The fork mount racks seem more secure because the bike doesn't move around as much as on a rack where the bike sits on both wheels. Nut it's still just as secure. What about a roof rack that holds to bike upside down and where the bike is secured by the handlebar and the saddle?

That is if anyone was still making such a rack. Cheers |

Back in the days of structural steel rain gutters I built one of those. |

Has anyone had any damage to bikes simply from using a rood rack? A friend of mine had his C40 Colnago have its head tube simply break off. To me it looks like a manufacturing error but I wonder if it was caused because for 15 years he was carrying the bike on a roof rack. I can't imagine the bumps and centrifugal force and wind sheers not having some sort of effect. By the way - since carbon fiber bikes are (or at least were) sensitive to UV light what would you think about long term driving with your bike on a roof rack? I'm trying to figure out how a couple of bikes I saw fail did so for no apparent reason and after almost 10 years. While other CF bikes that were notorious for failures (those early Trek fully molded) are still running strong after 15 years. |

The key step was learning where the car's hard attachment points were. I peeled up the two longitudinal plastic trim strips that run down the sides of the roof. There were two 6mm female threaded holes on each side. I drilled holes in the feet of the old rack and screwed it down. I wonder if you can do something similar. I actually take it off the car each time we're done with it, because I have to do lots of freeway driving these days. It goes on and off easily. - Frank Krygowski |
