Opinions on Saturn Sewup Rims
* * Chas
know about these rims?
They're made in Italy and were supposedly used by the US Olympic team in
1984.

Not a great answer for your specific question, but my only clincher
front wheel is a Saturn HC-19 on a Dura-Ace hub from 1985 that is
still going strong although it, admittedly, gets little use other than
on the trainer during the winter.

The importer changed the name to 'Saturae' as the auto company's use
was prior to his use. One of the TM areas is 'transportation' so we
group with cars and Harleys and Boeing.

I found the info I was looking for in a Specialized ad in a 1984 Bicycling
Magazine.
Staurae Tubular Rims
HT-C21 22mm wide 470g
HT-S20 20mm wide 410g
HT-R19 19mm wide 340g
Staurae Clincher Rims
HC19 19mm wide 400g
At 470g the HT-C21 sort of defeats the purpose of riding tubulars except
maybe cyclo-cross.

Super tough, laced on 14gauge x 36 with a 22-23mm tub.

G'wan, say over here what you said over on urc about what to do with the
spokes, I dare you :-)

The Saturne rim is extremely stiff for its section, 20x12mm, being
about 18oz
Made up with heavy spokes as I have done makes it unnecessary/
undesirable (and hard work) to tie up the spokes as the structure is
so rigid. I didn't.
The Saturne rim will not benefit from the expense of lighter butted
spookes. If 15 gauge were available at the same minimal cost, I'd
have used them on appearance alone.
Spoke position is important, the use of fewer crossings reduces the
angle between the inner spoke and the hub flange. Tie-ing at the
second cross(away from rim) pulls the inner spoke towards the flange.
Both transfer pulling of the head to pulling on the bend, most
desirable. Tie-ing at the second cross reduces the rocking angle of
the spoke by bracing with another spoke pair, extending the life of
the spoke before fatigue failure on the bend. Greater crossings also
reduce the rocking angle by taking the first crossing further along
the spoke towards the rim as when spokes are left untied.
Applicable to all woven spokes is the correction at the first crossing
to remove the bow in the spokes by bending them here during fitting so
that they may rest in the same position with zero tension as with
excess tension.
