G'day,
but a composite frame won't 'fatigue' the way alu does. With alu you can have 'unseen' fatigue that can lead to catastropic failure. With carbon, unless the fibre is actually broken, it doesn't fail. Not that I'm a fan of Trek's, but they have the right idea with the warranties on the carbon frames, which basically says, treat it right & it won't break,
