Road Cycling “It is by riding a bicycle that you learn the contours of a country best, since you have to sweat up the hills and coast down them. Thus you remember them as they actually are, while in a motor car only a high hill impresses you, and you have no such accurate remembrance of country you have driven through as you gain by riding a bicycle.” -- Ernest Hemingway

What's the usable lifetime of a new CF frame?

Are newer techniques in CF construction able to replicate steel frame longevity?

Possibly correct. Unless it asplodes.

Longer than steel, carbon does not rust.

Depends on whether it has disc brakes and thru axles....

If you look at fatigue testing data, a well built cf frame out performs steel frames.

Absent crash damage CF frames will last a very long time. And if you do have crash damage, it's more economical to repair, than a TIG welded steel frame

The value of the highly accurate number I provided is that one knows precisely when the asplosion will occur. You can invite your friends for a viewing party. They have to bring the beer, of course.

Easy. It's done when it hits the garage when you forgot to take it off the roof rack.

I have over 50,000 miles on my Trek frame and fork, still perfect. I suppose the lifespan is indefinite.

No. They have yet to figure out how to make CF rust from the inside.

By the way, the accurate and precise picture looks an awful lot like my pistol targets at 7 yards.

Hard to say. I looked at the source code (the HTML code appears to have been written in notebook) and there is no date in the "head". There is a reference to a 2008 email and a link dated 2010.
