If you guys listen closely, you can hear a flutter sound from my brakes. I bought this bike 4 days ago, brand new from my local bike shops. And I thought the sound was normal, apparently not? It happens with both my front and back brakes, I was wondering if anyone knew what the sound was and how to fix it.

I did have someone suggest that maybe it was like a new abs this where the brakes flutter so that they don't lock, but idk if that's true or not.

Would love to hear your guys thoughts.

I've bought two knives from them previously, and both of them came. I live in Australia and both came at around 1-2 weeks shipping. Their quality on the b+ clones are almost 1:1 of the real thing. They also sound beautiful, crispy. 100% check them out, bbksbalisong.com
