Before 2013, the 9500ci came with the ZR4 laser shifters, which at the time was aging, older technology. In 2013, they swapped them out with a re-branded "LaserShifter Pro" unit which is much better than the ZR4s, but even now, in 2017, are considered older shifter tech. If you look in the OP photos, you'll see a small box with "LaserShifterPro" means it has the updated shifters.
