carbon fork dropouts
Are there any fork carbon-dropout durability issues, it seems like metal
might be a better material...for the dropouts? Could Carbon fiber crumble/crush under compression over time (compression from the skewer), but the fork makers probably have it figured out ok. |

Carbon fiber composite only has metal-like strength in the direction the fibers are oriented. Perpendicular to the fibers, it's just ordinary epoxy. Chalo Colina |

Yes, they can be crushed, either by the front wheel skewer or on a car rack(which is a BIG no-no). marketing run amok, the weight savings is teeny, tiny... |

Yeah, they've figured out how to sell lots of replacement forks (something that should otherwise last a lifetime) once the fragile fork ends get ruined. Good for business! |

This falls under a new category: super stoopid light. Whatever happened to basic common sense? |

Easton SLX 90 fork has carbon dropouts and it has been around for about 2 years. Litespeed Real Design HP Pro fork has carbon dropouts, with a covering of aluminum on both sides. Its been around for a few years. Look HSC5 fork has been out for a year now. It would be nice if someone who owns the Easton or Litespeed fork could comment. |

carbon fork dropouts
I think Giant is using carbon dropouts many if not most of their road
bikes now. This is more significant since it indicates the potential for a flood of OEM forks with carbon dropouts in the years to come. The real reason the manufacturers are adopting this it to save money rather than take advantage of the teensy weight reduction. On a side note. It looks like Giant has dumped most of their aluminum road frames for 06. It is also curious that the low spoke count wheels are only on their cheaper models. I wonder if they got tired of taking the hit on so many warranty returns. |

Once the design and tooling are paid for, a one piece fork is cheaper to make, durability be damned. As an added benefit, the makers can charge very high prices for the first and second generation one piece forks, so the tooling gets paid off pretty quickly. On a side note. It looks like Giant has dumped most of their aluminum road frames for 06. It is also curious that the low spoke count wheels are only on their cheaper models. What's this? Signs of intelligent life in the bike market? I wonder if they got tired of taking the hit on so many warranty returns. Perhaps they have rediscovered the 36 spoke wheel?

Yes, they can be crushed, either by the front wheel skewer or on a car rack(which is a BIG no-no). Even aluminum and steel dropouts are bad news when combined with lawyer lips and a fork-mount roof rack. How many forks have you seen wrecked because somebody had a difficult time keeping the bike propped up while simultaneously working with the adjustment of the QR? And, of course, over 26 years you're going to get a few people bringing bikes into the store, claiming their fork is defective because the dropout is bent outward at a 45 degree angle, and it just happened riding along. Somehow. It doesn't take too long to explain to them what happened; of course, you have to do so in a non-incriminating fashion, somehow convincing them that you believe it's possible they might not have noticed it happening. The thing we have to do sometimes to maintain a customer's dignity... :) --Mike Jacoubowsky Chain Reaction Bicycles www.ChainReaction.com Redwood City & Los Altos, CA USA "Ozark Bicycle" wrote in message oups.com...
