Hey guys while I'm waiting on my motor to come in I've been browsing on the forum and I see how there are a good many complaints about aluminum frame bikes. I'm using a Schwinn Frontier that I've had for about 8 or 9 years does anyone know how I can tell what my frame is made out of? I've been searching for the specs but haven't had much luck. Any help is appreciated.
Thanks,
Mitch
 
Aluminum frames have thicker dropouts than steel. The width of the welds is much wider on aluminum frames. Steel feels colder to the touch than aluminum. The magnet is the best way to tell.
