I purchaced my first bike about four years ago assembled. I rode it the first summer and noticed that I had a wowy in my rear wheel. After checking I found a couple of broken spokes. Ridding season was winding down so I continued to ride on it until winter. When snow started flying, I tore the wheel down and found seven broken spokes

and the heads almost worn off of most of the spokes on the drive side. The moral of this story is to never mount metal to metal when it comes to spokes. With spring comming up I would reccomend everyone to go through everything on their bikes and making sure everything is tight and nothing is broke...Kelly
