however this is not the thread of broken brames,i've seen broken carbon frames (and to break in front of my eyes) (nor specizlized by the way). both, road and Mtb.
The breakage it has always been due tio a hard and dry thud/knock...ie, trying to junp a chain in the middel of the track at speed, jumping and lñanding over rock gardens, being tripped over by the peloton (in road).....
i've never ,nor i imagine it, seen a broken carbon frame due to the pedalling pressure....
Alloy frames under a dry thud may deform (and not recuperate the form afterwars, so they keep with the nipple made by the thud, and you may keep riding). Instead, carbon frames either recuperate the form or break (completely or appear scars) under a dry thud
From what i gather, specilaized frames are a bitmore robust (a weight more) than other brands....fot instance the s-works full-suspension epric frame weightes more than other full supesnsion carbon frames (scott genius, etc)...in fact the epic s-works is not a light winnie carbon frame nor bike....mine wieghted new in box about 11,2-11,3 kg
and surely a few grams more of carbom means one layer more of fiber carbon glued with epoxyresin...... surely the advertized specialized "10 fact r carbon frames for the s-works (mtb o road)" mens something of these....
so keep on riding hard and nener never fall however much you push your bike...this will garantee both, not breaking the frame and beeing the first some day
