    Is the internal routing swapped/incorrect on Chinese carbon bikes?

    I've noticed nothing on the forums in any category on this so I hoped it worthy of a new thread.

    This just doesn't look right, my derailleur cable is at very tight angles, and if I turn hard left it pulls hard on the housing and might cause a shift. I checked many pictures of carbon builds and I don't seem to be the only one.

    Should it not make a smooth bend around the front and enter the far side?

    It looks like it should go around the head tube, yes.

    You are all set with the routing. My 1996 Adroit is routed the same way as are most road bikes.

    You may need longer housing if it shifts on you.

    So, how do I get it there?
    If I pull the tube out of the other side to switch (run Criss-Cross), I run the risk of not being able to get either side where it belongs. Is there a trick?

    The answer is somewhat simple:
    All internal routing is foolproof, a smooth tube all the way front to back inside.
    Derailleur housings cannot be moved/relocated inside without damage to the frame.
    Simple fix seems to be longer liner in a corkscrew pattern - problem solved.

    Plus, brakeline would have had similar issues if I did manage to swap it.

    (was also investigating in drivetrain forum since it was both frame and drivetrain related.)

    I don't get the problem, run the housing around the headtube to the same hole it's in now.

    If the derailleur shifts when you turn the bars, the housing is too short. Period.

    The trouble with common sense is it is no longer common

    Longer housing is the trick, the only option is staying on the right side. These frames have only 2" or less between hole and headtube.

    I am glad you came to this conclusion. Wrapping the housing around the head tube would have caused unnecessary friction where the cable left the housing. By keeping it on the right side, the cable leaves the housing in a straight line and will perform as designed.
