you cannot see delamination from the outside .. good luck , tap wood , cross your fingers, etc.

<only if you bought it new, will you know its history>


Good luck, buying used..

Fear mongering by Luddites is a favorite hobby on the Interweb.
You know the condition and history of your machine. Take the common sense precaution of carefully examining every tube, joint and fitting for de-lamination, stress cracks and anything suspicious looking.
If all looks good carefully re-assemble, test ride w/ increasing loads and if all is well: Have at it.

Having said that if you are concerned about your frames's safety and integrity, don't ride it.

If you really want to have it checked then ultrasound is what you need ,not X-Ray. It will need to be disassembled down to the bare frame.

@Bandera has good advice. Inspect it visually, stress it a little by hand, build it, ride it cautiously and then enjoy.

I ride a 16 year old carbon fork with 60,000 miles on it. An acquaintance rode a carbon frame for 170,000 miles over a decade.

I think they should be ok since many CF frames were meant for high end use. Even vintage CF frames weigh less than many modern steel frames.

Only 17 years old...

I think you need to let it age for a couple more years before taking it out for a ride. It is far too new.

Wow. Have we really already arrived at the point where CF bikes can be considered “vintage”?

I had a friend who rode one of the lugged style carbon frames that were initially built. I can't remember the brand. Probably giant or raleigh. They have straight carbon tubes bonded inside aluminum lugs.

The bike is not going to break. It's just a flexy piece of mush.

Sometimes we retire stuff due to ride quality, not safety. It's not an age thing but a design thing. I don't think that bike was ever good.

At 17 years though, your carbon bike is a lot newer than the style I'm talking about and hopefully a much better ride.

Mine is 30 years old. I rude it once a week. I think it's vintage Carbon. Yep, aluminum lugs, carbon tubes.

I was thinking the same thing.

That was supposed to have been an impossibility according to some.

The same thing as the predicted adhesive failure by Proto-41-ites of the Vitus 979: Nothing.

My '07 carbon Roubaix is still going strong. Riding better than ever with a wheel upgrade. The aluminum Mavic rim cracked after 10 years around the spoke nipples, so I picked up a set of Reynolds Stratus Elite - great wheels. Transformed the bike. Frame hasn't exploded yet.

Keep in mind what CF bikes are. They are CF reinforced plastic, and plastic gets brittle in its old age. Unlike metal it fails instantly. As usual Im sure I will get push back on this, but I am a realist.

Still on these two 25 year old's on a regular basis. The paint Zipp has over 109,000 miles on it and gets a new paint job about every 4 year. The bare carbon Zipp is in at 26,000 miles and I converted it to a single speed 5 years ago.

Actually if one reads the threads you start over and over again on why Diamond Frame Bikes Are Health Hazards, Rim Brakes Are Unsafe, Cycling Kit Is a Waste of $$$, Too Many Gears, Riding Fast is Stupid, Roadies are Snobs and now CF Bikes are Plastic "realist" is not the term that springs to mind.

I never said rim brakes were unsafe, I said disc brakes are better for several reasons. The rest is common sense and logic unless you are out to impress a few impressionable people.

A close friend of mine recently brought me a carbon fiber bike that he found at a suburban New Jersey garbage dump. It's a near complete 2008 Fuji Team 10 speed. Only missing the wheels, seat, & crank arms. I stripped it down to the bare frame in my shop. Clean and polished frame. Carefully examined & tested frame for possible damage & could not find any faults. It's all back together now. Just need to put the tires on. Do you think it's safe to ride?
