Bike Frames: Materials/Design--What's Best?(6 posts)

Bike Frames: Materials/Design--What's Best?Slipstream
Mar 8, 2002 9:03 AM
My question is: what do you look for in a frame and why?

With so many choices in frame materials (steel, titanium, aluminum, carbon, plastic[?], composites) as well as design,
what do you look for and what is best?

Obviously, you need to ride it and select one that fits best, fits within your budget and is best for the kind of riding you do.

Steel still may be the best overall frame, but weighs more. Aluminum can easily be damaged. Carbon can experience complete failure without warning. Plastic is on the horizon (and cheap). Ti is great.

What is more important: material or frame designer (and build quality)? Some say the Colnago C-40 carbon is the best bike to ride. Or is it a Calfee, or Trek, or Giant, or Pinarello, or so on.
