A question for the engineers among us...
One thing I love about cycling message boards and websites is reading stuff by folks with backgrounds in engineering, like Jobst Brandt, and what they have to say about WHY bicycles perform as they do. I recently made an alteration on my bike that had unforeseen, baffling consequences, or I'm going mad. Check it out:
My main commuter ride is a 1987 Schwinn Le Tour, True Temper 4130 Chro-Moly, I'm guessing made in Japan. I've updated most of the components, because I absolutely love the frame and fork, which are lighter than many I see for sale nowadays,(Surly, IRO, etc.) The ride is great, but a couple weeks ago, I bought a rear rack for it. This aluminum Delta rack seemed to "deaden" the ride and make the bike feel much heavier, even with nothing on it. Could the "acoustics" of my frame have been changed somehow? I took it on and off several times to make sure and I really don't think it's my imagination. Thanks in advance for your replies.
