Grant Petersen / Rivendell on carbon forks
Any comment here on this strong anti-carbon position? He's making up
steel forks, not expecting to sell many, and even buying back your old carbon fork, such great risk does he think the carbon fork poses to your health. http://www.rivbike.com/products/show...ms-fork/50-718 Not a troll's question. I ride a glued aluminum fork, myself. I do wonder how much fragility can be built into carbon forks while paring more and more weight off of them, and at what place riders, even pros, say, "No, that's just too risky."

Consider a carbon fork a wear item and replace it periodically, every few thousand miles. His statement "Maybe it was a manufacturing flaw that went undetected, or a weakness that developed through use" is true, but the latter is much more likely than the former, and the former can occur no matter what the material (though it's less likely with steel or aluminum than with CF). |

Harry Travis Pine Barrens of New Jersey USA Carbon forks rarely fall apart, and when they do, it is because of inadequate bonding, e.g., someone forgot to glue a leg to a crown. That has been my experience. *I have seen steel forks break for the same reason -- someone tack brazed the leg to the crown but did not finish off the fork. Aluminum forks can fall apart for the same reasons, and historically, some were dangerous due to the joining of dissimilar materials (Viscount/Lambert). *Modern bonded aluminum forks are everywhere and seem to have a good service record. The deal is that with CF, it can be damaged in a way that does not show and then can fail later. *I ride CF forks and have since they hit the market (starting with first generation Kestrel forks) and have never had a set fail. *But then again, the one time I had a bad frontal crash while riding a CF fork, I replaced the fork just to be safe (it was a cheapie fork). *Absent damage, though, they aren't just falling apart. Grant is right that CF is not as safe as steel under some circumstances (where there is latent damage). *His forks look like a nice product at a not too outrageous price. *I like that crown (with no internal plug stress risers) and the drop outs, too. *If I had a steel bike that needed a fork, I'd consider that one. -- Jay Beattie. Every con-man's story needs a grain of truth. But if crabon forks were raging liabilities--they would get banned like Jarts were. Peterson's replacement forks are handsome and well priced--his tactics of marketing through FUD are loathsome. |

I'd characterize Mr. Petersen as more of a "retro-grouch" - I suspect that he honestly believes that "steel is real" even if I don't always agree with the dangers of crabon fribe. (I wouldn't ride my Cannondale if I felt that doing so was putting me in imminent danger of faceplanting...) At worst, he's guilty of hyperbole... nate -- replace "roosters" with "cox" to reply. http://members.cox.net/njnagel |

Peterson's replacement forks are handsome and well priced--his tactics of marketing through FUD are loathsome. "Con-man"? "Loathsome"? You're the one trying to con us, Maxine, with loathsome misrepresentations. All we can see about Mr Grant Petersen is that he dislikes carbon forks, he states his reasons strongly, and he is willing to back up his judgement with his own money by trading in and destroying carbon forks. Seems to me that Mr Petersen is an admirable crusader -- and you're behaving like an hysterically overwrought schoolgirl once more.

I asked them a couple of questions, both answered in the negative: - If I send in a CF fork with the crown race still on it, can they transfer it to the Carbonomas fork? - Given that they won't offer that service, can I just send them a video of me destroying the CF fork so I don't waste time and money boxing it up and sending it in? So are they really destroying these "dangerous" forks or selling second-hand carbon forks somewhere under a different name? |

If you torque the stem bolts to enough preload that they don't fall out (and cause your bars to fall off), they break. Trek is specifically instructing people to install their stems so that the bolts fall out. Now that's a safe product! -- sig 89 |

They (jokingly?) said they might make a coat rack or something out of the CF forks they get as trade ins. My guess is they might also have more sword fights with them, but this time carbon vs. carbon rather than carbon vs. steel. |
