Hey guys. So a couple weeks ago, I bought a new 2014 Giant Roam 2 from my LBS.
Recently, I've been noticing some buzzing sounds coming from my front brakes and only my front brakes. The sound occurs when I'm traveling fast (from going down a hill, or just pedaling really fast) and I engage my front brake. If I'm casually riding and engage my front brakes, I don't hear the buzzing noise from my front brake.
I have the original brakes on my bike, and the full specs of the bike can be found here: 2014 Giant Roam 2
So, would any of you possibly have a clue what the issue with the front brake might be? Should I worry and rush the bike over to my LBS ASAP? I would really appreciate any input.
Note: Sorry I can't provide any specific speeds. I don't have any cycling computers to measure how fast I'm traveling on my bike. If it helps, I'm a novice biker who averages 12mph over 20 miles (very rough estimate from a map and timing my ride).
