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.
