Road paint and rolling resistance?

[damyth]

Generally speaking, in dry weather, would the paint stripe (say the
paint line demarcating the bike lane from road traffic) provide lower
rolling resistance than plain asphalt?

Paint stripes are as slippery in the wet (generally more so than
asphalt), I'm just wondering if this implies lower rolling resistance
as well for drier conditions.

Or stated another way, would an individual's total time in a time
trial be reduced if he rode almost all the time on the painted line
rather than the asphalt?

Yes. The more consistent surface results in less vibration and that means
less loss of energy. At least that is what I've read and perceived myself,
and it makes sense.

The effect would be small, I think. A thick layer of paint, or in some
cases it is actually a type of 3M tape heat-bonded to the road, fills in
the voids between the aggregate grains in the asphalt and will make for
a smoother surface.

I've wondered if the sharp transition from paint to no-paint on dashed
lines creates more resistance tnan the smooth paint saves. In other
words, is it worth trying to ride on dashed lines (say 2m paint, 1m no
paint, 2m paint, etc), or just solid ones?

You must have to much time if you wondering about this. Just go ride and
have fun...

Wondering about these things while riding IS fun!

Yes.

Different question. If you are preoccupied with staying on the 6-inch
line you may ride slower than you would while not thinking about it.

A serious (close?) observation.

You have posed quite a few questions about a scad of technical points,
mechanical, physiological, other. I think you have the same disease I
suspect Thomas Voeckler has - he thinks too much about the peripheral
elements of a race, loses concentration on the task at hand, cogitates about
how to do things differently, and slides fast to the back.

You have had too many picaune observations about minutiae that you pay
attention to while you are trying to race or train. I think you are not
getting to the level where endorphin energizes you. Embrace those moments.
Leave the pilot-light cerebral functions focused on the riding while riding.
If you later can extract some facts from memory, or from measurement
equipment, see if you can think about it later, not while riding.

I write this pretty candidly, so you can get a very different point of
view - not from tech wizards, but from a guy who used to do OK racing. If
you are too conscious of every element, the harmony you seek get broken up.
Try to be satisfied with what you have accomplished. Plain satisfied for
just a little time. Tell yourself you did well - without any
qualifications. Building on the good is more important, in the long-run,
than trying to correct every little bad detail.

I can't believe _you_ asked that.

When I was in grammar school, we noticed that riding a road stripe is
pretty attainable even for an 8 year old. I got my stainless elbow
upgrade by extrapolating to a steel beam at a construction site. That's
harder, as it's sorta 'pass-fail'.

I read this last night and slept on it. Some very astute observations
here which I am glad you took the time and care to share. I think you
may be very correct. At times this pointless pondering is just an
amusement, but perhaps more often than not it is a vehicle for
excuses. Particularly when I am trying to accomplish something. And I
do seldom get the endorphin action going. In a TT instead of getting
goose bumps from hammering at full throttle I'm sitting there
calculating splits based on when I meet riders who are on the return
leg and making mental downward adjustments to my goals for
"unsuitable" conditions (there are hills, I don't have a TT bike, I
didn't warm up, etc, etc). In otherwords using my brain at 100% for
nothing. At the finish I'm winded, but everyone else seems wasted. I'm
doing something wrong.

Watching the prolouge, I was hoping someone would ask one of the
riders what they think about while riding. But that desire to know
what they are thinking is indicative of my whole preoccupation, right?

Maybe I should just go for a ride. ;-)

What am I missing? Am I so crazy I have no idea how crazy I am?

Yes - in fact, I follow them myself in time trials, where they're
available and don't pass over every storm drain.
