    I have a bike like that. I had to get a length of housing that stretches the entire length from the derailer to the shifter, then cut out a small section for the sensor. Put on first length of housing, then sensor, then the other length of housing.

    You would essentially no longer be using the original design where they do not use housing, so you might need to ziptie the cable to the frame instead of using the oddball methods they use for doing without a bit of housing (they mostly do this to save a few pennies per bike so it's fine to build it with actual cable housing the whole way)

    Great, but what if you have bare cable wire and no cable housing? Is there a workaround? Need to mod some cable housing pieces, I'd imagine.

    I had problems with my new bike with brand new gear sensor. The cable slipped over the pully wheel, result: no detection of gear shifts.

    I took the gear sensor apart, at this part, the little silicone gasket came lose. I slightly greases the pully wheel axle. And de-greased the part of the shift cable where it make contact with the pully wheel.

    After that : 100% shift detection.

    ​​​Used 2cm diameter shrink tube and some self vulcanizing tape to protect the gearsensor from dirt.

    Protecting your Gearsensor from mud and debris

    The gear sensor is easily the most useful add-on developed for BBSHD and BBS02.
    Although it is waterproof mud and debris can still get inside, especially from offroading and singletrack.This can affect the gearsensor's usability, possibly leading to needing opened up and serviced as shown here.

    To avoid this, you can take extra steps to protect the sensor ahead of time.

    in the above picture the person used heatshrink tubing of various lengths to completely protect the sensor. This is a great approach for a new install since you can put the tubing on at the same time, otherwise it involves removing the cable and housing.

    Another approach is to use self-fusing silicone tape and just wrap around the pre-existing install. In this example it is being used instead of zipties to keep it held to the chainstay. The silicone tape fuses to itself so it is essentially one piece within 48 hours. The benefit here is that you don't have to remove any parts and can just wrap it over everything that is already there. In this example xtreme tape was used but other brands will work as well.
