Howdo!!
Can anybody help me please.Time has come to change my chain the problem is i don't have any LBS in my area.So i decided to do it myself,so here's the spec lowdown :1 pc971 chain(9 speed),1 pg990 11-34 tooth cassette,1 FSA team issue crank,1 sram xo rear mech(short cage version),1 trek 9.8 hardtail.
The problem is that i followed SRAM's instructions about placing the chain without routing it through the front or rear mechs on both the largest front ring and the largest rear,and then pulled both ends of the chain together,then as instructed gave it 3pins of slack.My problem now is the when i'm in the granny ring and the smallest cog on rear cassette the chain rubs along the rear mechs cage thus indicating that the chain is still to long.
Then to make matters more confusing a mate of mine told me i should of placed the chain on the granny ring then threaded it through the rear mech and then around the smallest rear cassette ring and then pulled it tight to the point that the tension of the chain pulled the mech down thus giving the chain free passage without rubbing on mech cage...phew!!
please can anybody cast any light on this subject,and thank you for your time.
