mode of failure for carbon can be quick and
dramatic.  However, the rate of "just riding along" failures is
extremely low.  Pebbles kicked up while riding do not cause stress
risers that lead to catastrophic failure, period.  That is just
patently false.  Stress risers are caused by serious crashes (inspect,
inspect, inspect after a crash, regardless of what you are riding), or
by seriously improper installation (it's wise to use a torque wrench
when installing parts on any bike, but it's especially important with
carbon  . . . and if you wrench something until it literally crunches,
you ought to realize that you've broken it).

If you do a non-partisan review of the www.bustedcarbon.com site,
you'll notice that many if not most of the broken bikes are attributed
either to very serious crashes (e.g., tangling with a car) or non-
riding incidents (e.g., roof rack vs. garage door, spouse backing over
bike on floor of garage, etc.).  Steel, aluminum and titanium frames
do not generally fare any better under these circumstances.  I have
seen steel head tubes detached from front triangles.  I have also seen
steel fork blades detached from lugged steel crowns.  A car /
boulder / cast iron bollard can mangle any bike beyond recognition --
as well as your body.  That doesn't mean that the materials are
unsafe; it means that cycling itself can be dangerous.  And even if
the bike survives, when a cast iron bollard sends you over the bars
head first, there's a risk that you will end up with a spinal cord
injury.  I'm not an accident investigator, and I don't know the
individuals involved, but I think it's possible that this unfortunate
bike shop owner that Grant mentioned might have been seriously injured
on any bike.

I think that using the photo at the beginning of this thread to
demonstrate the inherent vulnerability of carbon is unfair.  First,
I'd submit that it's pretty rare for squirrels to jump into moving
wheels.  Second, take a look at the wheel -- it's one of those
Bontrager models with a proprietary spoking pattern that leaves huge
voids between pairs of spokes.  Third, even with those huge voids, the
wheel must have been rotating pretty slowly in order for the squirrel
to make it half-way through in the time that it took to do less than a
single full rotation.  So, suicidal squirrel plus very unusual wheel
design at rotational speed low enough for squirrel to pass through the
wheel equals crash.  As someone pointed out, this would have caused a
crash even with a steel fork (perhaps damaging it beyond rideability),
but if there's any design flaw to blame here, it's the wheel not the
fork.  Were it not for that very unusual wheel design, I think the
squirrel probably would have bounced off of the moving spokes.

Some thoughts about weight.  It does matter.  Especially for
recreational riders who ride at relatively lower speeds on hilly
terrain and do not produce gobs of power.  This isn't subjective, and
it isn't about being a racer (I am not, never have been, and don't
aspire to be).  It's simple physics.  The less you and your bike
weigh, the easier it is to pedal up hills.  If you'd like to translate
that into statistics, check out the Analytical Cycling site
http://www.analyticcycling.com/ForcesLessWeight_Page.html.  If you're
turned off by the fact that the site is populated by a bunch of Type A
wanna-be (or actual) racers, then look into the whole lightweight
backpacking movement.  The pioneers of that movement are not cardio-
monsters, they're Appalachian Trail through-hikers like Emma "Grandma"
Gatewood.  Smell-the-roses type people who have much more in common
with Grant Petersen at Rivendell than Gerard Vroomen at Cervelo.  All
things being equal, you can go cover more ground in a shorter span of
time with less weight, particularly if you're not a paragon of
physical fitness.

But it's not all about being faster.  My Hilsen weighs about 30lbs,
fully-dressed.  My MCRB weighs about half that with the small kit that
I carry.  Would you rather hike up Half Dome with a 30 pounds of gear
or 15 pounds of gear?  I guess it depends on what you plan to do at
the top of Half Dome.  On a day with good weather when you're just
going to turn around and go back to camp in time for dinner, it's a no
brainer.  It's also a no brainer to reach the opposite conclusion if
I'm planning to have an elaborate picnic and possibly stay the night.
For me I ride my Hilsen when it makes sense to ride my Hilsen, and my
MCRB when it makes sense to ride my MCRB.  I love them both for
different reasons.
