I am running a 9 speed 105 drivetrain with the stocker KMC chain. It is getting a bit old and am overwhelmed with all the different chain choices out there. I have not heard great things about mid-low end shimano or SRAM(under $35), but great things about Campy. I see new 9 speed Daytona and Record chains selling for $25 and $20 respectively on ebay all the time. Are these compatable with Shimano gruopos? Can I use a power link on them? Sorry if it's a total noob question.
