Carbon frame- longevity

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

Carbon frame- longevity

Having never owned a carbon bike before, should one expect any long-term issues? I'm wondering if buying new for the frame warranty is worth it.

What kind of long term issues are you talking about?

Hhaving a lifetime frame warranty is pretty nice if you plan to keep it many years.

Long term...you'll get bored and want another bike, most likely before you crash... or break... or drop a chain sawing the BB area or chainstay in half....Most likely.

Who doesn't want a warranty on what they purchase if you can get it? Especially even partial crash-replacement coverage.

My neighbor has a first generation Specialized Allez he has like 100,000 miles on, and he is the original owner. I told him when the frame break, Specialized will replace it as he has the original bill of sale from like 1992.

Most CF frame problems are from damage not covered under the standard warranty. If you are buying a frame from a mainstream manufacturer, I wouldn't worry about a warranty.

Crash damage is easy to spot a possible problem.

I seem to be going through Trek CF frames about once every 10 years. The original was 1993, then I got a warranty replacement for that in 2005 (bb shell came unbonded), and I got a replacement for the 2005 last year (crack in the seat tube originating at the lower bottle mount).

I don't mind the free upgrades every 10-ish years.

That said, I also have a Trek CF mountain bike, and I've crashed it literally hundreds of times, much to the dismay of two Bell helmets and a bone in my left hand. But nothing I do seems to phase that frame. I guess it must be way overbuilt.

Make sure to buy a large cooler so you can store it in ice. That way it'll maintain it's freshness.



In all seriousness, I own 2 "vintage" lugged carbon frames, one from 1990 and one from 1995 (25 and 20 years old respectively), and they are both fine. I've wiped out on my 1995 Trek 2120 in the wet and it took a huge impact and it had no cracks or fractures, however the STI levers got a little scuffed.

CF is pretty tough and durable, despite what a lot of "steel is real" lifers seem to think.

A friend has about 40k miles on a Madone 5.0, probably about 5 years old. He just replaced the drivetrain.

Bah, I bought my last two carbon frames on ebay... no warranty, no issues whatsoever (both Specialized Roubaix frames, btw)

It's so much cheaper to get a used frame, I reckon I can just replace it out of pocket and I'll still be ahead.

Different than metal, a carbon/resin matrix has an almost infinite fatigue life. So a properly constructed frame will possibly last forever.

Right. For most people, this is it. You might like an old bikes for sentimental reasons or just are into vintage, so that's good. But most people want to move on to the latest.

I've got an old bike - quill stem, 1" steerer, heavy fork, rear that needs spreading to accommodate more gears, handlebar that flexes, overall heavy weight, faded paint with kicks snd scratches.

I've wrecked more metal frames than carbon fiber but that's not to say I haven't tried. LOL

Edited to add, you're riding an aluminum bike with carbon fiber forks in a region of the country known for hard winters (assuming Location from profile). Were you concerned when you bought the bike that the fork might not be durable enough? Be able to withstand exposure to road salt, etc.? For purposes of durability, I consider the fork to be among the most important features. Any frame can take damage from rocks, falls, dropped tools (if they're heavy enough), and so forth. There are plenty of damaged frames pictured on the "web" to satisfy anyone's curiosity. But a broken fork is particularly nasty because it can lead to steering and braking failure with a almost guaranteed fall too. So, whatever frame you get, make sure you get a good fork and watch that it doesn't show signs of failure.
