Half radial spoking and the new Dura-Ace wheels

I am sure I will ever buy such a wheel but it is sure pretty.

Sheldon's site, http://www.sheldonbrown.com/wheelbuild.html#half-radial
says semi-tangent spokes on the right side (drive side) and radial
spokes on the left side (NDS) can make highly dished rear wheels more
durable.

Look at the 2005 Dura-Ace wheels,

http://www.cyclingnews.com/photos/20...800-carbon-hub
and it looks like radial on the right and semi-tangent on the left.

Has Shimano got it the wrong way around, or does Sheldon's page need
correction? Perhaps and engineer/wheel expert can shed some light...

Questionable. Many of us make a lot of highly dished wheels that are cross 2 or
3 on the left w/o any problem.

The spoke attachment crappola for the shimano wheels is so large that they
couldn't do a cross anything on the right with cogs there...so cross left side
and radial right side. Not impossible if the hub is really stout, which it is.

monty- I have Shimano SH7701 wheels and find them to be very durable. I just
had
my first broken spoke last Sunday with 9,375 miles on the wheels BRBR

You shouldn't be breaking spokes at all.

I have a pair of wheels that are 16 years and probably 10 times the mileage and
they don't break spokes.

Good God Peter, are you still riding 6 speed wheels on a regular basis?

Why them ain't no cracks on the Rolf wheels. Rims can only crack when
they are hard anodized. You do not have to belive me. Just Google this

reality I am far from convinced that all hard anodizing causes cracks
& that non anodized rims almost never crack, which is what Jobst has
implied for years, sometimes going so far to state that any anodizing
causes rims to crack. John

In fairness to Jobst, who seems to be off somewhere right now (or at
least off on a different thread), saying that hard anodizing causes
cracks is not the same as saying that a non-anodized rim will not crack.
It is certainly true that non-anodized rims can crack, but that takes
nothing away from his observation that anodized rims are more likely to do
so.

I'll see his 6-speed and raise:

My "Brown" is still running a Regina Oro 6 12-22 freewheel, with a 30
year old Sun Tour Cyclone Rear derailer...and brand new Veloce 10 speed
Ergo brittore (that's made-up Eyetalian for "brifteurs")
