Reliability of carbon MTB frames?
Now that there are a large number of very lightweight carbon mountain
bikes on the market, anyone care to comment on how well they hold up under real-world conditions? High end hardtail carbon frames are now only slightly heavier than carbon road frames. Can these bikes survive rock impacts, crashes, etc, as well as aluminum bikes? Are those of you in the retail world seeing customers come in with ruined bikes? |

There is no reason that a correctly designed frame using a quality composition would not hold up as well as an aluminum frame. If anything, carbon fiber would be superior for this since for the small bangs, it's going to flex and absorb the impact, rather than denting. The $64,000 question though is on the large strikes. Watch an F1 car crash during a race and pay attention to the front suspension arms. Do you want your frame doing that under you when you go sailing off that 15 foot drop you didn't see ;-) Hopefully any crash stories will come with the make and manufacturer of the frame. Ted |

While I don't ride CF, from what I've een from friends that ride CF and from what I've read, there is no reason for CF not to do just fine. You can get a very light CF frame too that will likely do great. Depending on terrain, however, I think, again, from my own experience, that the most important thing is good suspension. A well designed frame with good suspension is more important to me than the material if you are going to go through really rough stuff. Aluminum can be almost as light as CF but a lot less expensive. So, for MTB frames I would think that AL and suspension make the best combination of efficiency and value. There are people that still ride hard tails. However, they don't go where the full suspensions go and in rough stuff they don't climb like full suspension bikes. |

As an observer of mountain bike fashions, I am now seeing carbon frames (esp the 2009 model year) that are substantially lighter than years past. Are these new very light carbon frames sacrificing durability? I also wonder whether consumer perceptions about what constitutes adequate durability have changed in the MTB market. Seems to me that current consumer-level road frames are substantially more likely to be destroyed in relatively minor crashes than 5-10 years ago, and road bike buyers accept this tradeoff. Has the same thing happened for MTBs? |

I wonder this myself. I crash my MTB, sometimes hard and onto rocks. My aluminum frame is beat beyond belief, with dings and gouges galore. I have a hard time picturing carbon standing up to these types of crashes. I assume they'll put up with riding fine - how well they'll crash makes me nervous |
