too many friends have had their carbon fiber bikes melt when left in the sun--not for me

my titanium bike, a semi truck backed over the front triangle--and it only had a few scratches that I buffed out with a brillo pad--nice

steel rides nice, but most frames weigh at least 8 lb.

aluminum is light and has good power transfer, but one dent and it crumples like reynolds wrap!



lol ;-)
