Craig Denman, did you mean ‘hope of speed’ rather
then 'hype of speed’?
The only thing I’d question here is the size of
the grit to use. 60 is fairly coarse but maybe not coarse
enough.
In aerodynamics, there’s laminar flow (smooth) and
turbulent flow (obviously not smooth). Laminar flow rarely
happens - in cycling or otherwise. The only time I can think
of in the world of cycling is the wing design on the human
powered gossamer condor and gossamer albatross - designed to
try to maintain laminar flow. Laminar flow creates much less
drag than turbulent flow. But, the non-intuitive thing here
is that if flow around an object (like a frame tube) is going
to go turbulent (which it will), then the sooner it does (as
it flows around the tube) the less drag it has. This is
exactly why golf balls have dimples. They fly further and
straighter than the early versions without the dimples.
grit on the bottom of his shoes too? Probably
to aid slowing the bike down to a stop since his brakes most
likely failed after the one time he used them in the ride
(the turn-around). Just kidding John.
Does this mean a roadie should trim the front
and shave only the hair on the back of on his arms and legs?
Only if it’s a coasting race. I used to win criterium, now
I excel at coasting. Come on Paul, meet you at the top of
Rio Bravo!
Confused? Good. Life gets slow without it.
Paul’s life is getting faster and faster. HA!

[NMCycling] Mari Holden trivia
I remember John Frey's first TT
record because I spent so much time looking at
the stenciled 51:57 on the back of his seat tube
-- and recall the 600-grit sandpaper on all of
the tube leading edges placed there for the hype
of speed.

John Frey once held
the national record at around 52:00 early in
his career with RGRT. I remember when it
was still above the 50:00 mark around 1987
or so, then came the "fast years" from 1988
to recent. I think Kent was the first one
to go sub-50 with his Ten-Speed Drive
Guercotti, and within a year he got that
down to 48:44 or so, when Frey did his thing
in 1990 (47:35?). On that same day, Kent
also went 47:40-something. I only recall
one other person going sub-48 on the
Moriarty course, and that was Colby Pearce
with his high-dollar Lotus and Superman
position. In recent years, it seems that
the 50:00 minute barrier has become harder
to break.
All that being
said, I think the Brits were the first
ones to make the 25-mile time trial a
famous distance that was focused on for
speed records. Our times compare closely
with theirs, but it wasn't until Boardman
came along that the 47-minute barrier was
broken. Then there was a string of them
as well.
Anyway, back to
your original question, Mari Holden's time
is pretty killer. Many top-level
(Pro/Cat-1) men can't time trial that fast
on an equitable course with the same
conditions. That time will stand for a
while.
