I'm just getting into riding and am purchasing my first bike. Why is the 2003 Trek 4900 $100 more expensive than the 2003 Raleigh M 60 and the 2003 Raleigh Tess when it has less quality derailleurs, shift lever, and crankset? What other components should I be comparing? Any ideas for another suitable beginner's bike? Thanks!
