IT FOLLOWS THE CABLE INTO AND THROUGH THE FRAME UNTIL IT EXITS THE FRAME NEAR THE SHIFTER. AT THAT POINT THE LINER IS LEFT IN THE FRAME WITH A PORTION OF THE LINER LEFT OUT OF THE FRAME NEAR THE SHIFTER AND AT THE BACK OF THE FRAME NEAR THE DERAILLEUR. A NEW CABLE IS THEN THREADED THROUGH THE SHIFTER THROUGHT THE LINER/FRAME. ONCE THE CABLE IS PULLED OUT OF THE FRAME/LINER NEAR THE REAR DERAILLEUR, THE LINER IS REMOVED FROM INSIDE THE FRAME AND SET ASIDE FOR FUTURE USE. JUST COMPLETE THE REST OF THE INSTALLATIO
