Hi Everyone, Needing some help please with my drive train. __________________________________ Firstly What I Have: CRANKSET: Custom SRAM S-1250, 7050 alloy arms, 10-speed XC double, PF30 spindle, 175mm FRONT DERAILLEUR: SRAM X7, 10-speed, 34.9mm clamp, top pull REAR DERAILLEUR: Shimano XT Shadow Plus, 10-speed, SGS long cage SHIFT LEVERS: Shimano SLX, 10-speed, trigger CASSETTE: SRAM PG-1030, 10-speed, 11-36 CHAIN: SRAM PC 1031, 10-speed, PowerLink _______________________________________ Now My Problems: - Bad Chain Slap, with clutch on and off... - Keep dropping the chain off the big front ring, I have tuned it and had the shop tune it, even lowering the mount a touch but still after about 20km of riding the problem starts up again.. - Sometimes when standing to power up a small climb the back gears would skip up one and then back down, mainly on the smaller cassette gears... On the stand the gears shift perfectly even on the trail its perfect, just when I stand up to power up a short hill it would jump every now and then. Limit screws are set and tension on cable is great for fast and smooth shifting. - This weekend my chain kept hoping off the bottom jockey free wheel of the Rear Derailleur jamming it between the cage and the free wheel. When I took it apart nothing seemed to be wrong despite seeing it wobble and throw the chain off while on the trail and stopping to unjam it. - Lastly the chain seems to have a bad flex in it, but since the beginning. Its been measured and not worn to the point of replacing it _________________________________________________ Bike is about 3-4 months old, done about 850kms and bought it brand new so first owner. I have never been a Shimano fan, none of the derailleurs I have had worked great and also been fussy. I am thinking of replacing it with a SRAM X9 type 2, most likely a medium cage since is a 2X10 setup and perhaps a new chain However would this help solve the problems I am having or must I check somewhere else for the cause of these problems before spending the money? Thanks in advance for your help, looking forward to your feedback. Kind Regards, Tim
