Post-recall R-Sys wheel failure
"Robert Chung" wrote in message
... http://www.velonews.com/article/9305...-wheel-failure This "modern" low spoke count wheels are failing like crazy. Not as bad at that one of course but more and more people are going over the bars. Also carbon frames are failing a lot more often than it's being let on. Steel frames (though my Look and my Colnago are heavily enough built that I don't have to worry about it) and 32 spoke count wheels are looking better all the time. |

How do you know that CF frames are failing more frequently than is being reported? |

Steel frames (though my Look and my Colnago are heavily enough built that I don't have to worry about it) and 32 spoke count wheels are looking better all the time. That's a severe oversimplification. You can build a very sturdy low-spoke-count (20 front 24 rear) wheel that can last a very long time. I've got a set of Bontrager XXX-Lites that now have 21,000 miles on them and have literally never been touched with a spoke wrench. The issue is when we try to build stuff as close to the edge as possible, and it's not the material used that's the problem, it's how it's used. As for steel, the manner in which it fails may be different, but trust me, many, many steel frames failed back in the day. Typically severely-buckled downtubes. You can claim oh, a "soft" failure that doesn't cause a failure. Not quite. On a "tight" frame, the front wheel would come back and hit the bottom of the downtube, bringing everything to a sudden, screeching halt (I'm a member of that club). If a steel frame wasn't crashed, and lived to its natural end, you'd often see a torn seat tube, starting on the left side halfway between the front derailleur and the bottom bracket. And before we had cassette hubs, a lot of broken right-side dropouts, where it connected with the chainstay. The biggest issue with carbon is that people crash and don't look over things very carefully afterward, due to their hope that everything's OK. Denial. As in, don't want to know, it seems to ride OK. Plus the cost of repair is so high, but that's true these days regardless of material. We've entered the era of disposable frames. They do everything fantastically as long as you stay upright, but if you think a 2.5 pound frame can hold up as well as a 3 pound frame made of the same material, think again! The problem isn't with the materials, and maybe it's not even the design. Maybe it's people who are willing to shell out $7k+ for a cyclocross rig that can be destroyed in one outing. Maybe the fact that there are customers for that sort of bike has skewed what the industry believes we want (or is appropriate). --Mike Jacoubowsky Chain Reaction Bicycles www.ChainReaction.com Redwood City & Los Altos, CA USA "Tom Kunich" cyclintom@yahoo. com wrote in message ...
