| I bought an Expedition about a year ago and have most of the bugs worked out except for a persistant drivetrain problem. The chain jumps on the rear sprocket on several of the gears. This problem persists even though I put on a new SRAM chain [after the original brike 2x in less than 6 months] that's one continuous piece except for the quick link. New rear sprocket, different rear shifter. Doesn't matter which front ring I'm in but I notice it mainly on gears 3 & 4 [counting from the smallest rear ring]. It's about to drive me nuts and my LBS mechanic thinks I am crazy. Charles Rathbun ~~~~~~~~~~~~~~~~~ "It's a beautiful day out there. What are you doing inside?
