|Does Carbon Fiber get less stiff over time?||Citius|

|Will my Trek 5500 feel less siff two years from now than it does today? Is there any scientific way of measuring this? Do other frame materials feel differently after thousands of miles of riding or is this just a myth?

Don't worry about it too much - even though all frame materials get less stiff over time, carbon fibre (especially OCLV) is the strongest, most rigid and stiff material on the planet for making bike frames - so your 5500, if you look after it, will last longer than you will probably wish to keep it. I plan on riding mine until doomsday!

|This is why skis "go flat" with time. Either the matrix cracks, the fibers break, or the fibers pull out of the matrix. This problem has decreased significantly since the first "modern" CF bikes came out (Kestrel in about 1986). Whether it happens to you depends on things like your weight, your riding style, whether you crash, and your annual mileage. For most people, it is not an issue.|

|This is one of the many myths about carbon. You'll also hear that your frame will disentigrate upon impact, but that's not true either.
I've had Kestrel 200 Sci for 10 years and it's still is as stiff as the day I bought it. You have nothing to worry about. A bike frame and a pair of skis are completely different things.
