Shimano Dura Ace CN-7901 10-Speed Chain
Awesome chain, lightweight, nice and durable. It is very compatible with all the Shimano 10-Speed range, and also SRAM too. When I used SRAM components in the past, I ran Dura-Ace or Ultegra drive train. Dura-Ace is slightly more expensive, but a bit lighter.
This is a great, strong chain, and you will never have to worry about snapping one of these in a sprint.
