About two weeks ago during our Saturday ride I noticed a rubbing sound in the front wheel that kept pace with each rotation. I first noticed it after braking at the bottom of a descent, and the noise continued from there. Last Saturday I again noticed it and that it started after braking in a descent. Since we were passing by the LBS on the ride, we stopped in to have it checked. The guy who fixed it told me that the spring in the brake lever wasn't releasing all the way and also that the brake pad(?) was rubbing on something on the wheel that itself was a little bent (I bought this bike in March and the first tune-up was just last month). He suggested that when it happens, to just "flick" the brake lever a few times until it goes away. Well, as we rode off and started heading for home, I noticed the noise was still there. Last night during my easy cruise around the neighborhood I noticed the rubbing sound again but it is louder now, and flicking the brake lever does not fix it -- sometimes it makes it quieter, and when I press the lever a tiny bit the noise stops but then starts again when I press it further or release it. At one point I made a U-turn in the middle of a street to change direction, and the noise briefly got even louder (perhaps whatever is rubbing in the wheel is affected by sharp turns?).
I'm planning to take the bike back to the shop and ask them to take another look. Maybe if they don't/can't fix it, I'll take it to the other LBS where Hubby bought his bike (the same one that quickly noticed that the cabling wasn't installed quite right on his road bike at my LBS.)
Does anyone have any idea what might be the problem?
