I hear that such breakages are common, *BUT!* How much of this is due to poor design, and how much due to the material? I suspect that, if such things were well designed for the material, they'd be plenty strong and -- I wonder? -- as light as aluminum?
Again, I'd like to see a comparison of the materials as suitable for bikes, abstracting from stupid or otherwise inadequate design. Certainly durability would be a very important criterion to compare.
