So I go a decent ride recently, wasn't really into the biking scene and followed REI's advice, ending up with a nice bike...but not dual susp. I told the people there that I would be doing 60% DH, 40% climbing/biking around town. After riding this thing DH, I realize that I need a dual bike. My question: should I test the 100% satisfaction guarantee and return the bike for a dualie- or just try my best with this hardtail? Thanks for helpin out this Mtb. JONG.
