hey
I am a big fan of SRAM chains - on my 9speed bike.
On the 9-speed, SRAM magic links are re-usable.
I luckily found the risk of jumping ahead with SRAM for my 10-speed chains. I went with KMC on my Ultegra-6600 gruppo and with Shimano on my Ultegra-6700 gruppo (I have 3 bikes).

SRAM kind of messed up their 10-speed chains, in that the magic link isn't really that magical. It goes on but I think they acknowledge it's not really supposed to come off, or be re-usable. Go figure.

So I never went with SRAM on 10-speed, still use them on my 9-speed, and stick with Wippermann magic links and KMC chains on my 10-speeds.

Enjoy!
