Yeah, SRAM has made Nigel Tufnel jokes pretty easy with its whole 11-speed thing, but that's a small price to pay for improved shifting and better gear ratios. The fanciest cassette in the world won't work right without the correct chain, though, so SRAM modified its PC-1070 chain, renamed in the PC-1170, and served it up to all the 11-speeders out there.
The PC-1170 is slightly narrower than its forebear, to comply with the smaller tolerances required by an 11-speed cassette. It also has hollow pins, which save 20g of weight without decreasing strength, and has new inner and outer finishes for improved smoothness. Of course, it also comes with SRAM's legendary PowerLink, which makes chain removal and drivetrain cleaning as easy as pie. The PC-1170 also ships with a pre-applied coating of SRAM's PowerLube, so it's ready to ride straight out of the box.
