Can someone explain "flex" to me?
I was talking about 29er bikes with a buddy of mine recently who in avid rider. He complained about the "flex" of the 29er wheels. I have heard others say similar things. Can someone explain what that is exactly?
Also, I hear a lot about stiffness qualities in carbon vs alloy. Can you actually discern the difference in stiffness in the two materials without literally trying to bend the material?
Just a couple of things I was thinking about while daydreaming today. :D
