Now they do make carbon bar/stem one piece combination that would be OK but no more two piece carbon setups for me. I guess this is why the pro's use the one piece bar/stem. Glad you were not injured. Modern light stems/bars, and not only carbon, need careful setup with carbon paste, even torque to manufacturer specified values and lubricated threads except where manufacturer specifies dry or threadlock. Also, take care to keep the faceplate evenly spaced top and bottom (and side to side on a four-bolt) during torque sequence and especially at final torque. Insufficient or uneven torque is bad but overtorque is equally bad or worse. Get a proper scaled or click wrench if you don't have one already. To repeat, modern ultralight aluminum stems share many foibles with carbon stems. The days of 'crank it tight and go ride' have ended. -- Andrew Muzi www.yellowjersey.org/ Open every day since 1 April, 1971 I am most certainly NOT a fan of precise torqueing. That was what I originally did with this bar and it promptly not only rotated on the first hard bump but it rubbed all of the grit on the bar interface off.. Tightening it to what I felt was correct greatly improved the "hold" but it too slipped. Then I added carbon paste as directed and while it took a hell of a bump it too slipped though nowhere near as badly as the initially installed and torqued. Not a fan of precise torquing? What does that mean? You are a fan of imprecise torquing? That is weird for someone with a technical background. If my CF handlebars slipped and the grit of the interface was rubbed off I would consider the handlebar as not safe anymore and replaced it. I build my bike with a CF handlebar 5 years ago. Torqued it precise to spec and it never slipped. Never touched it after the initial build Lou I didn’t build my bike myself but I bought it from a shop I trust.. Never had any problems with the bar slipping. Never really heard of this as an issue... Well, neither did I. But then most of my carbon bars weren't designed with minimal weight in mind. |

A carbon fiber bar failing during an out of the saddle sprint or riding at high speed on a descent (or even flt road) can have rather catastrophic consequences for the bicyclist. They could get that rundown feeling that even Geritol won't relieve. Cheers |

One of the causes of the great depression of the 1930's was the Smoot-Hawley Tariff which imposed near-record tax rates on a wide range of imported goods, which resulted, of course, in American trading partners retaliated by imposing tariffs on U.S.-made goods. As a result, world trade fell by two-thirds between 1929 and 1934. One wonders, will history repeat itself? -- cheers, John B. |
