I have had my trek 1000sl road bike for about a year now but only seriously picked up riding this summer and have learned I want to change a few things on my bike. My first question deals with my rear brake. The question is how do I adjust the rear brake so it isn't so tight on my wheel, I always have to ride with my back brakes open and its not very effective when I brake. So how do I just open the brake up a little bit off the wheel? My second question is how do I make adjustments to my front deraileur? When I'm in the middle ring, of my three rings up front, it always sounds like its rubbing against the deraileur and just makes a nasty sound I don't like so I usually have to skip the middle ring. Any tips?
