I had my bikes for few months now, and from the first time I picked it up from the tune up and assembly my breaks felt funny, they weren't tight enough and stopping power was bad. So I took it to adjust them, which they did by putting break pads very close to the rim, I never seen it being that close on any other bike. On one of my recent rides I had a hard time stopping at a red light and that got me really mad, so I took it to the shop again where they tightened break cables , which really helped. So yesterday, on my ride everything seemed fine until I started hearing a rubbing noise. I stopped and checked my wheels, and the rear one was rubbing on the pads. My bf adjusted the pad so they don't rub but we still decided to take it to the shope.Took it to the shop again where all he did just put the pads back close to the rim, I checked the tire and it didnt rub. Came home and it ......rubs again. I am so frustrated, the guy at the shop told me that if I want good breaking it has to be close to the rim. I personally don't believe that. Did any of you have same problem or know what should be done? Please need advice
