Hi can anyone help me with a odd problem with my scram force setup?

everything looks to set up right but in the 52 ring / and the 19, 21, 23, 26 rings on the back the chain will jump off the bottom jockey wheel (sram force mech). but if i turn the crank back it goes back on for few seconds then if i turn it again it the right way it happens again. I had this problem before but after a while it kind of solved it self but since i put on a new sram cassette and chain it came back.


any ideas ?Thanks guys

    Look at the link where the chain jumps, it sounds like a stiff link to me. Cured by getting out the chaintool and pushing the pin through from one side or the other or grabbing the chain either side of the stiff link and twisting it.
    I've added a signature to prove it is still possible.
  • thanks fro replying.. i thought the same thing but it never seams to be the same place in the chain every time and always on the big ring
