14/15/14 vs. straight-gauge 15

Gary- This one will get quickly shot down but as at least two people here
are eminently more qualified to address the science, but I've always
contended that the 32h wheel was stronger because the spoke count was
Base 2. Just for consideration, note how the 32h wheel has 8 pairs of
spokes on each side rather than 9 pairs. BRBR

Right and a compact frameset is stiffer...

As are integrated HS...

Peter, my compact Bianchi is stiffer!

Gary, if you want to make that sort of claim on a technical board, I
for one would like to see you back it up.

"Feels stiffer" isn't good enough as there are many aspects of how a
bike feels that don't affect stiffness at all. First you will have to
define what "stiff" means in this context: vertical rigidity of the
frame, resistance to torsion, shock absorption or what.

Your compact Bianchi may well be stiffer than another Bianchi with a
different frame design or size, as could be any other bike. I think
that Peter means is that stiffness does not follow from "compact".

You have a non compact Bianchi as well, correct? With everything the same on
each bike, except for the sloping top tube? Right??

diffusion welding is really cool though.

The examples I'm familiar with are all done at temps that make Al
soft, at pressures high enough to make it flow somewhat, and take a
long time (hours.)

Like Jobst, I'm having a hard time visioning how this could be applied
to bicycle rims, and an even harder time imagining who would be
willing to pay for such an item. The price would be extreme and I
don't see any advantage off hand.

Actually, Peter, I DID. The Bianchi it replaced was SBX and the rear
dropout cracked. I have to admit though that this compact SL frame is
obviously alu so it's apples and oranges. Still, my stiffness
impressions come from sprinting and in that regard I find it stiffer
than a TSX Pinarello that I have as well.

No surprise there...altho the Pinarello TSX is a nice ride.
