Okay, so I got my new Playmate frame and I am trying to mount a front derailleur on it, but I don't know how to route the cable because there is no little guide under the bottom bracket to route the cable (it is a bottom pull top swing front derailleur). What should i do? Is there anywhere I can buy that guide for the cable or should I just let the cable rub on the frame (I don't really wanna do this) Lemme know what you think guys! Thanks!
