At yesterday's club after ride chat, the subject of frame failures came up. Probably from a few members riding strange bikes (other than their normal bike) and I learned that at least 4 frames (within our club) have failed and how the manufacturers are handling the matters.

Three are Trek's but none of the failures are related and one was from an accident. One is particular seems due to a weak design of the rear frame triangle. One is the top tube (maybe from using a bike rack?) and the other from a rock (Mtb) hitting the BB part of the frame. Trek is "looking" into these frames for over a month and slow to respond.

The fourth one was on a Cannondale (Old Mtb) and they replaced it within 30 days and upgraded a few dated parts. IDK why, but they did it.

Has carbon fiber frame failure been an issue with other fellow cyclists? I don't think this is a "Trek" issue, as we have a large number of Trek owners in the club due to good team support from a local dealer. That dealer has his hands tied with the frame issues though.

What I've learned is that CF isn't all what the hype (marketing?) makes it out to be. A top tube failure from using a bike rack seems like a design problem. A rear triangle break (yes, apart) is another design flaw. I don't think anyone can build a BB frame strong enough to stand up to hitting a rock (but maybe a protector plate?).

I'm glad I still have my old alum bike. I'm sure that alum frames have issues too, so what's the answer titanium?
