Hey, I'm making a decision inbetween 2 bikes at the moment. I'm deciding if I should get either a Trek 4300 mountain bike or a Hardrock pro Specialized mountain bike. I test road the Trek and I test road the Specialized, but it was only around a FLAT square of a parking lot. But I test road the Trek down a semi hilly street. So I really can't compare... um, does anybody have any opinions? Just about which brand is better, quality wise, lasting wise, etc. Thanks.
