Hey, I recently went up to my local century cycles and talked to a person about a new bike. I currently ride a NEXT bike I bought from wal-mart for very low expense a while ago, and its not cutting it. I was drawn to the GIANT RINCON, however he suggested the DIAMONDBACK RESPONSE, or the DIAMONDBACK RESPONSE SPORT. although I know these are relatively inexpensive bikes, being 16 thats a big chunk of change for me, and i was curious if anyone owns or has owned these bikes. Id love some input before i start saving and make a decision on one. thanks a bunch for any feedback!
