I've not tried them on the C14 but while there are some openings in the housing for the TPMS modules, they are nowhere near large enough to let any beads in. I think some have voiced concerns that the beads hitting the TPMS module might damage it but I doubt that.
BTW, I'm NOT a fan of these. I have used them and was not impressed with their performance. I always felt that the bike was wobbly while starting out after a stop until the beads re-balanced the wheels. I've found that a properly balanced wheel using wheel weights does better for me. But clearly you like them so by all means go for it.
