Bike Forums - Rubbing Noise Sound Cant find

I just bought a 2013 SL4 Tarmac Expert and I have a front sounding noise that sounds like a low pitch vibration but is not brakes, I loosened the brakes to be sure ....the noise is not continuous but begins around 3-4 miles and very hard to describe except as like a low pitch brake drag vibration or a dry bearing. I have changed out front wheel axial and wheel with no luck... :notamused: The noise continues even when you stop peddling so I would not think it is drive train related. I have noticed that noise seems less when going 19+ mph but that could be the wind noise canceling it. I will change out the back axle and wheel to see if the frame is transferring the noise to the front. Any help is greatly appreciated!
