SRAM PowerLink Gold Connector 9-speed (4 pieces) 2014
The convenient PowerLink makes it easy to join links together. No tools needed. Insert, press, lock - it's just that easy!
I actually prefer quiet, clean shifting Shimano chains, but I always use these on my Shimano chains. I also carry a few in my pack incase I break a chain on a ride or see a stranded unprepared rider. Just nice to be able to quickly remove a chain for any reason.
