Whats the most effective way to put a Diamondback Response through its paces to ensure its the perfect fit? Ive seen some folks recommending the standover test where you straddle the bike with your feet flat on the ground, but isnt that a bit too simplistic? I mean, what about the actual riding experience? Shouldnt we be looking at factors like seat height, handlebar reach, and pedal stroke to get a true sense of comfort and fit? And what about the importance of test-riding the bike on different terrain - smooth roads, rough trails, and everything in between? Can anyone shed some light on the most comprehensive approach to testing the comfort and fit of a Diamondback Response?
