When I tighten the screw, it slips of the hanger, any ideas why this is? It was supplied with the correct hanger, running a ultegra 6800 rear mech

    assuming nothing is bent/broken

    slips off where...

    inner edge?
    outer edge?
    lower edge?

    check if the rd is screwed on all the way - no gap between it and hanger
    check if the rd is cross-threaded into the hanger - some hangers are quite soft, makes cross threading easier

    pics?
    my bike - faster than god's and twice as shiny
  • just taken it to the LBS, the b-tension screw was slip of the hanger, the guy said its just a failing with Cannodale and its hangar, he bent the screw slightly so it sits more on the hanger.

    I guess it didn't occur to the mechanic to replace the hanger or is one now on order...along with a replacement b screw ;-)

    So when you turn the crew through 180 degrees it won't just slip off it will miss completely.

    I'd ask for a free b-screw fitted by someone who has a clue!
