I recently purchased my first spinner. It is a Proform 290-SPX, and was inexpensive, that's why I could buy it. I have read a lot of reviews about the bike, but none have had the same issue. I'm getting a constant harmonic squeal while riding with any tension on the brakes. I'm think of wiping the wheel with a light silicone spay, or something, but I would like some input from folks who may have more knowledge of spinners. Thanks for any, and all input!!
