The newest 1071 chain features more heavily chamfered outer plates for improved shifting and quieter running. The chrome hardened pin construction provides longer chain life.
Unlike the reusable 9 speed Powerlink connector, the 10 speed Powerlock connector is not reusuable. Pick up some extra SRAM 10 Speed Powerlocks here.
Hollow pin chains save you a little weight and the PC 1071 seems to be pretty strong so far also. I've broken an XTR hollow pin chain before but so far the SRAM is holding up. Just ordered another for a great deal to have as backup. No binding so far.
Not much to say about this chain other than it works great just like all the other SRAM chains I've had. I'm using it with a 1x10 setup with a shimano derailleur and cassette and a Hope single chainring.
