OK guys, now youve got me worried!! Forgive me for being a newbie (and a girlie) but ive never heard of wheel weights before, however i do have sticky pads on my rear wheel where there obviously used to be something attached that isnt there any longer. Is this something i need to act upon or worry about?? Ive just checked and the front has 20g on but the back just has the remains of a sticky pad. Sorry for being a bit ignorant but we all have to learn somehow and this forum is rapidly becoming my oracle!!
