Received an e-mail this a.m. from Excel Sports for New Products.
The 2007 SRAM 10 speed chain with Powerlock (not "Powerlink"😉 is now
available:

Interestingly, no picture of what the "Powerlock Connecting Link"
looks like seems to be available. You can buy one at Bikeman for
$14.00, whatever it is:

Here's how Lennard Zinn described it last April:
"The PowerChain has hollow pins, and, like other SRAM chains, a master
link, but in this case, the new PowerLock link is not removable.
Pippin credits an engineer in SRAM's Portugal facility for coming up
with PowerLock and says, 'the linking system is always the weakest
link, but our 9-speed PowerLink is as strong as the surrounding links.
We wanted to do the same with the connector link in our 10-speed
chain, but because of the constraints of the narrow chain, we made it
a permanent connection.'
It locks in by hand like the PowerLink, but if the rider wants to open
the chain, he must do so at a different link and then install another
PowerLock link to close it up again."

" The 1070 chain is the base model, the 1090 chain has hollow pins,
and the 1090R also has hollow outer plates."
1070 = $40
1090 = $44
1090R=$54

Well, what if I'm addicted to the good old "powerlink"?
Well, I can buy a Wipperman and get an asymmetrical connex link, which
won't work if you are dumb enough to put it on backwards or upside
sown or whatever (that WOULD be me). I can even spend close to $100
on a friggin' chain if for some bizarre reason I want a stainless one
(and trust me, I don't).
I can buy any 10 speed chain (as long as I get the width right) and
separately buy a KMC missing link @ $14.
What I have opted for, finally, is IRD, which sells both Shimano and
Campy compatible 10 speed chains @ $40 with a "Snap Link" (which looks
and works similar to the SRAM 9 speed Powerlink) with the correct
width, comes with the chain, and retails separately for $11 if you
need one.

But I'm open to any better suggestions.
