spoke tension

Could someone recommend the proper spoke tension for a rear wheel built
with a Velocity Aerohead OC rim?

TIA,

mark

JB says tension as high as the rim will bear without taking a "taco" or
"potato chip" shape; however, jb says tension only as high as the
manufacturer's recommendation, or the rim will crack around the spoke hole.

100 kgf for the right side. If true, round, dished..the left side
tension will take care of itself.

Thank you.

100 kgf for the right side.

Which is pretty much the standard number used for the drive side of the
rear wheel and both sides of the front wheel for just about any wheel
with a normal number of spokes (32-36). Except for Mavic who recommend
95 kgf, according to previously published information.

That's not really what Jobst says. It's what jim beam says Jobst says,
which are usually two (often very) different things. I guess you didn't
read the book, either.

Well, I actually have read "The Bicycle Wheel" (but not recently). So
much for assumptions.

Do you deny that Jobst Brandt has stated that ONE of the methods for
determining maximum tension is that if the rim does NOT stay true when
stress relieving [1], the spokes are too tight?

[1] Not what happens according to jb.

My (third printing, 1985) copy of The Bicycle wheel says:

"When maximum tension is reached the wheel will not remain true after
stress relieving. This tension should be approached carefully to avoid
rim damage. When the wheel begins to deform upon stress relieving, all
spokes should be loosened half a turn and the wheel re-trued."

"as high as the rim can bear" is what jobst says on this group.

"spokes must be as tight as the rim permits" is what he says in "the
book". [3rd edition.]

either way, he equates increasing spoke tension with increasing wheel
strength: "a wheel with spoke tension near the limit of rim strength can
support large loads easily" - which is untrue, misleading and reveals
gross misunderstanding.

I think such statements need a bit of evidence to be credible.

A wire spoked bicycle wheel can carry loads up to the point where its
spokes become slack from compression as they pass the load point on
the road. The looser the spokes the more easily this occurs and
conversely the tighter the spoke the less this occurs.

I have ridden many 100k miles with wheels tensioned as described
without needing to re-true them or to replace cracked rims. These
have been socketed tubular rims (Fiamme, Super Champion, and Mavic)
and Super Champion "Gentleman" and Mavic MA-2 clincher rims. I still
ride the latter as do most of my fellow riders, ones who do not see
themselves as professional like racers..

When riding rough roads such as described in rec.bicycles.rides "Last
chance road", I and my bikie friends wonder if the light weight "with
it" crowd ever experience roads that are demanding on 36-spoke wheels.

Dings in rims also come from insufficient inflation, a parallel to
insufficient spoke tension in supporting loads.
