While out on a ride yesterday, one half of my handlebars broke off where they enter the stem. I was accelerating in the drops, and when they broke, I went straight to the asphalt, landing with my weight on my elbow. It wasn't a great way to land, but I was glad it wasn't my head and I wasn't in traffic. The bars were Modolo Q-Even. They were made of 6082-T6 aluminum and they list at 310 grams (mine were probably heavier since they were 46cm). So they weren't a light weight bar, and I think the T6 means they were heat treated. I am tall, but weigh 180 pounds. I only had about 1,500 miles on the bars. I have a Nitto Technomic stem (26.0). This is a quill stem on my vintage Serotta. I won't be able to ride again this year, but hopefully I will by next summer. Does anyone know of bars that have a reputation for being bombproof? I don't know what else to go by since some bars don't even list the type of aluminum, and I have no way of knowing how they might be built where they enter the stem. I just want a set of bars that won't break, and I don't care how heavy they are. I also broke the bars on my Cannondale touring bike a few years back, but I didn't crash since I was pulling up on the side that broke. I was able to keep my balance and come to a stop. I knew those bars had seen some miles of stress from the weight of panniers. On the other hand they were stock equipment on what was sold as a touring bike.
