i replaced mine, it was making the outside cable flat & worn. didn't seem to affect the inside cable. just to much
friction on that outside cable because it was much farther out more preasure on it , there is friction on the cable slide also but way less than the trg, i think you will better off if you change also, call customer service they will send you all you need to get it done. my riser was one of the earlyer ones so i made my own sts bracket, works great.
