Well, consider 5,000 spokes per side ..... can you also say "disc wheel" ?

Would that be 5000 radila spokes or in a cross pattern. What would the cross be?

5000 spokes * (4 gm/spoke) = 20 Kg

That's basically a flywheel...

it'd be nice to see him do it on a team cervelo


The UCI rules on the hour. The Cervelo doesn't have round tubes:

The Hour Record is the greatest distance achieved in one hour on a
traditional bicycle, as defined in artcles 1.3.006 to 1.3.010 and
1.3.019 of the rules, and as further defined in the following
pecifications:
€ Triangular frame composed of straight, circular section tubes with a
minimum diameter of 2.5 cm.
€ Traditional style handlebars with an overall width of 50 cm maximum
and 34 cm minimum.
€ Two wheels of equal diameter, measuring 65 to 70 cm, including tyres.
€ Tyre section of a minimum of 16 mm and a maximum of 25 mm.
€ Spoked wheels with a minimum of 16 and a maximum of 32 spokes; the
spokes may be round, flat or oval provided that none of their
cross-sections exceeds 2 mm.
€ Shallow, unelongated, non-profiled rims; shallow rims are understood
to be rims whose cross-section fits inside a 2.2 cm square.
€ Other measurements in accordance with those defined in articles
1.3.012 to 1.3.017 (see figure ³Measurements²) and 1.3.022, 1.3.024 and
1.3.025.
(1) The spokes may be round, flat or oval as long as the width of a
cross-section at any point is no broader than 2 mm in any direction.
(2) Shallow rims are understood to be rims whose cross-section fits
inside a 2.2 cm square.

Riders must wear a helmet certified according to international safety
standards, intended solely for the purposes of protecting the head,
without a visor, and without any devices or shapes added to or moulded
into the helmet with the intention of or having the effect of reducing
air resistance.
Articles 1.3.026 and 1.3.033 will be strictly applied.

Can anyone explain why spoke count has a maximum? and
why is the maximum spoke count set at 32?

Preemptive strike.

No idea why it's 32 instead of 36, but I suspect that it's in case
someone figures out how to make a flat-bladed 48-spoke wheel behave as
an inferior imitation of a disc wheel. The rules are about normalizing
the bikes in as many ways as they can think of.

"In his attempt, Sosenka was using a 3.2 kg wheel and 190 mm cranks,
with his bike weighing a total of 9.8 kg."

Ondrej Sosenka: making a travesty of UCI regulations since 2006. He has
what it takes to LIVEDRUNK.

Where the hell do you get 190mm cranks? I'd be up for a set for sure.
