Advise: I just purchased a K2 Zed 2.2 last night at ****’s Sporting Goods for ~$250, I originally went there for the Diamondback Outlook for ~$200 but the specialist talked up the Z2 pretty well. He stated that the Z2 was better equipped with SRAM instead of Shimano on the rear, had a bigger diameter Seat post, and better handlebar design (by that I mean the internals at the frame). He basically went on saying the K2 was an overall better bike in many ways. However, as I peruse the WEB I do not see as large a following for the K2’s as there is for the Diamondbacks. My last bike was a Diamond Back Outlook as well, although an older model with no front suspension. I have had no issues with the bike and it performed well but I am not against upgrading either. Is there any knowledge out there supporting the $50 premium for the K2 and the quality differences between these two bikes? I appreciate the answers in advance, thanks
