Hey guys It seems my bike has developed a squeaking noise in the rear end of the bike and im not riding it much because of it and id like to find what is wearing before i start trying to do anything with it. So this noise a high pitch to low pitch which fluctuates depending on my speed and starts when i hit roughly 70km then until i get lower than 40 it doesn't go away and it only happens once the bike has been moving at speed for a 5 minutes probable. I have had a look at the rotor and the calliper moves about half 0.5mm roughly so it looks to have a slight bend in which wouldn't be noticeable unless i took the entire wheel off. Is there anything anyone can suggest i check? ill have a look over the bike today and say if anything changes or something comes up.
