I am a beginner cyclist riding an inexpensive mountain bike. I get a squeak that seems to be coming from the front tire area but only starts 2-3 miles into my ride. The squeak continues even when I'm not pedaling. I've cleaned and regreased the bearings in the front and where the pedals are. Can anyone offer some suggestions on what I can try to alleviate it and also why it doesn't start until a few miles in. Thanks for your thoughts.
