Hi to y'all out there, my definition of cleaning the whole gear set includes the rear derauiller,front derauiller, and the chain. My rear wheel is dirty lyk hell, with dirt mud and grease mixed together at the rear derauiller especially.
Will include a picture of it in next post shortly.
Strip it and give it a clean wash(degrease and relube).. or just bring to LBS, around $40 or so to get ur drivetrain cleaned and relube.
