You don't have to expose yourself by subscribing to this rubbish. You
ought to ask guys like Ritchey, Fisher, Breeze and the like where they
got into dirt riding. It was on Sunday rides in the Santa Cruz
mountains on my weekly rides, before we ever heard of MTB's. I still
ride these roads as I said and get the gasps from incredulous riders
on squishy fat tired mounts. I guess you choose to count yourself
among them. Just like the guy on the MTB who skidded to a halt as
though he wanted to tell me something as I rode down a flight of
stairs yesterday.

So, that doesn't mean you weren't there and you didn't do it. Just
think how it would be to ride the suspension knobby tired bike 50
miles back home after that tough spot. I think seeing the big picture
is more important than optimizing a spot of dirt somewhere. There are
many people who ride on long road tours with knobby suspension bikes
"for just in case it gets slimy somewhere". I see them all the time
riding from Seattle to San Diego. They tell that they need them to
ride across fields when they find a muddy camping site.

Yes and most suspension bikes cannot be carried over the shoulder with
one hand.
You keep saying that I claim a road bike or cyclocross bike is better.
Nowhere did I say that. I merely said that you can do a lot more with
a thin and smooth tired bike than the MTB crowd believe. Why is it
that when I propose something, you try to disprove it by distorting to
the extreme? There must be a defensive mentality at work defending a
faith in something that needs defense.

As they say in politics, "there you go again", putting spin on my
riding the bike that I ride. I get passed regularly on rough rocky
descents by fat tired bikes, some of which have suspension. That does
not mean I NEED to have one to ride there, nor do I want one to ride
the road miles that lie between my house and the Santa Cruz mountains.

Trend. I'll wait and see if that holds up. I am not convinced. I
also don't know that there are any significant hills in that route, so
a generally flat route makes a sprung fork that weighs a little more
acceptable.

Well in civilized society, here in the west, there are no reasonable
100 mile muddy dirt roads that one might go riding on. The land is a
network of paved roads with some region of trails. That's true of the
whole area, including noted Marin county. Sure, I've flown across the
USA and seen hundred miles of dirt roads but that's not where I go for
a weekend ride. I go out on a 100 miler every week and some part of
that, like 20 miles or so, goes though rough terrain and trails. Most
of these trails are used by horses and hikers so they are not ankle
busting boulders. When such sections arise, I portage. The rest of
the day is pavement.

Why do I keep running into exaggerations of the extreme whenever I
mention anything. I never said I scale tall buildings at a single
bound, more powerful than a speeding locomotive, or eat bullets shot
from rifles. What's going on here? I merely said that I prefer to
use my smooth tired road bike and enjoy trails, so I get a rash of
"you can't do that" and "you're wrong", its boulders and branches and
grueling conditions. I believe there is a lot of dirt riding that can
be done with an all around bike. In similar fashion, you'll mostly
see Tom Ritchey on a road bike out in the rough. When I find smooth
tire tracks on a remote trail, they're usually his.

Who ever said everyone must do this? There you go again, generalizing
to the extreme. All I said was that I do this and find it more
convenient than burdening my ride with a full suspension knobby tired
MTB because most of the ride is not a challenge of man and machine
against nature, but rather a ride to enjoy the outdoors. My tour in
the Alps is a 2000 mile version of the same thing. It includes road,
trails, rocks, and snow.

A good cyclocross course has obstacles that require portage, some
degree of trials riding, and a road section that is uphill and
relatively fast. If you put that together, you'll find no suspension
bikes and probably no mountain bikes in the race. A fast descent over
rocks benefits the fat tire and I've seen courses where this was
purposely included to benefit the MTB's and give a good mix of
equipment.

I think you'll find that to be incorrect and puts the cart before the
horse. I seldom if ever initiate a news thread and generally am
responding to postings that spread misinformation. This thread got
started when I said I rode trails with my road bike and was told that
my trails were too smooth and that where the action is, I could not
ride without suspension. I disagreed and said why.

He still builds road frames and built me a custom frame that I rode
for nearly ten years before I wrecked it. It was the lightest bike I
ever had and rode wonderfully. It was for this bike that I designed
his logo and headbadge, because I didn't like the old "Lettra-set" T.
RITCHEY he had been using. It is on his hand made frames where his
exquisite workmanship and fillet brazed joints that need no filing can
be fully appreciated.

I think it is, because it's one of his own bikes and he uses his own
hardware if someone were to notice. I doubt that anyone recognizes
him out there, he rides trails not seen by MTB riders who don't want
to ride that far from the truck and on pavement. On the road people
don't take note of him although he rides his team jersey. You'd have
to look for his handlebar mustache.

That has some other effects. Besides a $5.00 bicycle probably not
being up to the task mechanically, the riding position of a MTB is
more stretched to avoid endo's on trail riding, that is the distance
from handlebar to seat is greater, which makes long distance pedaling
less comfortable and effective. Another is that most MTB's are
equipped almost exclusively with knobby tires that roll miserably,
especially on hard surfaces, those on which most bicycle touring take
place.
I encounter European tourists traveling along the California Pacific
coast on HWY1 with MTB's on ultra knobby tires. They make slow
progress even with the tailwind that regularly blows from the north in
summer. I coast down some of the grades sitting upright and pass them
with a significant speed margin, one that tells me their rolling
resistance is significantly greater than my road slicks. Of course we
know that from RR tests.
If you insist on using an MTB, at least get some slicks and try to fix
the position by using a short bar stem or even a short one turned
backward. Of course, I see the same thing in the Alps because young
(non-bikie) athletic people who can do these things without a lot of
training believe MTB's are made for riding in mountains. They are
not.

The Cinelli had my first "Campagnolo" vertical dropouts but was brazed
in a process that caused fatigue failures at the BB/Seat tube. Peter
Johnson built me a bicycle that had all the same dimensions and it
worked excellently except that the right chainstay was a bad tube. We
don't know what it had but it broke at mid span. A parch was brazed
on and Tom Ritchey offered to build me a new bicycle.
That was the lightest frame I owned but I ruined it about 10 years
later by descending a forest road that had a fairly short "rolling
drain" (a diagonal cross ditch that almost matched the wheel diameter.
That incident wrinkled the top and downtube but the bicycle was
ridable. In the following week, before I could arrange repairs, I
was struck broadside at an intersection across the street from my
house as a driver made a left turn into me from a stop sign. The
frame was a loss and peter Johnson built me the frame in the picture,
also the same size and with long chainstays.

I have only one bicycle, the one in the picture, that is my racing,

Too much maintenance. Besides my bicycle fulfills all the tasks well
enough. Sometimes on a rough descent I would like to snap my fingers
and have two inch cross section tires but then I don't need to go that
fast. I still get down those rough trails as fast as others with whom
I ride.
